METHOD FOR OPERATING INDIRECT INTERNAL REFORMING SOLID OXIDE FUEL CELL SYSTEM

摘要

Disclosed is a method for operating an indirect internal reforming solid oxide fuel cell (SOFC) system that can maintain the temperature of a reformer in a stable and proper manner. The method for operating an indirect internal reforming solid oxide fuel cell system comprising a reformer with a reforming catalyst layer for producing a reformed gas from a hydrocarbon fuel, a solid oxide fuel cell that generates electric power using a reformed gas obtained in the reformer, and a combustion region for burning an anode off gas discharged from the solid oxide fuel cell. The reformer is disposed at a position that can receive combustion heat generated in a combustion region. The method comprises the step of regulating the temperature of the reforming catalyst layer by varying a power generation output value of the solid oxide fuel cell.
