碩士 === 國立高雄應用科技大學 === 模具工程系碩士班 === 102 === PEMFC has to build in many of control mechanism in order to reach the best efficiency of fuel cell. As a result, this study attempts to investigate the heat dissipation and the phenomena of heat distribution in PEM fuel cell stacks. A three-dimensional computational model is developed with complete 300W of ten stacks of fuel cell to analyze the influence of different design of cooling methods to the heat distribution on fuel cell stacks by the tool of finite element method. At first, the study successfully compares the results of computational with experimental results for the sake of model’s accuracy and feasibility. The present results showed that number of fan and the distance of fan hood bring effects on the overall heat distribution on fuel cell. The two fans model has better effect on evened the heat distribution of fuel cell and less power consumption. But to a certain stage, the affection is almost the same with one fan model. Furthermore, the investigation against the short, medium and long distance of fan hoods, the results showed the longer the distance of fan hood, the better the heat distribution of fuel cell is more evenly. Finally, the numerical model and the design of mechanism of optimum temperature maintenance will provide related research in the future and then enhance the efficiency of fuel cell.
