Abstract
A gas diffusion electrode for an electro-synthetic or electro-energy cell, for example a fuel cell, including one or more gas permeable layers, a first conductive layer provided on a first side of the gas diffusion electrode, and a second layer, which may be a second conductive layer, provided on a second side of the gas diffusion electrode. The one or more gas permeable layers are positioned between the first conductive layer and the second layer, which may be a second conductive layer, and the one or more gas permeable layers provide a gas channel. The one or more gas permeable layers are gas permeable and substantially impermeable to the liquid electrolyte. The porous conductive material is gas permeable and liquid electrolyte permeable. The gas diffusion electrode can be one of a plurality of alternating anode/cathode sets.
