Abstract
A direct fuel cell was constructed by taking anaerobic activated sludge as the initial inoculums. The maximum voltage of 590 mV (1000 Ω) was achieved after inoculating for 160 h. The effects of different substrate and catalyst on the cell performance were investigated. The results show that the maximum power density of glucose (669 mW/m2) is larger than that of butane diacid (235 mW/m2). In comparison with the electrode potential, the anode potential changes more as the function of external resistance, which is mainly due to a difference in the mixed strains ability of different substrates consumption, and it can choose a suitable electricigens to improve the electricity production performance of butane diacid. In addition, taking manganese as the cathode catalyst instead of platinum, the maximum output of which is 147 mW/m2, and it has a certain gap to the result of the platinum and needs to further optimize the catalyst proportion and preparation methods.
