Abstract

A fuel cell system includes: a reformer to generate a fuel gas from a raw material gas, reforming water, and air supplied to the reformer; an SOFC to generate electric power through a power-generating reaction by utilizing the fuel gas and air; a combustor to combust an anode off gas discharged from the SOFC; a hot module housing the reformer, the SOFC, and the combustor, which are covered with a heat insulating material; and a hydrodesulfurizer to remove a sulfur component from the raw material gas by hydrodesulfurization. The anode off gas is supplied to the combustor and the hydrodesulfurizer in a distributed manner. The hydrodesulfurizer performs the hydrodesulfurization of the raw material gas by utilizing the anode off gas as a hydrogen source and utilizing an exhaust gas discharged from the hot module as a heat source, the exhaust gas containing at least combustion heat from the combustor.
