Description
Xu and co-authors make, in 2026, a nanoporous zirconia composite membrane for alkaline water electrolysis, the workhorse route to green hydrogen. Zirconia membranes trade ion flow against gas tightness. Their one-pot sol-gel method disperses yttria-stabilized zirconia nanoparticles evenly through a polybenzimidazole matrix, with phosphoric acid bridging the phases. The result is a sponge-like membrane of about 85 percent porosity that still resists gas crossover.
Despite the openness, bubble-point pressure stayed above 25 bar, and the interconnected pathways let hydroxide ions migrate without pause. In electrolysis tests the membrane delivered a current density of 13.1 amperes per square centimeter at 2.0 volts, performance at the top of the field, and worked across a range of alkali concentrations. Reinforced with a polyphenylene sulfide mesh, it operated for 7,000 hours and scaled to a large-area single-cell stack. The authors present the route as scalable manufacturing for hydrogen production at scale.
