A system and method for producing electricity with a fuel cell power system. The power system includes an assembly of fuel cell stacks (220) that operate at different temperatures, which vary between two or more of the fuel cell stacks. The fuel cell stack can have multiple temperature regions (240, 242, 244) formed axially along the stack, or a plurality of spatially separated fuel cell stacks can be employed to heat a reactant from an input temperature to a desired temperature. The fuel cell stacks have operating temperatures in the range between about 20 DEG C and about 2000 DEG C. |
