MODULAR FUEL CELL STACK ASSEMBLY INCLUDING ANODE GAS OXIDIZER AND INTEGRATED EXTERNAL MANIFOLDS FOR USE IN FUEL CELL STACK MODULES

摘要

A modular fuel cell stack assembly includes a plurality of fuel cell stacks each having a plurality of stack surfaces and a plurality of stack edges formed between the stack surfaces, A receiving structure for providing to the stack; Wherein the plurality of stack surfaces comprise a cathode inlet surface adapted to receive oxidant gas for use on the cathode side of the fuel cell stack, a cathode outlet surface adapted to discharge cathode exhaust from the cathode side, An anode inlet surface adapted to receive fuel for use on the anode side and an anode outlet surface adapted to discharge anode exhaust from the anode side, the cathode inlet surface, the cathode outlet surface and the anode inlet surface At least one of the anode exit surfaces is an open surface without a manifold and the receiving structure includes at least one sealed chamber for sealingly enclosing and isolating at least one of the open surfaces. A plurality of fuel cell stacks, and an anode exhaust from the fuel cell stack and using anode exhaust to generate oxidant gas and to center the fuel cell stack to distribute the oxidant gas to the fuel cell stack There is provided a modular fuel cell stack assembly including an oxidizer adapted to be adapted to receive the plurality of fuel cell stacks and oxidizers and to receive the fuel and distribute the fuel to the fuel cell stack.
