In this project, first, the electrochemical behavior of iridium oxide and ruthenium oxide catalysts made in Iran and ruthenium oxide catalysts manufactured by Merck as well as equal mixtures of iridium and ruthenium oxide (manufactured by Merck) during cyclic voltammetric tests, Linear scanning voltammetry; electrochemical impedance and chronoamperometry were investigated. Test Results of Equally Mixed Catalysts of Iridium and Ruthenium Oxide (Merck) was selected as the catalyst suitable for use as the anode cell electrolysis with proton exchange membrane. Subsequently, the proton exchange membrane electrolyzers were designed and fabricated with the desired characteristics. The activation of PEMWE was performed in three separate stages. and then the polarization test at different inlet temperatures and fluorites for temperature selection and optimum fluorite was obtained. According to the results of polarization tests of 80 ° C and 5 ml/min, inlet water was selected as optimum temperature and fluorite. Then, at this temperature and fluorite inlet water, the stability test was performed in two constant voltages of 1.6 volts and 1.9 volts for 720 minutes. From the results of the PEMWE, it can be seen that the catalyst used is highly capable of being used in proton exchange membrane electrolyzers, and it is also made extensively useful for industries that require high purity hydrogen and oxygen.
