Description

Technical Field

[0001] The invention belongs to the field of carbon dioxide electrolysis cells, and in particular relates to a pressure distribution detector for a carbon dioxide electrolysis cell. Background Art

[0002] Using renewable energy to electrocatalytically reduce carbon dioxide into useful fuels and chemicals under mild and controllable conditions is an important frontier in energy chemistry with broad application prospects. The core challenge is to develop high-performance electrocatalysts for the carbon dioxide reduction reaction (CO2RR) and devices for realizing electrocatalytic reactions, thereby increasing the yield of the target product and achieving high selectivity.

[0003] At present, it is impossible to detect the pressure distribution in the carbon dioxide electrolysis cell. The pressure in the reaction device has an impact on the degree of reaction. In reality, there are few pressure detection devices in the reaction device.
