Abstract

To increase energy output and reduce the cost of MFC, an air-cathode single chamber MFC containing carbon electrodes without proton exchange membrane (PEM) was developed. Power generation from domestic wastewater, glucose, acetate, and butyrate (main by-products of hydrogen fermentation) was examined. The power density was 55-400% higher than that in the MFC containing PEM, reaching 146 mw/sq cm using domestic wastewater, 494 mw/sq cm using glucose, 506 and 305 mw/sq cm using acetate and butyrate, respectively, which were much greater than typically reported for aqueous-cathode MFC. The increase in power output was attributed to the direct oxygen transfer to the carbon cathode and the elimination of overpotential caused by PEM. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA 8/22-26/2004).
