Enhanced bipolar membranes for durable ampere-level water electrolysis† Bipolar membrane (BPM) electrolyzers maintain a steady-state pH gradient, enabling optimal kinetics for electrode reactions. Traditional BPMs face issues with slow water dissociation (WD) kinetics and water transport limitations at high current densities, causing frequent failures during ampere-level electrolysis.

AbstractWhile Ru owns superior catalytic activity toward hydrogen oxidation reaction and cost advantages, the catalyst deactivation under high anodic potential range severely limits its potential to replace the Pt benchmark catalyst. Unveiling the deactivation mechanism of Ru and correspondingly developing protection strategies remain a great challenge.
