摘要: 为研究铁氰化钾对双室微生物燃料电池(MFC)阴极性能的改善效果,以碳毡和碳棒作为复合电极材料,乙酸钠为阳极电子供体,分别以氧气、铁氰化钾和氧气交替作为阴极电子受体.通过测定使用铁氰化钾作阴极电极液之前和之后的曝气阴极MFC的功率密度及极化曲线,比较曝气阴极MFC的内阻、开路电压(OCV)和最大输出功率的变化情况.实验结果表明,当以铁氰化钾作为MFC阴极电子受体时,MFC的内阻、开路电压和最大输出功率分别为24.2 Ω、744.2 mV和33.7 W/m3.曝气阴极MFC在采用铁氰化钾作电极液对阴极性能进行改善之前和改善之后的内阻由77.2 Ω降低到40.1 Ω,OCV和最大输出功率分别由517.9 mV和2.1 W/m3提高到558.2 mV和4.4 W/m3.研究表明,铁氰化钾本身不仅具有优良的接受电子的能力,而且对电极材料(碳毡和碳棒)的电化学性能具有明显的改善作用,使得使用铁氰化钾之后的曝气阴极MFC的产电性能有了明显且持久性的提高.

Abstract: In order to study the improvements of potassium ferricyanide on the performances of cathode in a double chamber microbial fuel cell (MFC),carbon felt and carbon rod were taken as the composite electrode materials, sodium acetate was used as the electron donor in the anode of the MFC, and the electron acceptor in the cathode of the MFC were potassium ferricyanide and oxygen respectively. Before and after potassium ferricyanide was used as the electron acceptor in the cathode of the MFC, variations of the internal resistances, the open circuit voltage (OCV) and the maximum output power were determined. The results indicated that when potassium ferricyanide was the electron acceptor in the cathode of the MFC, the internal resistances, the OCV and the maximum output power were 24.2 Ω、744.2 mV and 33.7 W/m3, respectively. After the aeration cathode of the MFC was improved by potassium ferricyanide electrode solution, the internal resistances decreased from 77.2 Ω to 40.1 Ω, the OCV increased from 517.9 mV to 558.2 mV, and the maximum output power increased from 2.1 W/m3 to 4.4 W/m3. Potassium ferricyanide has an excellent electron acceptance ability, and can improve the electro-chemical performances of electrode materials (carbon felt and carbon rod) obviously. After the use of potassium ferricyanide, the electricity generation performance of the aeration cathode of the MFC was improved significantly and durably.
