A system for generating electricity comprises a fuel cell, a heating stage, and an integral, power generator. The power generator comprises a compressor, an electricity generator and a turbine. Hot exhaust gas from the fuel cell is used for driving the turbine, which in turn drives the generator and the compressor. Both the fuel cell and the generator produce electricity. The compressor is used for compressing air for use in the fuel cell. A portion of the waste heat from the turbine drive gas is used for preheating the air utilized in the fuel cell.
[ What is claimed is:] [1.] A process for generating electricity utilizing an integral, power generator comprising a compression stage, an electricity generation stage, and a turbine stage all on the same shaft, the process comprising the steps of:(a) compressing an oxygen-containing gas in the compression stage;(b) heating at least some of the compressed gas in a heating stage;(c) introducing fuel and the compressed heated gas into a fuel cell for oxidizing the fuel therein to produce electricity, the fuel cell also producing hot exhaust gas;(d) driving...
