Title:
ANTI-CARBON-DEPOSITION SELF-SEALING ELECTRICITY-GAS SYMBIOTIC SOLID OXIDE FUEL CELL STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2024/061382
Kind Code:
A1
Abstract:
The present invention relates to the technical field of cells, and provides an anti-carbon-deposition self-sealing electricity-gas symbiotic solid oxide fuel cell structure. The cell structure comprises a connector reforming plate, an anode, an electrolyte, and a cathode, wherein the connector reforming plate comprises a connector body; an upper surface and a lower surface of the connector body are respectively provided with a cell supporting porous area and an oxidizing gas flow channel; a lower surface of the cell supporting porous area is provided with a reformed synthesis gas flow channel; a reforming porous area is provided between the reformed synthesis gas flow channel and the oxidizing gas flow channel, and the reforming porous area is separated from the upper and lower flow channels by leakage-free wall faces; and the anode, the electrolyte and the cathode are sequentially stacked on an upper surface of the cell supporting porous area. The cell structure realizes self-sealing of reformed fuel and reformed synthesis gas, thereby reducing the sealing difficulty for a flat-plate SOFC; and indirect reforming of fuel in the reforming porous area can prevent the problems of cell structure damage and anode carbon deposition caused by excessively high local thermal stress during internal reforming, thereby greatly improving the performance of a cell and prolonging the service life thereof.
