Preparation and Characteristics of LA_XSR_1-XCOO₃ as Cathode Catalysts for Microbial Fuel Cell

Microbial fuel cell (MFC) technology is a renewable resource, with the ability to treat sewage whilst simultaneously generating electricity. However, applications of MFCs have been limited by the low output voltage and power density. A key challenge to the commercialization of MFC is the need to develop steady, active, and cheap catalysts for an oxygen reduction reaction (ORR). As a result, developing new catalysts that do not contain the precious metal platinum – a scare commodity – has become an urgent matter. Oxide materials, like low-cost perovskites, are a promising electrocatalyst for cathodes in MFCs. The main purpose of this study was to find out the correlation between electricity generation in MFCs and electrocatalytic activity of particles in perovskite catalysts.
