POWER SUPPLY PLANT BASED ON SOLID OXIDE FUEL CELLS Russian patent published in 2018 - IPC H01M8/06 H01M8/12 

FIELD: electricity.

SUBSTANCE: invention relates to power supply plant based on solid oxide fuel cells for power and heat co-generation, using hydrocarbon fuel and intended for local consumers, as well as to units and batteries based on fuel cells used in standalone and backup power supply plants. The power plant based on solid oxide fuel cell contains a subsystem of preparation and processing of fuel, a power production subsystem with a fuel cell battery, air and water subsystem, an exhaust gas post-processing subsystem, while the power production subsystem consisting of unified modules containing a solid oxide fuel cell stack, an anode gas heat exchanger-recuperator, a cathode gas heat exchanger-recuperator, associated with an additional subsystem of primary heating by means of a line for the supply of combustion products, which leave the excess heat and are diverted to the post-processing subsystem.

EFFECT: reduction of energy costs during the start-up phase of the power plant with increasing reliability and simplification of maintenance and repair of the plant.
