Developing low-cost, durable, and improved membrane electrode assemblies for PEM fuel cells and PEM high-pressure electrolysers, to be used preferably in systems with hydraulic compression
Producing energy using renewable sources is a dynamic process and thus requires similarly dynamic storage possibilities. Project “HyPresMEA” applies several approaches in order to raise the competitiveness of hydrogen-based storage systems, as compared to conventional technologies. The use of intelligent conservation methods should allow the low-cost production of membrane electrode assemblies for PEM fuel cells and PEM high-pressure electrolysers.
The project tests the use of durable structures made of corrosion-resistant titanium interlayers as well as carbon-nanofiber graphite layers as a substrate for the catalytic layers. In order to spread the noble metal catalysts as much as possible towards the membrane, the pore sizes of the components should vary among the different layers.Moreover, a novel proton conducting membrane will be developed using a modified polymer based on polystyrene, which improves proton conductivity and lowers costs. To ensure an optimum bonding of the substrate, the noble metal catalyst and the membrane, the modified polymer is also added to the catalyst layer.
