摘要

流化床微生物燃料电池(AFBMFC)的阴极导电性和催化剂性能是影响微生物燃料电池产电性能的重要因素。本文首先在阴极负载少量银研究其对AFBMFC产电性能的影响。其次

制备四种铂钴合金催化剂

考察了催化剂对AFBMFC产电性能的影响。研究表明

阴极碳基层负载少量的银可以显著改善AFBMFC的产电性能

银负载量为0.7 mg·cm-2时AFBMFC最大输出电压和输出功率密度分别为纯碳基层阴极的154%和330%。600℃比950℃制备的PtCo合金催化剂有较好的催化性能

在保证催化剂总量不变的情况下

铂用量为原来的50%

AFBMFC产电性能仍有较大幅度的提高。

Abstract

The conductivity of cathode and the activity of catalyst coated on cathode are critical to the electricity-generating capacity of AFBMFC.Carbon cloth cathode was loaded with a small amount of silver to investigate its influence for the conductivity of cathode.Then

four kinds of Pt/Co catalysts were prepared and coated to the cathode.The performance of AFBMFC was examined after the cathode was reformed.The results indicated that the performance of AFBMFC was improved remarkably when the carbon base layer was loaded with silver.With the addition of 0.7 mg Ag·cm-2

the maximum output voltage and volumetric power density of AFBMFC increased to 154% and 330% of the original values respectively.PtCo catalysts annealed at 600℃ showed higher catalytic activity than that annealed at 950℃. The power generation of AFBMFC was much higher than those investigated by other researchers

although the dosage of Pt was reduced to half.
