PURPOSE:To attain a reformation ratio of about 100% even if the temperature of reformation is lowered, by providing an external and an internal reformers. CONSTITUTION:In a complex-reformation fuel cell power generation equipment, fuel is reformed by an external reformer 8 and an internal reformer 7 provided in the anode chamber of the equipment. If the equipment is of the molten carbonate type and operates at a temperature of 650 deg.C, the operation temperature of the external reformer 8 is set about 650 deg.C to reform about 60$ of the initial fuel therein (the ratio of reformation is about 60%), and the rest of the fuel is reformed by the internal reformer 7 in the anode chamber of the equipment, namely, about 40% of the initial fuel is reformed by the internal reformer, so that the ratio of reformation of all the fuel is about 100%. The operation temperatures of he external and the internal reformers can thus be made lower so that the reforming reaction load on reforming catalysts is reduced. This results in lengthening the total life of the reformers.
