摘　　要：试验以泡沫镍材料作为空气阴极MFC的电极材料，并利用碳粉作为催化剂，在1．24A／m2的电流密度下获得了214mW／m2的最大功率密度输出。电位分析结果表明，阴极开路电位为＋12mV，阳极开路电位为-466mV。采用改变外阻的调节方式，获得了18．6％～57．8％的库伦效率。试验结果表明，碳粉可以作为催化剂材料在泡沫镍基体空气阴极MFC系统中使用。The foamed nickel material was used carbon dust as catalyst, a maximum power output as electrode material of air cathode MFC, and of 214 mW/m2 was obtained when current density was 1.24 A/m2, The results of potentiometric analysis showed that when open circuit potential of cathode and anode were ＋12 mV and -466 mV respectively. Coulomb efficiency was achieved 18.6% -57.8% by changing external resistance. The test results showed that powered carbon could be used as catalyst in air cathode MFC system with foamed nickel material as matrix.
