Carbon Capture Technology World Expo
Optimized microporous transport layers for PEM electrolysis
)
Proton exchange membranes (PEM) are one of the most promising technologies for the production of green hydrogen by electrolysis. To reduce the material and manufacturing costs for PEM electrolyzers, Fraunhofer ISE is researching scalable production processes for catalyst-coated membranes (CCM).
At the Hydrogen Technology World Expo, we will present microporous transport layers (MPL), which have been produced for the first time in a scalable manner on standard industrial screen printing systems. The approx. 20 µm fine MPLs enable the use of catalyst layers with significantly reduced iridium loading (ultra-low loading), as they considerably improve catalyst binding and thus utilization. They also simplify the use of thinner membranes so that ohmic losses can be reduced.
