Electrochemical power supply design and parts

摘要

A bipolar plate comprises: a first corrosion resistant layer having a plurality of vias formed therein, each via extending through the first corrosion resistant layer and being filled with an electrically conductive, corrosion resistant material; a second corrosion resistant layer having a plurality of vias formed therein, each via extending through the second corrosion resistant layer and being filled with an electrically conductive, corrosion resistant material; a conductive metallic core having a first primary surface in electrical contact with the material in the vias of the first corrosion resistant layer and a second primary surface in electrical contact with the material in the vias of the second corrosion resistant layer; the material in the vias being different from the material forming the conductive metallic core, the first corrosion resistant layer, and the second corrosion resistant layer.
