Minor Product Polymerization Causes Failure of High-Current CO2‑to-Ethylene Electrolyzers
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.
