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 Jstep of loading an oxidation current of 0.1 A/cmor more to the anode for a duration of Tand an Estep of holding the anode at a constant potential lower than an open circuit potential for a duration of T, wherein each of the Jstep and the Estep is repeated 100 times or more.
