Title:
ANODE CATALYST, WATER ELECTROLYSIS CELL, AND WATER ELECTROLYSIS CELL STACK
Document Type and Number:
WIPO Patent Application WO/2024/058162
Kind Code:
A1
Abstract:
This anode catalyst contains an oxide that has a perovskite structure which contains alkaline earth metal ions as A site ions, while containing metal ions (excluding iridium ions) and iridium ions as B site ions. With respect to this anode catalyst, the alkaline earth metal ions include strontium ions and the B site ions include at least tin ions, or alternatively, the alkaline earth metal ions include at least one kind of ions that are selected from the group consisting of calcium ions and barium ions.
