Abstract Fuel Cell Stack with Combination End-Pressure Plates In place of the conventional thick graphite end plate, steel pressure plate combination at the ends of a fuel cell stack, a single steel end plate is used at each end. Each steel end plate is coextensive with the fuel cell component plates and the end plates are held in place by corner brackets mating with insulated tie rods, a load cable is connected directly to the end plates, and gas manifolds sealingly engage the vertical side surfaces of the end plates with a seal which resists unseating due to thermal growth differences between the component parts of the stack. A sealing plate to provide electrical continuity is interposed between the steel pressure plate and the adjacent cell component plates.
