| 초록 | Since the implementation of 2050 carbon neutral, many studies have been focused on the CO2 conversion. The CO2 electrolysis is one of the solutions for carbon neutral, which can be used for electrochemical reduction of CO2 and production of renewable energy. Membrane electrode assembly (MEA) plays an important role in reaching high current density for CO2 electrolysis. Specifically, the ion-transfer rate in membrane affects the current density, which can vary depending on various parameters. Therefore, it is important to analyze the effect of each parameter in MEA. However, there are scarcity of studies on parameter estimation for CO2 electrolysis. To address this limitation, the MEA model is developed using multi-physics simulation, which is implemented to measure current density and faradaic efficiency depending on various operation conditions such as temperature, pressure, and relative humidity. It is observed that the performance of MEA is affected by various operating conditions, but particularly affected by the relative humidity in membrane. Our study suggests a generic framework to estimate the parameters affecting the performance of electrolysis system. |
