BATTERY OF SOLID OXIDE FUEL CELLS Russian patent published in 2016 - IPC H01M8/12 H01M8/1253 

FIELD: engines.

SUBSTANCE: invention relates to the battery of solid oxide fuel cells which consists of an air supply unit including a flange with a nozzle with a calibrated washer, an air flow spreader, a central flange with holes for installation of tubes with seals for air supply into fuel elements; heat exchange chamber with heat exchanger in the form of a cylinder made of porous material with axial channels and with tubes installed with a gap to feed air into fuel elements, a screen, a catalytic afterburner for residual fuel containing porous material covered with a catalyst in made in the form of tubular grating with open ends of fuel elements fixed in it and air supply tubes passing through. Chambers of electrochemical oxidation of fuel with fuel elements closed ends of which are directed toward reactor of partial oxidation of primary fuel with air, are fixed relative to the body by means of a ceramic flange with recesses and with channels for fuel supply from the reactor of partial oxidation of primary fuel with air. Reactor of partial oxidation of primary fuel with air is made in the form of disk made of porous material covered with a catalyst. Unit for supply of mixture of primary fuel with air including top flange with nozzle with a calibrated washer and cylinder with axial channel ending with diffuser is made of heat-insulating material and provides lowering of operating temperature of primary fuel. Higher efficiency of electrochemical generator based on solid oxide fuel cells is the technical result of the invention.

EFFECT: fuel utilization factor in the battery comes up to 85 %.
