FUEL CELL SYSTEM

摘要

Disclosed is a technology regarding a fuel cell system. An embodiment of the present invention provides the fuel cell system which comprises the following: a fuel supplier; a catalyst combustor combusting fuel supplied from the fuel supplier; a fuel reformer reforming the fuel using combustion heat generated from the combustion of the catalyst combustor as a heat source; and a fuel cell stack preheated by the combustion heat generated from the combustion of the catalyst combustor, and making the reformed fuel react to produce power.
