Abstract Alkaline water electrolyzer (AWE) is widely considered as an environmentally‐friendly technique for green H 2 production. However, it still a great bottleneck that the AWE technology cannot meet fluctuating renewable energies, due to instability and poor resistant counter‐current property of electrocatalysts in AWE. Herein, high‐stable robust WMo‐CoP@NM electrocatalyst constructed by modulating electronic structure CoP catalysts. The catalyst not only exhibits excellent hydrogen evolution reaction (HER) performance at ampere‐level current densities, but also presents outstanding adaptability multi‐cycle start‐stop tests AWE, which offers opportunity use energies produce . Importantly, (cathode)||NM (anode) holds ultra‐long stability over 1500 h 30 wt.% KOH 65 °C, confirms their potential practical applications. DFT calculation shows synergistic effect Mo W doping can increase adsorption capability optimize species, therefore efficiently promote HER performance. In short, this work provides first example via designing catalysts realize will accelerate coupling with
