To investigate the impact of annealing conditions on electrolysis performance, annealed IrO2 powders are examined as anode catalysts in a high temperature polymer electrolyte membrane water electrolyzer (PEMWE). The IrO2 powders were annealed for from 1 to 8 hours under 350°C and 490°C. The effect of annealing time and temperature on the IrO2 phase, specific surface area of IrO2 and high frequency resistance (HFR) is investigated through analyzing the current-voltage (I-V) characteristics. The experiment result shows that annealing impacts on electrolysis performance majorly through changing IrO2 phase. Both lengthening annealing time and elevating annealing temperature change IrO2 phase from amorphous phase to crystal phase. The optimum annealing conditions is annealing IrO2 powder at 350°C for 1 hour.
