Abstract
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.
