Abstract

Flooding of gas diffusion electrodes (GDEs) used in electrochemical conversion of CO₂ to ethylene is caused by polymerization of minor products. The polymer so created reduces the hydrophobicity of the GDE, leading initially to a reduction in the ethylene yield and finally to complete failure.
