Claim:
A method of fabricating a fuel reforming catalyst for a solid oxide fuel cell (SOFC) power generating system, comprising the steps of: (a) sintering γ-Al 2 O 3 in a high-temperature furnace provided with air under a temperature increasing rate of 5 Celsius degrees per minute (° C./min) to a temperature of 1080-1320° C. for a time period of 6-9 hours (hr); and, then, cooling down said temperature to room temperature under a temperature decreasing rate of 5° C./min to obtain a catalyst of α-Al 2 O 3 ; (b) dissolving Ce(NO 3 ) 3 .6H 2 O in de-ionized water to obtain a Ce(NO 3 ) 3 solution; (c) impregnating said catalyst of α-Al 2 O 3 with said Ce(NO 3 ) 3 solution; (d) taking surplus water from said Ce(NO 3 ) 3 solution containing said catalyst of α-Al 2 O 3 by a cyclotron vacuum concentrator to obtain CeO 2 /α-Al 2 O 3 ; (e) drying the CeO 2 /α-Al 2 O 3 in an oven; (f) sintering the CeO 2 /α-Al 2 O 3 in a high-temperature furnace provided with air under a temperature increasing rate of 5° C./min to a temperature of 440-660° C. for a time period of 3-5 hrs; (g) dissolving dihydrogen hexachloroplatinate in de-ionized water to obtain a platinum solution; (h) impregnating CeO 2 /α-Al 2 O 3 with said platinum solution; (i) taking surplus water out of said platinum solution containing CeO 2 /α-Al 2 O 3 by a cyclotron vacuum concentrator; and (j) sintering said platinum solution containing CeO 2 /α-Al 2 O 3 in a high-temperature furnace provided with air under a temperature increasing rate of 5° C./min to a temperature of 520-780° C. for a time period of 3-5 hr; and, then, cooling down said temperature to room temperature under a temperature decreasing rate of 5° C./min to obtain a catalyst of Pt/CeO 2 /α-Al 2 O 3 .
