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.

Abstract
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.File in questo prodotto:
