Search for: [Abstract = "In this work, the electricity production from yeast wastewater in membrane\-less microbial fuel cells with a carbon felt, Ni\-Co, Cu\-B, and Cu\-Ag cathodes has been analyzed. In the first place, the measurements of the stationary potential of the electrodes \(with Cu\-Ag catalyst obtained by the electrochemical deposition technique\) were performed. Next, the analysis of the electric energy production during the operation of the membrane\-less microbial fuel cell \(ML\-MFC\)."]
