단위전지 적층수 변화에 따른 연료전지 냉각판의 성능 특성에 대한 수치해석적 연구

Fuel cell is one of the promising power generation devices to cope with the increasing of the energy consumption and the environmental pollution. Recently, PEM(Polymer electrolyte membrane) fuel cell has been developing vigorously as a small fuel cell system such as automobiles and portable devices. An appropriate temperature control of the PEMFC is very important to get higher performance and reliability. Therefore, the fuel cell stack is composed of MEA and cooling-plate. In this study, the performance of the cooling-plate with a serpentine channel for the fuel cell stack was analyzed according to the ratio of the number of unit cells to the cooling-plate, which was changed from 1 to 5. The cooling performance of the cooling-plate with the ratio of 1 to 1 was more enhanced than it of the others. But, it is also need to consider the compactness of the system in the actual systems.
