Abstract

A molten carbonate fuel cell, which is provided with an indirect internal steam reformer to efficiently control heat and simplify the system construction and has a simple structure to reduce production cost and efficiently controls heat to reduce operational cost and increase operational efficiency, is disclosed. The molten carbonate fuel cell of the present invention has a plurality of unit cells each including a porous matrix plate which is interposed between an anode plate and a cathode plate and is filled with an alkali carbonate electrolyte, the unit cells being stacked on top of another; at least one indirect internal steam reformer interposed between the stacked unit cells and reforming a fuel to hydrogen through a reforming reaction and supplying the hydrogen to the unit cells; a fuel manifold air-tightly installed at an inlet of both the indirect internal steam reformer and the unit cells and receiving a fuel supply pipe therein to supply the fuel to the indirect internal steam reformer; and a reformed fuel manifold air-tightly installed at an outlet of both the indirect internal steam reformer and the unit cells and supplying the hydrogen produced by the indirect internal steam reformer to the unit cells.
