Abstract:
1. 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) an air supply system for controllably supplying air to said stack assembly; c) at least one heat exchanger disposed between said air supply system and said stack assembly and having a heated medium flowing through a first side thereof, wherein a first air flow from said air supply system is passed through a second side of said heat exchanger wherein said heated medium heats said first air flow, and a second air flow is bypassed of said heat exchanger, said first and second flows subsequently being controllably combined to provide air to said cathodes at a desired temperature.
