SOLID-STATE OXIDE FUEL CELL SYSTEM Russian patent published in 2008 - IPC H01M8/12 H01M8/06 

FIELD: high-temperature fuel cells.

SUBSTANCE: proposed system of solid-state oxide fuel cells has set of solid-state oxide fuel cells and gas-turbine engine. Set of solid-state oxide fuel cells has plurality of solid-state oxide fuel cells, each incorporating electrolyte, anode, and cathode. Gas-turbine engine has compressor and turbine. Compressor is designed to feed oxidant to cathode. There are means for feeding fuel to anode and means for feeding part of unused oxidant from solid-state oxide fuel cells to cathodes. Facility for feeding at least oxidant has combustion chamber and ejector. Combustion chamber is designed to burn at least part of unused fuel coming from solid-state oxide fuel cells and to feed its products of combustion to oxidant supplied by compressor to cathodes for heating compressor-fed oxidant.

EFFECT: enhanced effectiveness of fuel cell system.
