3D-PakT - 3D printing of porous catalytically active transport layers
A sustainable energy and mobility infrastructure based on hydrogen as an energy carrier can only work if hydrogen is provided by water electrolysis powered by renewable energy sources.
Proton exchange membrane (PEM) water electrolysis is an ideal candidate, due to its advantages such as high flexibility, high achievable current densities, technically simple process engineering and high hydrogen purity. However, this is offset by high material and manufacturing costs, especially for the oxygen-generating electrode, where harsh reaction conditions prevail.
