ABSTRACT:
In a fuel cell power generation system for use with a fuel gas which is prepared by desulfurizing a raw fuel material such as naphtha, LPG, town gas, or the like and then, processing it by steam reforming reaction and thus, consists mainly of hydrogen or a process of producing the fuel gas, the desulfurization of the raw fuel material is implemented using a copper/zinc desulfurizing agent. As a result of the desulfurization, the raw fuel material is desulfurized at a higher level and the deterioration of a steam reforming catalyst employed is prevented. Accordingly, steady long-run operation of the fuel cell will be ensured. Also, upon the steam reforming reaction, the S/C (the mole number of steam per one mole of carbon in a raw fuel material) is reduced and thus, the concentration of hydrogen in the fuel gas will be increased providing an improvement in the efficiency of power generation.
