Redox electric couple species used in the catholyte of the hydrogen redox fuel cell was screened through the electrochemical testing methods, and the catholyte composition and concentration were optimized by studying the reaction mechanism and laws on different electrodes, then the inside battery structure was also designed. The results showed that when using the carbon felt as electrode, platinum as catalyst, ferric/ferrous ion solution as the most suitable catholyte optimal performance could be obtained. This method can reduce the cathode polarization and the amount of catalysts. It can also solve the problem of catalyst poisoning and membrane degradation, simplify water management, effectively reduce the costs and improve cell performance and reliability.
