1. An accelerated evaluation method for an anode, the method performing evaluation of durability of the anode in an accelerated manner by electrochemical operation in an aqueous electrolyte, and comprising:
a Je step of loading an oxidation current of 0.1 A/cm2 or more to the anode for a duration of Te; and
an Emin step of holding the anode at a constant potential lower than an open circuit potential for a duration of Tmin, wherein
each of the Je step and the Emin step is repeated 100 times or more.
