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.

这项研究表明，固体氧化物电解槽的微通道阴极载体已得到开发，以改善CO ₂电解性能。通过嵌入载体中的许多通道，气体种类可以快速地扩散到阴极/电解质界面附近的反应区，或从中扩散出来，并且也可以实现催化剂向反应区的有效输送。研究了通道尺寸对CO ₂电解的影响，通道尺寸越小，气体扩散越快，电池电阻越低。因此，本研究报告了一种新的策略，可通过在网孔模板相转化过程中细化微通道结构来提高CO ₂电解性能。
