Co-based non-precious group metal oxide electrocatalysts were synthesized for the oxygen evolution reaction using co-precipitation, electro-deposition method, and so on. These catalysts were subsequently applied as anode electrodes in an anion exchange membrane water electrolyzer. We easily and creatively developed nano-sized Co-based oxide catalysts with abundant oxygen vacancies, large electrochemical surface area, morphology control, and electronic modification by using several synthesis methods. As a result, the catalyst demonstrated superior catalytic activity and long-term stability in half-cell tests. Recent reports have mainly focused on the catalytic activity of electrocatalysts in half-cell tests. However, it is crucial for electrocatalysts to exhibit excellent performance in full cells to achieve commercial viability. The AEMWE cell's performance surpassed that of any previously reported AEMWE cells, even when compared to those using IrO2 as an anode catalyst.
