Beschreibung
Zusammenfassung:	The invention provides a desulfurizing agent which attains effective removal of sulfur from a hydrocarbon feedstock and/or an oxygen-containing hydrocarbon feedstock so as to attain a considerably low sulfur level and which has a long service life; a process for producing hydrogen for fuel cells, which process includes steam-reforming, partial-oxidation-reforming, or autothermal-reforming of a hydrocarbon feedstock and/or an oxygen-containing hydrocarbon feedstock which has been desulfurized by use of the desulfurizing agent; a fuel cell system employing hydrogen produced through the process. The desulfurizing agent for removing a sulfur compound from a hydrocarbon feedstock and/or an oxygen-containing hydrocarbon feedstock, the agent containing nickel, or a combination of nickel and copper, and silicon, and having a bulk density of 0.95 to 2.0 g/cm 3 , a pore volume of 0.10 to 0.40 mL/g, a micropore surface area of 100 to 250 m 2 /g, and an external surface area of 100 m 2 /g or less. The process for produci
