The increasing cost of precious metals, especially platinum, as oxygen reduction catalysts impede their widespread use in microbial fuel cells for practical application. It is therefore of importance to develop alternative catalysts based on nonprecious metals. Electrochemical results revealed that cobalt oxide incorporation increased the ORR activity of cobalt phthalocyanine adsorbed on carbon particles. When applied to MFCs, the maximum power density of 780 mW m-2 was achieved with the C-CoOx-CoPccathode, which was about 50 % higher than that with carbon supported CoPc. The voltage output of the MFC dropped only 19 % from its initial voltage after 100 days’ operation, suggesting that the synthesized catalyst showed enough long-term stability. The voltage drop was partially resulted from the covering of biofilm on the catalyst layer, 89~92 % of which was reinstated upon scrapping off the biofilm. This work shows that C-CoOx-CoPc could be a potential alternative to Pt in MFCs for sustainable energy generation.
