摘要

本研究的為開發鋅空氣燃料電池( Zinc-Air Fuel Cell, ZAFC)，首先針對電池芯中的鋅陽極，空氣陰極及電解液製作與參數測試，如鋅陽極利用不同壓合壓力及燒結溫度、空氣電極利用不同PTFE配比等，討論其參數改變對電池性能差異，接著設計、開發單電池，並針對單電池性能:開迴路電壓、VI曲線，定電流放電，不同功率放電、單電池連續五次放電，單電池收放及更換電解液等測試，後續再將單電池組立完成電池模組進行測試，由實驗結果得知，鋅陽極結構在壓合壓力及不同燒結溫度在 200 kg/cm2、350℃時其性能為較佳；而空氣電極最佳配比在擴散層PTFE含量40%且催化層 PTFE 含量在 10 至 20 % 間；單電池在長時間放電測試中性能達 45 Wh，90 Wh/kg ，在重複放電測試五次，其工作時間在 10 小時以上；電池模組長時間放電測試達 18 小時，電池模組性能達 103 Wh/kg，在模組串聯測試中，其工作時間在 17 小時以上。

The purpose of this research is development of zinc air fuel cell battery. First, the cell marking is the key point in development process, and that is mainly to establish the excellent manufacture parameters of anode, cathode and electrolyte by experimental analyses in cell performance. There are series of works are provided including single cell design, cells assembly design, performance analysis. The open current voltage test, long term constant voltage discharge test, long term constant watt discharge test, continuity supply anode fuel discharge test, and continuity fill electrolyte discharge test of the single cell performance of were measured. Finally, set up the ZAFC modules and test in this study. According to the test, the better performance of zinc anode is when pressure and temperature are controlled in the 200 kg/cm2, 350 ℃. The best PTFE ratio of the diffusion layer is 40% and catalyst layer is between 10 to 20 %. Single cell discharge performance is 90 Wh / kg. Module discharge test is up to 18 hours, and the module performance is 103 Wh / kg. The repeated discharge test in five times, the working time is up to 10 hours or more.The module series test, working time is up to 17 hours.
