Fumatech Bwt Gmbh products

The PEM water electrolysis application has been developed into a technology meeting the demand of highly efficient green Hydrogen production in MW-scale. The central part of the technology is the membrane that serves as ion conductor and at the same time also as electrode separator. The fumasep proton-exchanged-membranes for water electrolysis are tailored to the demand of high efficiency. The membranes are available typically with reinforcement, enabling and adoption of the membrane to a large cell format and reducing the swelling of membrane. The FS-membranes are made from short-side-chain PFSA polymer. These membranes facilitate the HHV (higher-heat-value) efficiency as high as 85 % at current density 2 A/cm2. The membranes feature particularly low swelling ratio and superior strength properties.

The alkaline water electrolysis application ranks among the oldest electrochemical processes having well-matured system’s design. The progress since 2010 allowed significant improvement to that-time state-of-the-art technology. The central part of the units is the fumasep anion-exchanged-membrane FAAM that facilitates the increase of pressure difference. The membrane supports also the enhancing of absolute operational pressure, helping users to optimize Hydrogen production in MW scale. The FAAM membrane features reduction of the potential, too, which yields higher HHV (higher-heat-value) efficiency at increased current density compared to the porous separators. The FAAM membranes are available typically with reinforcement, enabling adoption of the membrane to a large cell format and reducing the swelling of membrane.
