METHOD FOR USING CARBON-CONTAINING FUEL IN SYSTEM CONTAINING HIGH-TEMPERATURE FUEL ELEMENT Russian patent published in 2013 - IPC H01M8/04 

FIELD: power industry.

SUBSTANCE: system includes high-temperature fuel element; carbon-bearing fuel and converting reagent are placed in the converter. Endothermic reaction of carbon-bearing fuel with converting reagent is carried out in the converter. Mixture of CO and H₂ is obtained in converter, portions of mixture (CO and H₂) and oxidiser are supplied to anode and cathode respectively of high-temperature fuel element, which is the part of high-temperature oxidising system. The supplied portion of mixture is oxidised in high-temperature oxidising system with generation of electric and heat energy. Heat energy is transferred to converter; temperature is maintained in the converter in the range of 800-1300 K. Some part of H₂ is removed from the above mixture of CO and H₂, which is formed in the converter, and its amount supplied to high-temperature oxidising system is reduced. H₂ that has been removed from separation system is supplied to hydrogen utilisation system.

EFFECT: improvement of operating reliability of heat current source under conditions of action of high mechanical loads; invention allows increasing usability of carbon-bearing fuel in the system containing high-temperature fuel element, improving reliability and enlarging service life of high-temperature fuel element.
