英文摘要: This study has demonstrated that microchanneled cathode supports of solid oxide electrolysis cells were developed to improve CO2 electrolysis performance. Through numerous channels embedded within the support, gas species can diffuse quickly to/from the reaction zone near the cathode/electrolyte interface, and efficient catalyst delivery to the reaction zone can also be achieved. The effect of channel size on CO2 electrolysis was investigated, and the smaller channel size results in the faster gas diffusion and the lower cell resistance. Therefore, this study reports a new strategy to improve CO2 electrolysis performance via refining the microchannel structure during a mesh-templating phase-inversion process. © 2018 Published by Elsevier Ltd.
