The fuel cell power plant operates at higher reactant pressures, and thus higher power density (lower cost) and efficiency, by providing reactant reformer steam (42) from a separate steam boiler (42). Instead of supplying coolant steam to the reformer, the coolant is operated in a closed loop apart (10, 12) from the reformer (46), and the coolant steam is used to drive a steam generator (20, 22) to produce additional electricity. A portion of the raw fuel (40) is burned within the steam boiler and the remainder is passed through the reformer and thence to the fuel cells (2). Boiler exhaust (64) is used to drive a turocompressor (62) which pressurizes the air (30) used on the cathode side (6) of the fuel cells. |
