摘要: The carbon-supported Pt-modified Au nanoparticles were prepared by two different chemical reduction processes, the simultaneous of Pt and on carbon process (A-AuPt/C) successive then (B-AuPt/C) process. These catalysts investigated as anode for a direct borohydride fuel cell (DBFC) oil (Au/C) also comparison DBFC with B-AuPt/C catalyst shows best performance maximum power density is 112 mW cm(-2) at 40 degrees C, compared to 97 A-AuPt/C 65 Au/C. In addition, Catalyst utilization apparent number elections (N(app)) equal 6 4 in 1 M NaBH(4) 7 2 0 5 value N(app) 8 complete borohydride. (C) 2009 Elsevier B.V. All rights reserved.
