摘要： Electrochemical cells (e.g., fuel cells or electrochemical gas extraction cells) supplied with power-to-gas mixtures of dilute hydrogen concentrations may be remarkably improved by the use of porous gas layer electrodes. The electrochemical cells may comprise a first porous gas layer gas diffusion electrode, a second porous gas layer gas diffusion electrode, and a liquid electrolyte Sin contact with the first and second electrodes. The porous gas layers may each comprise a porous, non-conductive, liquid-impermeable material that dramatically improves cell performance.
