Abstract
An object of the present invention is to provide an electrolysis technique such that the electrolysis performance is unlikely to be deteriorated, and excellent catalytic activity is retained stably over a long period of time even when electric power having a large output fluctuation, such as renewable energy, is used a power source, and this object is realized by an alkaline water electrolysis method, in which an electrolytic solution obtained by dispersing a catalyst containing a hybrid cobalt hydroxide nanosheet (Co-NS) being a composite of a metal hydroxide and an organic substance is supplied to an anode chamber and a cathode chamber that form an electrolytic cell, and the electrolytic solution is used for electrolysis in each chamber in common, and an alkaline water electrolysis anode.
