質子交換膜燃料電池(PEFC)具有能量密度高、容易起動與關機、壽命長等優點,是現今低溫燃料電池中,最有發展潛力的一種燃料電池。它適合使用於電動車輛、筆記型電腦、行動電話等裝置,無疑地它將會成為未來主要行動電力的來源。質子交換膜燃料電池的『水管理』對其性能影響甚大,若『水管理』做得好則燃料電池的效率與性能就會較佳,因此『水管理』是質子交換膜燃料電池的關鍵技術之一,本論文即在於探討燃料電池的『水管理』的相關問題。
本研究建構了一個質子交換膜燃料電池的數學模型,並依據此一數學模型發展出一電腦模擬程式,該電腦模擬程式即用以模擬燃料電池的運轉。燃料電池的運轉過程中,質子交換膜含水量的變化、陰極水份泛溢的情形,皆在探討之列。此外,利用陽極除水法將陰極的積水移除,以減少陰極的氧氣質傳阻礙,提升燃料電池的性能,亦是本論文的探討重點。
With the merits of high energy density, easy to start and shutdown, longevity, polymer electrolyte fuel cell (PEFC) is the most prospective one among low-temperature fuel cells. PEFC fits for the use on electric vehicle, laptop computer, cellular phone, and it goes without saying that PEFC will become very popular in the near future. “Water management” is closely related to the performance of PEFC. Good water management ensures higher efficiency and good performance. So water management is one of the crucial technologies of PEFC. The present research is about the water management of PEFC.
The objectives of this research are to construct a mathematical model of PEFC and to set up a computer code for simulation. This computer code was then used to simulate the operation of a PEFC. The variation of water content in the PEM and the flooding in the cathode were investigated. In addition to that, the improvement of PEFC performance by applying the technique of anode water removal was studied.
