摘　　要：以石墨碳棒为阳极,面状石墨碳毡为阴极,构建新型单室微生物燃料电池,并与传统单室结构进行对比,考察反应器结构对P-MFC产电性能的影响,并以翠芦莉、灰莉、鸢尾3种观赏类植物作为植株选种进行实验,比较其产电性能,分析植株生理机制与产电性能的关系,结果表明:新型反应器的性能是传统结构产电性能的2~3倍,最大输出功率密度由5 095 m W·m^(-2)增加到1 5198 m W·m^(-2),而且以翠芦莉构建P-MFC产电性能较优,最高电压为0.943 V,最大功率密度可达19.761 W·m^(-2),为植物微生物燃料电池的应用提供一定的理论依据。A new single-chamber microbial fuel cell was constructed with graphite carbon rods as the anode and faceted graphite carbon mats as the cathode,and was compared with the traditional single-chamber structure to investigate the effect of reactor structure on the power production performance of P-MFC,and three kinds of ornamental plants,Ruellia brittoniana Leonard,Fagraea ceilanica Thunb and Iris tectorum Maxim,were used as plant selections for experiments to compare their power production performance and analyze the relationship between plant physiological mechanisms and power production performance.The results showed that the performance of the new reactor was 2~3 times higher than that of the conventional structure,and the maximum output power density increased from 5095 mW/m^(-2) to 15198 mW/m^(-2).Moreover,the power generation performance of the P-MFC constructed by Ruellia brittoniana Leonard is better.The maximum voltage is 0.943 V and the maximum power density can reach 19.761 W/m^(-2).The investigation provides some theoretical basis for the application of plant-microbial fuel cells.
