고분자전해질형 연료전지스택의 적층에 관한 연구 II

As the output voltage from unit cell of PEMFC is very too low voltage to use in real life, so the fuel cell is used through connecting the multiple cells. But there is a shortage of various studies about combination of PEMFC stacks. In this study, two types of the PEMFC stacks were chosen. Those are laminated stack and non-laminated parallel stack. The performance of the two types of the combinations of the PEMFC stack was measured on different flow rate of reaction gases each other. As the result, the performance of a laminated stack was higher than the performance of non-laminated parallel stacks because of difference of electric resistance caused connecting cells.
