The Effect of Water Management and Cell Compression in Bipolar Membrane CO2 Electrolysis to CO
Carbon Energy, EarlyView.In‐operando neutron imaging uncovers water management challenges in bipolar membrane CO2 electrolysis: Internal water generation floods the cathode, while compression dictates membrane and gas diffusion electrode integrity. Strategic adjustments are applied in this work: dry gas feed and mechanical support of the gas diffusion electrode enable stable ...
