초록

A hydrogen fuel cell power system having improved efficiency comprises a fuel cell, a source of hydrogen gas, a compressor for creating a pressurized air stream, and a liquid supply which is heated by waste heat form the power system and evaporates into the pressurized air stream to produce a pressurized air and steam mixture. The pressurized air/steam mixture, which is preferably used as the oxidant in the fuel cell, is combusted with fuel in a burner to produce a high-temperature steam-laden exhaust stream. The high-temperature steam-laden exhaust stre...
