초록

본 연구에서는 3차원 전산유체역학 (3-D computational fluid dynamics, CFD)을 이용하여 고체고분자전해질형연료전지 (proton exchange membrane fuel cell, PEMFC)의 기체유로에 대한 성능에 관한 전산모사를 실시하였다. 또한 이 전산모사를 통하여 유체의 농도와 압력분포, 그리고 전류밀도의 분포 등 각종 분포에 관하여 연구를 진행하였다. 본 논문에서는 단일유로와 5개의 유로를 비교분석 하였다. 그 결과 5개의 유로가 단일유로에 비하여 각종 분포들이 균일하였고, 성능 또한 월등하였다. 특히 단일유로에서는 물질전달에의한 성능저하 영역에서 매우 낮은 성능을 확인할 수 있었고 반면 5개의 유로에서는 이 부분을 극복하여 보다 높은 성능을 확인할 수 있었다.

In this study, the performance and distribution of fluid concentration, pressure, and current density of a proton exchange membrane fuel cell was investigated. In this paper, the two different types of flow field design were compared, singel channel and 5-channels. As a result, the 5-channels of flow field showed the better performance than that of single chanel. Especially, the single channel showed better performance in terms of mass transfer loss area.
