摘要： 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 J e step of loading an oxidation current of 0.1 A/cm 2 or more to the anode for a duration of T e and an E min step of holding the anode at a constant potential lower than an open circuit potential for a duration of T min , wherein each of the J e step and the E min step is repeated 100 times or more.

摘要： The present invention realizes industrially excellent effects such that when electric power having a large output fluctuation, such as renewable energy, is used as a power source, electrolysis performance is unlikely to be deteriorated and excellent catalytic activity is retained stably over a longer period of time, and in addition, the present invention provides a technique that enables forming a catalyst layer of an oxygen generation anode, which gives such excellent effects, with a more versatile materials and by a simple electrolysis method. Provided are an alkaline water electrolysis method including supplying an electrolyte obtained by dispersing a catalyst containing a hybrid nickel-iron hydroxide nanosheet (NiFe-ns) being a composite of a metal hydroxide and an organic substance to an anode chamber and a cathode chamber, and using the electrolyte for electrolysis in each chamber in common, an alkaline water electrolysis method including supplying an electrolyte obtained by dispersing a catalyst containing the NiFe-ns to an anode chamber and a cathode chamber, and performing electrolytic deposition of the NiFe-ns in the electrolytic cell during operation to electrolytically deposit the NiFe-ns on a surface of an electrically conductive substrate having a catalyst layer formed on a surface of an oxygen generation anode, thereby recovering and improving electrolysis performance, and an alkaline water electrolysis anode.
