Measurement and Numerical Simulation of Temperature Distributions of a Microtubular SOEC during H_2O/CO_2 Co-electrolysis

摘要

Co-electrolysis by SOEC can generate CO and H_2 from both CO_2 and H_2O at the same time. For practical use of SOEC, it is important to know temperature distributions, which affect the durability of the cell. In this study, temperature distributions of air electrode surface were measured by a thermal imaging camera to understand the temperature distribution in SOEC during co-electrolysis. Additionally, the temperatures were measured directly at three points by K-type thermocouples for comparing the temperatures measured by the camera. Furthermore, a two dimensional numerical model of a SOEC was developed and compared to the measured temperature distributions.
