Accelerated evaluation method for anode

Abstract

The present invention provides an accelerated evaluation method for an anode, the method imitating electric power having a large output fluctuation, such as renewable energy, and enabling an accurate evaluation, in a shorter time, of durability of an anode using such electric power having a large output fluctuation as a power source. The method is an accelerated evaluation method for an anode, the method performing evaluation of the durability of the anode in an accelerated manner by electrochemical operation in an aqueous electrolyte. The method includes 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 Train, wherein each of the Je step and the Emin step is repeated 100 times or more.
