Alkaline water electrolysers are being optimized for higher performance, but measures such as advanced electrodes or thinner separators can increase hydrogen crossover and safety risks. Here the authors analyse crossover behaviour and show that a gas recombination catalyst cuts crossover by 95% without affecting electrolyser performance.

We constructed cobalt porphyrin frameworks with precise N gradation to unveil the dual role of N: withdrawing electrons from Co sites and forming ordered hydrogen-bond networks to facilitate proton transfer, thereby boosting ORR kinetics.
