Abstract The focus of microbial fuel cell research in recent years has been on the development of materials, microbes, and transfer of charges in the system, resulting in a substantial improvement in current density and improved power generation. The cathode is generally recognized as the limiting factor due to its high-distance proton transfer, slow oxygen reduction reaction (ORR), and expensive materials. The heterogeneous reaction determines power generation in MFC. This comprehensive review describes-recent advancements in the development of cathode materials and catalysts associated with ORR. The recent studies indicated the utilization of different metal oxides, the ferrite-based catalyst to overcome this… More >

Abstract A methodology of on-line monitoring of the diameter of the cathode electrode is put forward in light of the issue that the diameter of the cathode electrode cannot be detected in an accurate manner in short electric arc machine tools. The monitoring methodology is capable of precisely determining the wear amount of the cathode electrode and uses the bus module in the numerical control machine tool to feed the wear amount of the cathode electrode back to the numerical control system (CNC system). The CNC system dynamically adjusts the position of the cathode electrode by driving the compensation shaft to… More >

Abstract Water flooding in the cathode is considered as one of the most important factors that impede the performance of direct methanol fuel cells (DMFCs) during the operation of high current density. Therefore, it is essential to study water management of cathode in DMFC. In this work, a two-dimensional, steady-state, two-phase, mass-transport model of DMFC with micro-porous layer (MPL) was developed considering methanol crossover and water crossover processes. Emphasis is placed on investigating parameter design of cathode to relieve flooding in DMFC, further to improve cell performance. The effects of MPL parameters, including porosity and thickness, on water distribution in cathode… More >
