Microbial fuel cells produce significant lower power output than conventional hydrogen and oxygen powered fuel cells. Thus, the utilization of fuel cell-grade materials is not practical in microbial fuel cells for recovering energy from wastewater. Air cathode single chamber microbial fuel cells are cost effective and relatively high power output. In addition, the cathode was the major contributor in the total cost of microbial fuel cells. In this paper, we reviewed the latest literatures that report metal-free oxygen reduction catalysts, binders and gas diffusion layers. Based on the recent progress, a perspective was given to design an effective air cathode in single chamber microbial fuel cells.
