Abstract
An electro-synthetic water electrolysis cell, and method of operation, including a first gas diffusion electrode configured to generate a first gas and be in direct contact with a first gas body including the first gas, and a second electrode. A porous capillary spacer is configured to be filled with a liquid electrolyte and is positioned between the first gas diffusion electrode and the second electrode. Preferably, an average pore diameter of the porous capillary spacer is more than 2 μm (microns).
