FIELD: power systems built around fuel elements. SUBSTANCE: system has first-medium compressor and electrochemical converter communicating with compressor that can receive first and second media. Converter is designed to conduct chemical reaction between first and second medium thereby producing electrical energy and outlet flow of chosen high temperature. Power system has in addition turbine communicating with electrochemical converter and used to receive converter outlet flow which is converted by mentioned turbine into rotary energy and electrical energy. System may be provided, in addition, with steam generator and steam turbine for electrical energy generation. Electrochemical converter is used in this case as substitute for combustion chamber or as fuel element replacing the combustion chamber. EFFECT: enhanced efficiency of power system. 72 cl, 9 dwg
