摘要: The present invention provides an alkaline water electrolysis anode such that even when electric power having a large output fluctuation, such as renewable energy, is used as a power source, the electrolysis performance is unlikely to be deteriorated and excellent catalytic activity is retained stably over a long period of time. The alkaline water electrolysis anode is an alkaline water electrolysis anode 10 provided with an electrically conductive substrate 2 at least a surface of which contains nickel or a nickel base alloy and a catalyst layer 6 disposed on the surface of the electrically conductive substrate 2, the catalyst layer 6 containing a nickel-containing metal oxide having a spinel structure, wherein the nickel-containing metal oxide contains nickel (Ni) and manganese (Mn), and has an atom ratio of Li/Ni/Mn/O of (0.0 to 0.8)/(0.4 to 0.6)/(1.0 to 1.8)/4.0.

摘要: The present invention provides an electrode for electrolysis in which electrolysis performance is hard to deteriorate and excellent catalytic activity is kept stable over a long period of time even when electric power in which there is a large fluctuation in output, such as renewable energy, is used as a power source. The electrode for electrolysis is an electrode 10 for electrolysis provided with an electrically conductive substrate 2 at least the surface of which contains nickel or a nickel-based alloy, an intermediate layer 4 formed on the surface of the electrically conductive substrate 2 and containing a lithium-containing nickel oxide represented by composition formula LixNi2-xO2 (0.02≤x≤0.5), and a catalyst layer 6 of a nickel cobalt spinel oxide, an iridium oxide, or the like, the catalyst layer 6 formed on the surface of the intermediate layer 4.
