current density in a membrane electrode assembly (MEA) electrolyzer demonstrates minimal activity decay (< 3%). Density functional theory (DFT) calculations demonstrate that self-healing mechanisms optimize intermediate adsorption and electron distribution. This strategy enables efficient muti-electron transfer processes under industrial conditions, working to improve the stability of single-atom catalysts and develop scalable catalytic systems.
