Abstract

A fuel cell power plant for producing electricity uses pressurized air and fuel in the cells. The air is compressed by compressor apparatus powered by waste energy in the form of hot pressurized gases including hot pressurized steam produced by the power plant. In one embodiment the compressor apparatus includes a turbine operably connected to a compressor, and hot pressurized gases produced by the power plant flow into the turbine thereby driving the compressor. The steam is generated by heat from the fuel cells, passes through the fuel cells adjacent the cathode electrode thereof, and is delivered into the turbine along with the other gases.
