Abstract: The off-line accelerated stress tests were used to conduct the electrochemical corrosion of gas diffusion layer for different hours, and the effect of the electrochemical corrosion time on the oxygen transport resistance of gas diffusion layer was evaluated by limiting current methods. The results show that the dry region of gas diffusion layer is narrower, and the oxygen transport resistance increases significantly after electrochemical corrosion. When the relative pressure is 150 kPa and the oxygen mole fraction is 21%, the oxygen transport resistance values of gas diffusion layer after 48 h and 72 h electrochemical corrosion increase by approximately 61.82 s/m and 95.62 s/m, respectively. The morphology of the gas diffusion layer was studied by scanning electron microscopy (SEM). The reason why the water management ability of gas diffusion layer decreases after electrochemical corrosion was analyzed by SEM image and contact angles.
