Abstract: A method of forming a bipolar separator assembly for use in a fuel cell assembly includes a step of forming an anode-side sub-assembly, which comprises sub-steps of: providing an anode current collector, providing a plate member, first and second opposing end segments and third and fourth opposing end segments, positioning said plate member so that said anode current collector abuts the first surface of the plate member, providing first and second anode wet seal members, and releasably securing the first and second anode wet seal members to the plate member; a step of forming a cathode-side sub-assembly, which comprises sub-steps of: providing a cathode current collector; providing first and second cathode wet seal members; and releasably securing the first and second cathode wet seal members to the cathode current collector; and a step of assembling the cathode-side sub-assembly with the anode-side sub-assembly.

Abstract: An assembly includes (a) an anode-side sub-assembly including: a plate member having first and second opposing surfaces compatible with fuel and oxidant gases, respectively, the plate member having first and second opposing end segments, and third and fourth opposing end segments; an anode current collector abutting the first surface of the plate member; and first and second anode wet seal members releasably secured to the plate member so as to form first and second pockets on the first surface of the plate member and (b) a cathode-side subassembly comprising: first and second cathode wet seal members configured to form third and fourth pockets on the second surface of the plate member and to be releasably positioned adjacent said third and fourth opposing end segments; and a cathode current collector cooperating with the first and second cathode wet seal members.

Abstract: A bipolar separator formed from a plate member and first, second, third and fourth pocket members separately formed from the plate member. The plate member is fabricated from a stainless steel material and each of the pocket members is fabricated from a stainless steel with an aluminum coating. Welds including aluminum affix the pocket members to the plate member.

Abstract: A bipolar separator formed from a plate having trough members formed on opposing first and second sides of a central area. Separately formed trough members are secured to opposing third and fourth sides of the central area. The trough members and trough areas are formed so as to reduce stress on the electrolyte matrices supported thereby.
