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

为了提高微生物燃料电池阳极的性能，研究了腐殖酸材料和氧化态金属作为催化剂的应用。与不含催化剂的阳极相比，含钨的碳布阳极显示出功率输出的两倍增加。含腐殖材料的碳布阳极的功率输出与不含催化剂的阳极的功率输出相当。Nafion溶液作为生物阳极催化剂的粘合剂对钨有效，而对腐殖物质无效。需要进一步开发使用腐殖材料的阳极催化剂。

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.
