FUEL CELL AND METHOD FOR PRODUCTION THEREOF

摘要

The invention relates to a fuel cell which has a membrane-electrode unit comprising an ion-conducting membrane with catalyst layers which are disposed on oppositely situated surfaces of the membrane and serve as anode and cathode, and also possibly an anode-side and/or a cathode-side gas diffusion layer, the membrane-electrode unit having adjacent regions with different diffusion transport for educts and/or products. The invention likewise relates to a method for the production of fuel cells of this type.
