Electrolysis and Fuel Cells for the Hydrogen Society of Tomorrow

The conventional fuel cell membrane foil is replaced by two directly deposited ionomer layers

Hahn-Schickard develops the core components for hydrogen electrolysis and fuel cells. In the hydrogen electrolysis, water is converted to hydrogen by means of an applied voltage. The generated hydrogen can then be stored as energy carrier. In fuel cells this process is reversed and electricity is generated by the combustion of hydrogen gas. Together these systems form the fundamet for a future hydrogen society, in which huge amounts of energy – e.g. from renewable energies – can be flexibly stored and distributed. Additionally fuel cells enable a zero-emission mobility with short recharging times and driving ranges comparable to conventional cars.

The centerpiece of electrolysis and fuel cells is the “Membrane Electrode Assembly” (MEA) which is primarily responsible for the performance and the durability. Hahn-Schickard develops additive manufactured high-performance MEAs and replaces the conventionally used membrane foil by a sprayed membrane (direct membrane deposition). The additional integration of nanofibers and/or nanoparticles enhances its chemical and mechanical stability significantly.
