Membrane electrolysis is a process in which two electrode reactions, namely cathodic reduction and anodic oxidation, are related to the transport and conversion of charged ions. In membrane electrolysis, electrode reaction is an essential step in the actual material separation process. The task of the membrane is to hydraulically separate the anode circuit (anolyte) from the cathode circuit (catholyte) to avoid unwanted side reactions, to combine electrode reactions with separation steps or to separate the products formed at the electrodes. In the case of water electrolysis, these may be gaseous products, such as oxygen and hydrogen,

Frequently observed electrochemical reactions include metal deposition and anodic oxidation to form hydrogen and organic compounds at the cathode and ions such as chloride, cyanide, nitrite, etc.
Both oxidation and reduction reactions are of industrial interest depending on the separation task. The production of chlorine and caustic soda by sodium chloride electrolysis is the most important membrane process in the world, with an annual output of about 48 million tons of chlorine, of which more than 30% is converted by membrane electrolysis process.In addition, membrane electrolysis is used for the production of sodium hypochlorite for the disinfection of drinking water. * More recently, electrolysis, which is used to produce ozone, chlorine dioxide or hypochlorous acid, is also increasingly used to disinfect drinking water.

PEMelectrolysis
As part of the concept of electricity to gas, hydrogen production byPEMelectrolysis is one of the key technologies for future energy production. This process represents a reversal of the function of fuel cells in which the basic components H2and O2react electrochemically by applying a voltage. As a highly functional membrane, the proton conductive membrane is a critical core component, and functional chemical side groups in the polymer matrix result in the transfer ofH +-ions from the anode through the membrane to the cathode. There, these protons recombine with electrons, which are also conducted through electrical conductors to the cathode to form high-purity hydrogen. At the same time, the oxygen produced is separated on the anode side and can also be stored in a very pure form or used directly.
Anodic reaction H 2 O→2 H + + 0.5 O 2 + 2 e -
Cathodic reaction 2 H + + 2 e - →H 2
In general equilibrium, when water breaks down, each water molecule forms one molecule of H2and0.5molecules ofO2 .
PEMwater electrolysis allows high current densities to be achieved, which are mainly based on the high proton conductivity of the membranes used. FUMATECH BWT GmbHoffers a wide range of textile reinforced films for this application. They are characterized by excellent proton conductivity and low crossover of reactants. In addition, it also has high chemical resistance and mechanical resistance. Especially due to fabric reinforcement, the membrane can be used at increased operating pressures. The high stability of the membrane supports the service life of the entire electrolysis system.
alkaline electrolyzed
Alkaline electrolysis is a mature industrial process. The hydrogen produced by this process has the characteristics of high purity, so it is mainly used in chemical process technology. But especially for the energy industry of the future, this hydrogen production process represents an attractive add-on tool. Efficient transfer of OH-using functional membranes-In this application, the demand for ions has steadily increased in recent years. The chemical stability requirements for the membrane materials used are very high. Use up to40%KOHsolution. The operating temperatures of industrial systems sometimes exceed80°C, and it is planned to increase the operating pressure to around 30 bar in the future.
In alkaline electrolytic cells, water is decomposed into H2andOH -at the cathode.
The electrochemical process in the cell is as follows:
Cathodic reaction 2 H 2 O + 2 e - →H 2 + 2 OH -
Anodic reaction 2 OH - →0.5 O 2 + H 2 O + 2 e -
In general equilibrium, one hydrogen molecule and one oxygen particle are obtained from each water molecule.
FUMATECH BWT GmbHoffers self-supporting and fabric-reinforced membranes with high conductivity and low H2 crossover for alkaline electrolysis . The reduced hydrogen permeability in particular represents an important benefit in improving the efficiency of the overall electrolysis system.

The films produced have and do not have enhanced mechanical and chemical stability. Another application is the production of sodium hypochlorite and hypochlorous acid for water disinfection.
Fumapem®high performance membranes for fuel cells:
perfluorosulfonic acid/polytetrafluoroethylene copolymer is a standard polymer material for proton exchange membranes for fuel cell applications. The film has high chemical and mechanical resistance characteristics, which can also be improved by using reinforcing fabrics to ensure the handling and service life of the product.
For LT-PEM
Membranesfor both applications in fuel cells are based on PFSA polymers and can be used as long side chains(LSC)or short side chains(SSC). For stationary applications,LSC PFSAhas been used since the 1990s. Thefilm FUMATECH made on this polymer isfumapem F-940-RFS. This is comprehensively characterized by various electrochemical methods and shows very good resistance in terms of chemical and mechanical stability.
SSC PFSA is the right raw material for applications that require higher tolerances in terms of power density and relative humidity. Fumapem FS-930-RFSfilm has low resistance and excellent ability to cope with short-term humidity fluctuations during operation without sacrificing performance.
Both F-940-RFS andFS-930-RFSfilms have been tested under various stress conditions with excellent results in terms of life expectancy. Short side-chain filmfumapem FS-715-RFS iscommonly used in automotive applications.
The 15µ m thick enhancement film is characterized by a particularly low electrical resistance and self-humidification under dry conditions even at high current densities. Water produced by the cathode helps increase the conductivity of the membrane. Considering the small thickness, the membrane shows very good mechanical properties and low hydrogen transfer even under different conditions.
Due to the need for high reliability, some marine and aerospace applications use fumapem PFSA films with thicknesses of 80 to120µ m. The system operates using pure hydrogen and oxygen, and the fuel cell operates at high pressure on the cathode side. Both LSCandSSCmaterials, whether as plain foils or reinforced films, meet target values for performance, durability, pressure operation, and extremely low hydrogen transfer. Allfumapemfuel cell membranes can be easily processed by knownMEAproduction processes such as hot pressing withGDE, decal processes or direct coating with catalyst. Selectedproperties of fumapem PEMFC membranes are summarized in the following table.
Due to its superior performance, hydrocarbon membranes are used in special fuel cells, such as°high temperature PEM without humidification above150 C, or DMFC applications where the fuel used is low crossover.
High temperature proton exchange membrane (HTPEM) is°the core of fuel cells above 150 C. As with classicalPEMfuel cells, hydrogen is electrochemically split into protons and electrons at the anode. Protons travel through the membrane to the cathode, while electrons travel through an external conductor to produce an electric current. At the cathode, protons combine with electrons and further react with oxygen to form water and heat. There are two different ways to generate hydrogen. On the one hand, hydrogen is produced from natural gas by steam reforming. Hydrogen and oxygen, on the other hand, can be produced by electrolysis of water. HTPEMtechnology is particularly interesting when used in conjunction with natural gas because it does not require additional expensive peripherals such as oxidation catalysts to remove carbon monoxide from the reformate, as the anode can absorb high concentrations of species such asCOandCO2without significant loss of performance. In addition,thermal management is simplified by eliminating the need for additional humidification compared to cryogenic PEM systems. HTPEMtechnology has an efficiency of approximately90 percent, calculated as the total output of electrical and thermal energy.

Direct methanol fuel cells (DMFC) are of particular interest for portable applications because they can be used very conveniently as an energy source anywhere there is no electricity or natural gas. The fuel used is methanol, which is converted into protons and carbon dioxide at the anode while generating electricity. At the cathode, protons and electrons combine and oxidize with oxygen to form water, releasing heat.
Membrane materials for HTPEM
There are two polymeric materials that can be used for this type of technology. Both are based on polybenzimidazole (PBI). The classicalPBImembrane isfumapem APand the new ultra-high molecular weightPBImembrane isfumapem AM. fumapem AMfor cathode and humidity balance operation
Although fumapem AP has advantages in wet anode operation on the anode side and°temperature tolerance above 170 C. Both films have excellent thermal stability and electrical conductivity. Depending on the operating conditions, both membrane types canachieve very high performance within an operating time of 3,000 - 20,000 hours.
Film materials for DMFC are used
One of the important characteristics of membranes * for DMFC applications is the high fuel retention on the anode side, as possible crossover not only reduces efficiency but also increases the risk of operational failure. For this reason, a strong membrane that does not readily expand or contract excessively isa critical component of any DMFC system. There are two types of membranes for this application. Fumapem E-730is characterized by very low methanol crossover and good performance,fumapem F-1850is characterized by moderate methanol crossover but very good performance.
fumasep®battery membrane:
Fumasep membrane is the new core of redox flow battery. FUMATECH BWT GmbHproduces porous separators and closed functional anion exchange and cation exchange membranes for various battery systems.
Avariety of film types are available for VRB depending onwhether high efficiency or high current density is required during charge/discharge, or a tradeoff between these modes of operation.
Porous membranes are characterized by low cost, low surface resistance, adequate selectivity and possible electrolyte transfer.
The advantage of our closed ion exchange membranes is that they achieve high coulomb yields and the lowest possible electrolyte transfer.
Cation exchange membranes are primarily liquid-tight proton conducting barriers to electrolytes. Since all RFB systems are based on cations in different oxidation states, selective proton conductive anion exchange membranes with high rejection of other cations may be the best choice for achieving maximum efficiency.
