本研究主要是利用電沉積的方式共鍍Pd、Ni製備出Pd-Ni二元金屬薄膜以提升Pd薄膜作為直接乙醇燃料電池中觸媒層對於乙醇電氧化的效能。實驗中主要是藉由不同的電沉積參數，如電位和電量等條件來調控Pd、Ni含量比例，探討Pd-Ni薄膜中不同Pd、Ni比例對於乙醇電氧化的效能之影響。實驗中我們另外嘗試添加錯合劑硫氰酸鉀和三乙醇胺以改善未添加錯合劑時所製備出的Pd-Ni薄膜之缺點，進而提升乙醇電氧化的最大效能。
在實驗中，我們發現添加錯合劑三乙醇胺有最佳的錯合效果，其製備出來的Pd-Ni薄膜在較高Pd含量組成比例時有最佳的乙醇電氧化電流密度126.5 mA/cm2，同時添加三乙醇胺也能大幅度的提高在Pd含量低於80%時的乙醇電氧化電流密度。

The performance of ethanol electro-oxidation on Pd thin film as a catalyst layer in direct ethanol fuel cell (DEFC) can be promoted by co-electrodeposition of Pd-Ni alloy thin film. In this study, we investigated the effect of Pd and Ni composition on ethanol electro-oxidation through the modulation of different parameters of electrodeposition such as potential and column. In this study we extraly use complexes, potassium thiocyanate (KSCN) and triethanolamine (TEA) to improve the defects of Pd-Ni alloy thin films produced without complex and advanecdly to promote the maximum performance of ethanol electro-oxidation.
In this study, we found that high Pd amount composition of the Pd-Ni film with TEA, which has the best function of complexity, owns the best maximum current density of Jp = 126.5 mA/cm2 on ethanol electro-oxidation. Meanwhile, the films produced with complex TEA promote the performance of ethanol electro-oxidation even when composition of Pd is less than 80%.
