abstract = "Development of a durability protocol against the potential fluctuation derived by renewable energy is targeted in this paper. We have studied the effect of various potential fluctuations, by simulating practical operating conditions derived from the use of solar and wind powers. The durability of IrOi and the corresponding degradation mechanism were studied in order to suggest an appropriate durability protocol. We have found that relatively slow fluctuation without cycling back to the low potential like 0 V leads to serious degradation of IrOi catalyst. We have also investigated degradation mechanism of I1O2 and have found that IrOi is further oxidized to Ir02(OH) above 1.8 V, and then Ir02(OH) is converted into soluble Ir(OH)3 or InO} species, leading to loss of Ir02 electrocatalyst.",
