수소이온 교환막 전도도에 따른 성능 변화를 반영한 3차원 HT-PEMFC 모델 개발

초록

Recently, sustainable and eco-friendly technologies have become essential due to climate change and the depletion of fossil fuels. For this reason, interest in fuel cells, a technology that produces energy without emitting carbon, is increasing, and among them, research on proton exchange membrane fuel cell (PEMFC) with high energy efficiency is actively underway. However, there is a limitation in that conducting trial-and-error-based repetitive experiments is economically burdensome because the Pt/C catalyst, which constitutes these cells, is very expensive. To address this, research on governing equation-based multiphysics simulations, which analyze performance using computers, is actively being conducted. While multiphysics simulations can be performed from one dimension (1D) to three dimension (3D), the limitations of each dimension are clear, requiring clarification. Through preliminary research, our research group performed 1D and 2D analyses based on high-temperature proton exchange membrane fuel cell and demonstrated that flow rate optimization is possible in 2D. In this study, we extend this to fabricate a 3D model based on a high-temperature proton exchange membrane fuel cell and examine the differences from the 2D model.
