Inexpensive approach for coating bipolar plates for PEM fuel cells |
摘要 |
A metallic bipolar plate for use in a fuel cell includes a metallic bipolar plate having one or more channels and a contact surface. The contact surface has a surface roughness defined by a plurality of peaks and valleys wherein at least a portion of the valleys are filled with an electrically conductive material. The contact surface is adapted to contact the anode diffusion layer or the cathode diffusion layer such that the contact resistance occurring at this surface is lower than when the electrically conductive material is not present. A fuel cell incorporating the metallic bipolar plate is also provided.
