Development of microbial fuel cells using humic materials present in livestock wastewater

为了提高微生物燃料电池的生物阳极性能，研究了腐殖质材料和氧化金属作为催化剂。与不含催化剂的阳极相比，含钨的碳布阳极的功率输出增加了两倍。含有腐殖质材料的碳布阳极的输出功率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较好的吸附效果，而对腐殖质材料的吸附效果较差。利用腐殖质材料进一步开发阳极催化剂是有必要的。

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.
