Gas Diffusion Electrode

Electrochemical Converter

A gas diffusion electrode, or GDE, is an electrode built around a three-way junction of solid, liquid and gaseous phases, carrying an electrically conducting catalyst that supports an electrochemical reaction between the liquid and the gas at that junction. This structure lets a gas reactant, such as hydrogen or oxygen, reach the catalyst and react efficiently at the electrode surface, which is why gas diffusion electrodes are a standard component of fuel cells and other electrochemical devices that consume or produce a gaseous species.
