摘　　要：液相催化燃料电池可以直接利用有机物并产电,是一种处理生物质废物的新途径。为了进一步提高现有电池的性能,本研究针对阳极催化剂进行了混合催化研究,对阴极催化剂进行了比选优化,最后对优化后的电池处理葡萄糖、淀粉和蛋白质的性能分别进行了测试。结果表明:(1)在葡萄糖和磷钼酸浓度一定时,阳极添加0.5 mol/L FeCl3后性能最好,最大功率密度达到5.9 mW/cm^2;(2)在阴极催化剂中,HPA-73p杂多酸性能虽然稍差,但是其稳定性好于HPA-82p,因此更适于LCFC体系;(3)优化后的LCFC处理葡萄糖、淀粉和蛋白质时最大功率密度分别达到6.5、1.9和1.8 mW/cm^2,并且对于越难处理的有机物,FeCl3的加入对LCFC提升效果越明显。Liquid catalyzed fuel cell （LCFC） can directly use organic matter to generate electricity, and it is a new way for utilization of biomass waste. To prompt the existing LCFC, mixed anode catalysts were proposed, cathode catalysts were compared and selected, and finally an optimized LCFC was built. Its performance using glucose, starch and protein as the fuels was further tested. The results showed that： （l） When the concentrations of glucose and phosphomolybdic acid were fixed, the performance was the best with the addition of 0.5 mol/L FeCl3, and the maximum power density reached 5.9 mW/cm2; （2） At cathode, HPA-73p heteropolyacids was more stable than HPA-82p despite the former＇s performance was a little lower; （3） When the optimized LCFC was used to treat glucose, starch and protein, the maximum power density reaches 6.5, 1.9, and 1.8 mW/cm2, respectively, and the influence of the added FeCl3 on LCFC was more significant when the organic substance was more difficult to degrade.
