Power generation using a low-cost sulfated zirconium oxide based cathode in single chamber microbial fuel cells

Innovative and cost effective electrode materials to be used as cathodes in lab-scale MFC prototypes were prepared from mixtures of commercial Platinum on Vulcan (Pt/C) and sulfated zirconia (SZrO2). The catalytic activity of the SZrO2 based catalysts towards the oxygen reduction reaction (ORR) was studied by cyclic voltammetry (CV) and linear sweep voltammetry (LSV), showing comparable electrochemical activity between a mixture with one half of...
