Solid oxide fuel cell system and its operating method

Abstract

There are provided an SOFC system using kerosene as a reforming raw material, the SOFC system being capable of effectively cooling the cell and capable of being stably operated with no decreased efficiency, and an operating method thereof. The solid oxide fuel cell system includes reforming means for reforming kerosene to obtain a reformed gas, a methanation catalyst layer disposed downstream of the reforming means and capable of promoting a methanation reaction, cooling means for cooling the methanation catalyst layer, and a solid oxide fuel cell disposed downstream of the methanation catalyst layer. The operating method of a solid oxide fuel cell system includes reforming kerosene to obtain a reformed gas, performing a methanation reaction to increase a methane amount in the reformed gas, and supplying a gas obtained in the methanation to a solid oxide fuel cell.
