Abstract
Various COx electrolyzer multi-cell architectures are provided, including various frame, flow field, gas diffusion layer, and repeat unit designs that may be particularly useful in the context of multi-cell COx electrolyzer cells.
Claims20
A COx electrolyzer apparatus (“apparatus”) comprising:
- a first end assembly;
- a second end assembly coupled to the first end assembly via a plurality of tensioning members;
- and
- a plurality of COx electrolyzer cells (“cells”) interposed between the first and second end assemblies and arranged in a stack along an axial direction, wherein each of the plurality of cells comprises:
- a cathode frame that defines a first opening;
- a cathode flow field at least partially disposed in the first opening;
- an anode frame that defines a second opening;
- an anode flow field at least partially disposed in the second opening;
- a first support frame;
- a second support frame;
- and
- a membrane electrode assembly (MEA) sandwiched between the first support frame and the second support frame, wherein the MEA is positioned between the cathode flow field and the anode flow field.
