Abstract:
1. An electrochemical fuel cell stack, comprising at least one fuel cell assembly, wherein said fuel cell assembly comprises: a. an anode separator, comprising electrically conductive, non-metallic material, wherein said material is a carbon paper product that is highly porous and includes micro-channels, and further, wherein said anode separator comprises at least one fuel ingress and at least one means for fuel distribution from said fuel ingress to an anode flow field; b. a cathode separator, comprising electrically conductive, non-metallic material, wherein said material is a carbon paper product that is highly porous and includes micro-channels, and further, wherein said cathode separator comprises at least one oxidant ingress and at least one means for oxidant distribution from said oxidant ingress to a cathode flow field; c. a membrane electrode assembly interposed between said anode separator and said cathode separator, wherein said membrane electrode assembly comprises a proton exchange membrane interposed between an anode and a cathode; and d. a coolant separator interposed between said anode separator and said cathode separator, wherein said coolant separator comprises:
