Title:
FUEL CELL DEVICE, AND METHOD FOR OPERATING FUEL CELL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/189844
Kind Code:
A1
Abstract:
The purpose of the present invention is to obtain a high-efficiency fuel cell in which an internal reforming reaction is logically and effectively used even when an anode electrode layer provided to a fuel-cell cell is on the order of several tens of microns. The present invention comprises a fuel-cell cell in which an anode electrode layer and a cathode electrode layer are formed sandwiching an electrolyte layer, a reducing-gas-supply path via which a hydrogen-containing gas is supplied to the anode electrode layer, and an oxidizing gas supply path via which an oxygen-containing gas is supplied to the cathode electrode layer. A fuel-cell single cell unit U having an internal reforming catalyst layer comprising a reforming catalyst that performs water-vapor reformation of a fuel gas is provided in at least part of the reducing-gas-supply path. An external reformer 34 comprising a reforming catalyst that performs water-vapor reforming of the fuel gas is provided upstream from the reducing-gas-supply path. Partially reformed fuel gas is supplied by the external reformer 34 to the reducing-gas-supply path.
