| 英文摘要 | the carbon-supported pt-modified au nanoparticles were prepared by two different chemical reduction processes, the simultaneous chemical reduction of pt and au on carbon process (a-aupt/c) and the successive reduction of au then pt (b-aupt/c) on carbon process. these two catalysts were investigated as the anode catalysts for a direct borohydride fuel cell (dbfc) and au nanoparticles oil carbon (au/c) were also prepared for comparison the dbfc with b-aupt/c as the anode catalyst shows the best anode and fuel cell performance the maximum power density with the b-aupt/c catalyst is 112 mw cm(-2) at 40 degrees c, compared to 97 mw cm(-2) for a-aupt/c and 65 mw cm(-2) for au/c. in addition, the dbfc with the b-aupt/c catalyst shows the best fuel utilization with a maximum apparent number of elections (n(app)) equal to 6 4 in 1 m nabh(4) and 7 2 in 0 5 m nabh(4) as compared to the value of n(app) of 8 for complete utilization of borohydride.
