Abstract:
1. A molten carbonate fuel cell separator, comprising: a fuel electrode and an air electrode as electrode plates; a pair of mask plates for providing a seal between the pair of electrodes; current collectors for providing electrical connection with the electrode pair; and corrugated plates for inhibiting mixing of fuel gas, oxidant gas, and nitrogen gas, wherein the corrugated plates are composed of the fuel electrode corrugated plate for preventing mixing of hydrogen-containing fuel gas and nitrogen gas and the air electrode corrugated plate for preventing mixing of nitrogen gas and oxygen-bearing oxidant gas, and wherein fuel gas flows between the fuel electrode current collector and the fuel electrode corrugated plate through internal manifolds of the separator, oxidant gas flows between the air electrode corrugated plate and the air electrode current collector through internal manifolds of the separator, and nitrogen gas for cooling of a stack flows between the fuel electrode corrugated plate and the air electrode corrugated plate through an external manifold.
