High-asymmetry bipolar membrane electrode assemblies generate a superconcentration of cations and hydroxide at a catalyst surface
A bipolar membrane generates ultrahigh pH (∼15) locally, achieving 93% selectivity for liquid products (ethanol/ethylene = 70 : 1) with 12× less crossover and long-term stability, advancing scalable electrosynthesis of carbon-neutral fuels.
