A study on improving the current density performances of CO₂ electrolysers.

ABSTRACT: Electrochemical CO₂ reduction reaction (CO₂RR) technology can reduce CO₂ emission with converting excess electrical energy to high-value-added chemicals, which however needs further improvement on the electrolyser cell performance. In this work, extensive factors were explored in continuous CO₂ electrolysers. Gold, one of the benchmark materials for CO₂RR to produce CO, was used as the catalyst. Electrolyser configurations and membrane types have significant influences on cell performance. Compact MEA-constructed gas-phase electrolyser showed better catalytic performance and lower energy consumption. The gas diffusion electrode with a 7:1 mass ratio of total-catalyst-to-polytetrafluoroethylene (PTFE) ionomer exhibited the best performa
