소형 고분자 전해질 연료전지의 성능향상을 위한 채널 형상의 개선 및 제작

다국어 초록 (Multilingual Abstract)

Recently, the interest on the development of fuel cell is growing rapidly . because, it is considered to be a novel form of power source to solve not only the environment problem but also drain natural resource problem. In this paper, hydrogen gas flow in micro-channel was numerically analyzed concerning about various channel shapes to estimate the efficiency of micro fuel cell. Each flow characteristic with the same boundary condition was simulated in each different shape (6-types) of micro-channels which have been already developed and newly designed as well. The result of analysis shows that characteristics of flow such as velocity, uniformity, and flow rate, depend highly upon the channel shape itself. That means it is expectable to increase the efficiency of micro fuel cell through optimal configuration of channel shape for hydrogen gas flow. Finally, actual micro flow channels were fabricated using SU-8 and the performance of PEM fuel cell was also carried out by these micro prototypes.
