摘要

In order to further improve the power density and output voltage of the battery, this paper introduces capacitive anode material to improve the output power of MFC. The most common pseudocapacitive materials mainly include metal oxides and conductive polymers. A rapid and reversible electrode reaction occurs in metal oxides, which usually occurs inside the electrode. Therefore, the theoretical capacitance of metal oxides is relatively large, which is several times that of carbon materials. Manganese dioxide (MnO_2) has been widely used as electrode materials for different batteries due to its high capacitance, good reversibility and low cost. Among conductive polymers, polyaniline (PANI) and polypyrrole (PPy) also have good conductivity, low price and high chemical stability. Therefore, based on the characteristics of polyaniline, polypyrrole and manganese dioxide, PANI/MnO_2/CC, PPy/MnO_2/CC and PANI/ PPy/ MnO_2/ CC hydrogel electrodes were prepared on CC substrates by in‐situ polymerization method, and applied as anodes to microbial fuel cell devices to study the power generation performance of the cells.
