Patent ID: 6942942

Claim:
A fuel cell system for generating electric power by combination of oxygen with hydrogen-containing fuel, comprising: a) a plurality of individual fuel cells organized into at least one fuel cell stack assembly including a plurality of cathodes and anodes; b) a reformer for reforming hydrocarbons to provide said fuel; c) an air supply system for supplying said oxygen in the form of air; d) an integrated fuel/air manifold for receiving said fuel from said reformer, conveying said fuel to said anodes, and returning said fuel as tail gas from said anodes, and for receiving said air from said air supply system, conveying said air to said cathodes, and returning said air from said cathodes; e) a thermal enclosure for housing at least one of said fuel cells, said reformer, or said manifold in a hot zone therein, wherein said thermal enclosure has a lower portion and an upper portion matably joinable along a split line; and f) a structural enclosure for housing said thermal enclosure and for housing said air supply system in a cool zone outside of said thermal enclosure.
