The influence of water impurities caused by 3d-block metal ion dissolution on proton exchange membrane (PEM) water electrolysis was investigated. While Co²⁺ and Ni²⁺ significantly decreased membrane conductivity, MnO₄⁻ anions exhibited a negligible effect. As MnO₄⁻ had low affinity for perfluorosulfonic acid in the PEM, Mn oxides materials have promising potential for use in PEM water electrolyzers.

溶解的 3d 嵌段金属离子对 PEM 电解水性能的影响


研究了 3d 嵌段金属离子溶解引起的水杂质对质子交换膜 （PEM） 电解水的影响。虽然 Co²⁺ 和 Ni²⁺ 显着降低了膜电导率，但 MnO₄⁻ 阴离子表现出的影响可以忽略不计。由于 MnO₄⁻ 在 PEM 中对全氟磺酸的亲和力较低，因此 Mn 氧化物材料在 PEM 水电解槽中具有广阔的应用潜力。
