摘要

这项工作提出了一种焦耳加热策略来制造具有高质子导电性和低H2交叉的薄质子交换膜（PEMs）。经过处理的PEMs组装的电解槽在1.9 V时达到3.72 a cm−2的电流密度，在2 a cm−2的电解条件下具有1250小时的耐久性。

Thermal-shock-processed thin proton exchange membranes for efficient and durable water electrolysis with reduced hydrogen crossover

This work presents a Joule-heating strategy to create thin proton exchange membranes (PEMs) with high proton conductivity and low H₂ crossover. The treated PEMs assembled electrolyzer achieves a record current density of 3.72 A cm⁻² at 1.9 V with 1250 h durability at 2 A cm⁻² for water electrolysis.
