摘要： Disclosed are gas permeable 3D electrodes, preferably that have practical utility in, particularly, electro-energy and electro-synthetic applications. Gas permeable materials, such as non-conductive porous polymer membranes, are attached to one or more porous conductive materials. In another aspect there is provided a method for the fabrication of gas permeable 3D electrodes, for example gas diffusion electrodes (GDEs). The 3D electrodes can be utilized in electrochemical cells or devices.

摘要： A method and/or electrochemical cell for utilizing one or more gas diffusion 5 electrodes (GDEs) in an electrochemical cell, the one or more gas diffusion electrodes have a wetting pressure and/or a bubble point exceeding 0.2 bar. The one or more gas diffusion electrodes can be subjected to a pressure differential between a liquid side and a gas side. A pressure on the liquid side of the GDE over the gas side does not exceed the wetting pressure of the GDE during 10 operation (in cases where a liquid electrolyte side has higher pressure), and/or a pressure on the gas side of the GDE over the liquid side, does not exceeds the bubble point of the GDE (in cases where the gas side has the higher pressure).

摘要： 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.
