Abstract The influence of hot-pressing procedure on the performance of anodic half membrane electrode (AHME) used in direct liquid redox fuel cell (DLRFC) was investigated. The performance of DLRFCs activated by hot water circulation, constant current discharge and alternating current discharge were studied, respectively, to identify the optimal activation procedure. The dependence of the electrochemical properties of DLRFC on the process conditions of the constant current discharge activation was also studied. The results revealed that the optimal conditions for hot-pressing were being operated at 120 ℃ and under the pressure of 200 kg/cm2 for 120 s. Additionally, the discharge method was preferable to water circulation in activating DLRFC single cell. The activation of DLRFC by constant current discharge was optimized with the operating time, temperature and current density of 3 h, 60 ℃ and 20 mA/cm2, respectively.
