ReMatKat – Reduction of Critical Materials in PEM Electrolysers
PEM electrolysers require rare, expensive, and otherwise critical materials, including iridium for the catalysts and PFAS for the membranes. The ReMatKat project aims to reduce the use of such materials.
As part of the ReMatKat collaborative project, we are working with ionysis GmbH to develop innovative catalyst-coated membranes (CCM) for PEM electrolysers that use significantly fewer critical raw materials. The goal is to reduce the use of iridium and PFAS-containing materials through new membrane and cell designs without compromising the performance and service life of the electrolyser.
To this end, edge-reinforced membrane structures (subgaskets), thinner membranes, recombination catalysts to reduce hydrogen crossover, and material-efficient catalyst layers are being developed and validated in individual cells.
