透氣袋式鋅空氣燃料電池之設計與開發
Design and development of bag type zinc-air fuel cell
摘要
本研究主要目的在提升鋅空氣燃料電池的能量密度。因此，從減輕單電池整體重量與提升單電池性能兩方面著手，在減輕單電池重量方面，主要使用透氣袋加上邊框來達到輕量化的目的，由於透氣袋本身為袋狀，只需在其外邊利用細長條的框架來支撐極可達到減輕重量的目的；提升性能方面則是改善鋅陽極粒徑的分佈與空氣陰極催化劑的更換，進而達到提升能量密度與功率密度的目的。 在電池性能的測試部分，本研究主要針對單電池性能進行開迴路電壓、PVI曲線、以及電容量測試，最後再設計電池模組，再將多顆電池模組進行放電測試。由實驗結果得知：當鋅陽極粒徑分佈由3μm ~ 35μm範圍縮小到4μm ~ 12μm範圍之後，可使其電容量提升約50%；更換空氣陰極催化劑可使其工作電流從 57 mA 提升至106 mA，性能約提升50%；單電池在性能測試結果中電容量可達 51 Wh，能量密度可達145.7 Wh/kg。

The main purpose of this study is to improve the energy density of the zinc-air fuel cell. Therefore, from a single battery performance lighten the overall weight of the single cell and upgrading two aspects. In reducing the weight of the single cell to add borders to achieve the purpose of lightweight breathable bags. Breathable bag itself as a pouch, just at its outer framework to support the use of elongated strips of poles can reach a weight reducing purposes. Enhance performance is to reduce zinc anode the particle size distribution and the replacement of the air cathode catalyst , and thus achieve the purpose of enhance the energy density and power density. Then the battery module discharge test. The experimental results show that: When the zinc anode particle size distribution by 3μm ~ 35μm to 4μm ~ 12μm range, its electric capacity upgrade by about 50%. Replacing the air cathode catalyst to enhance its operating current from 57 mA to 106 mA, Performance increased to about 50%. Single battery electric performance test results a capacity of 51 Wh, energy density up 145.7 Wh/kg.
