摘 要

本研究的主要目的,在於進行具有開放式陰極之質子交換膜 燃料電池堆的研製以及進行相關的實驗測試與分析,藉以探討 其 陽極增濕溫度、螺栓扭矩、電池溫度以及陰極空氣流量等參數對 電池堆性能的影響。 研究結果顯示,燃料電池的組裝 和操作條件會影響其運轉性 能,尤其以陰極的空氣流量對電池性能的影響最為明顯。空氣流 量大時,雖可避免因空氣供 應不足而造成性能的降低;但相對地 ,空氣流量大到一定程度時,若再增大空氣流量,並無法提升電 池的性能,只會增 加燃料電池的寄生負載,假若能更進一步的瞭 解各負載下的最佳空氣流量,再配合流量控制系統的研發,維持 在最佳的 空氣流量,未來對燃料電池整體系統的發展將有很大的 助益。
