为了解决全球日益增长的能源需求，需要一种可持续且环保的能源。微生物燃料电池（MFC）作为一种以废物为原料的可持续绿色生物能源转换技术具有巨大潜力。这项工作致力于开发一种有效的小型 MFC，用于从尿液中产生能量。开发了一种创新的空气阴极微型 MFC，并研究了电极长度的影响。还研究了两种不同的生物质衍生催化剂。电极长度加倍导致功率密度增加一个数量级（从0.053 W m(-3) 到0.580 W m(-3)）。当三个设备并联时，功率输出比单个设备高出 10 倍以上。在阴极使用生物质衍生的氧还原反应催化剂将MFC产生的功率密度提高至1.95 W m(-3)，从而证明了可持续催化剂对于MFC中阴极反应的价值。 (C) 2016 年作者。由爱思唯尔有限公司出版
To resolve an increasing global demand in energy, a source of sustainable and environmentally friendly energy is needed. Microbial fuel cells (MFC) hold great potential as a sustainable and green bioenergy conversion technology that uses waste as the feedstock. This work pursues the development of an effective small-scale MFC for energy generation from urine. An innovative air-cathode miniature MFC was developed, and the effect of electrode length was investigated. Two different biomass derived catalysts were also studied. Doubling the electrode length resulted in the power density increasing by one order of magnitude (from 0.053 to 0.580 W m(-3)). When three devices were electrically connected in parallel, the power output was over 10 times higher compared to individual units. The use of biomass-derived oxygen reduction reaction catalysts at the cathode increased the power density generated by the MFC up to 1.95 W m(-3), thus demonstrating the value of sustainable catalysts for cathodic reactions in MFCs.
