Abstract: A method of forming a gas diffusion layer includes causing, at least in part, a stack of layers to be arranged between compressing surfaces of a press, the stack of layers including a plurality of gas diffusion layers. The method also includes causing, at least in part, the press to apply one or more compression cycles to the stack of layers to reduce a combined, uncompressed thickness of the plurality of gas diffusion layers between about 2% and about 30%.

Abstract: Aspects of the present disclosure provide a system for a carbon oxide electrolysis plant incorporating advanced electrochemical reactors incorporating membrane electrode assemblies as well as control mechanisms. The system provides efficient transport and production rates while minimizing the competing hydrogen formation reaction. The system may use multiple electrochemical reactors, scaling up production with high energy efficiency, while providing flexibility in the types of chemical product outputs.
