SYSTEM OF FUEL ELEMENT AND METHOD OF ITS CONTROL Russian patent published in 2014 - IPC H01M8/04 H01M8/06 H01M8/12 

FIELD: power engineering.

SUBSTANCE: fuel element system comprises a fuel element (10), the first combustion chamber (20), the first check valve (17) for heating gas and a system (50) of gas supply. The fuel element (10) includes an element with solid electrolyte with an anode (12) and a cathode (13). The fuel element (10) produces energy by means of reaction of a hydrogen-containing gas and oxygen-containing gas. The first combustion chamber (20) selectively supplies heating gas to the cathode (13) of the fuel element (10). The first check valve (17) for heating gas mixes at least some of released gas exhausted from the cathode (13), with the heating gas of the first combustion chamber (20), so that the mixed heating gas from the exhausted gas and heating gas is supplied to the cathode (13). The gas supply system (50) is connected to the first check valve (17) for heating gas to supply exhausted gas from the cathode (13) so that it is mixed with the heating gas of the first combustion chamber (20).

EFFECT: increased efficiency of gas usage released from a cathode, by means of its usage for increasing temperature of a fuel element, and reduced deposits of carbon on an anode.
