Ultra-high efficiency combination of turbine and fuel cell (57) Summary

A turbine power system comprising a compressor (76) for compressing a first medium, and an electrochemical converter (72) in communication with the compressor and adapted to receive the first medium and another medium. The converter is designed to allow an electrochemical reaction between the first and second media, thereby generating electricity and producing exhaust gas having a selected high temperature. The power system further comprises a turbine 80 in fluid communication with the electrochemical converter (72) and adapted to receive the exhaust gas of the converter so that the turbine converts the exhaust gas of the electrochemical converter to rotational energy and electricity. The system can further comprise a steam generator and a steam turbine that produces electricity.
