Effects of the Methanol Concentration, Wind Velocity and Stack Temperature on the performance of Direct Methanol Fuel Cell

직접 메탄올 연료 전지의 성능에 대한 메탄올 농도, 풍속 및 스택 온도의 영향

DMFC(Direct Methanol Fuel Cell) has been considered as an attractive option to produce electric power in many application. In this study, in order to estimate the effects of the methanol concentration, wind velocity and temperature on the performance of DMFC, a physical prototype of DMFC was designed and manufactured, and the stack voltage of DMFC was measured during the operation of DMFC. Expecially, the experimental results showed that a low stack temperature, a low wind velocity and an excess methanol concentration lead to the increase of the time to reach the maximum stack voltage.
