To improve bioanode performance in microbial fuel cells, humic materials and oxidized metals as catalysts were investigated. The carbon-cloth anode containing tungsten showed a twofold increase in the power output, as compared to an anode without catalyst. The power output of the carbon-cloth anode containing humic materials was comparable with that of the anode without catalyst. A Nafion solution as the binder for bioanode catalyst was effective against tungsten, while it was not effective against humic materials. Further developments of anode catalyst using humic materials are required.

为了提高微生物燃料电池的生物阳极性能，研究了腐植酸材料和氧化金属作为催化剂。与不含催化剂的碳布阳极相比，含钨碳布阳极的功率输出增加了一倍。含有腐植酸材料的碳布阳极的功率输出与不含催化剂的阳极相当。Nafion溶液作为生物阳极催化剂的粘结剂对钨有效，而对腐殖质无效。利用腐植酸材料进一步开发阳极催化剂是必要的。
