Development of a Cost-effective anode for PEM water electrolysis - DC-PEM

Project summary

PEM electrolysis represents a key technology in the transformation of the energy sector towards hydrogen as energy carrier and storage. In the project, manufacturing processes are to be further developed in such a way that a more cost-efficient production of PEM electrolyzers becomes possible. To boost performance of the electrolytic cell, the focus must be on the crucial OER at the anode. Starting with the paper production technique to produce highly porous titanium structures as current collectors and porous transport layers, pretreatment techniques as the hydridation of the carrier titanium and catalyst immobilisation based on pulsed galvanic deposition and CVD-processes will be further developed to reduce the use of precious metals compared to state-of-the-art electrodes. At the same time, a process for recovering the precious metals will be developed. An industrial partner in the consortium and a well-established advisory board will ensure the transfer of technology to industry.
