Abstract:Polymer-modified carbon paper was prepared by depositing aniline and thiophene monomers on the surface of anodic carbon paper using adopting the method of electrochemical polymerization, which was used as the anode to construct a two-compartment microbial fuel cell to study its electrical performance and the leaching of cathode cobalt. The results show that the maximum output voltages of polyaniline modified carbon paper and polythiophene modified carbon paper are 0.742V and 0.823V, which are 1.29 and 1.44 times of that of unmodified carbon paper, and the maximum power density are 14137.6 and 19360 mW/m2, which are 1.26 and 1.73 times of that of unmodified carbon paper, greatly improving the electricity production capacity. According to the leaching of cathode cobalt, carbon paper modified by polythiophene has the best effect, with coulomb efficiency, Co(Ⅲ) leaching rate and average leaching rate of 54.2%, 68.5% and 2.78 mg/(L·h), respectively, which are 1.33, 2.03 and 1.63 times of that of unmodified carbon paper.
