本研究藉由調控電鍍製程之輔助電解質種類、分散劑濃度、前驅物濃度、脈衝式電沈積循環次數，以及基材親水前處理之循環次數，作為優化鉑觸媒的手段。我們使用熱化學沈積法在氣體擴散層表面成長奈米碳管，作為觸媒之基材。經過優化後的觸媒，可在1 x 1 cm2的電極面積中，得到最佳之電池輸出功率為817 mW/cm2；搭配ICP-MS結果可以得知在1 x 1 cm2的電極面積上，鉑觸媒的承載量為1.04 mg，其單位質量之鉑觸媒輸出功率為785 mW/mgPt。此一優化後的觸媒擁有較高的催化活性，較商用觸媒相比展現較少之活性極化過電位，並且在單電池之單位電極面積輸出功率高於商用觸媒電池。
在電極面積放大的電鍍製程中，我們將根據1 x 1 cm2電極面積的電鍍製備參數進行2 x 2 cm2的電鍍製程優化研究。在優化電沈積製備參數以及單電池測試條件後，目前2 x 2 cm2電極面積的最佳化參數可得到最佳之電池輸出功率為780 mW/cm2。

In this research, Pt catalysts were improved by conditioning the species of supporting electrolyte, the molarity of precursor, the adding of disperser, the repeat cycle count of pulse-potential for Pt deposition process and the cycle count of hydrophilic pretreatment. At electrode area of 1 x 1 cm2, the Pt loading was 1.04 mg/cm2, and we gained the 817 mW of power output from a single cell after the optimization of fabrication process. Compared to the commercial catalysts, the homemade electrodeposition catalysts had higher catalytic activity and caused less activation polarization.
For electrode area of 2 x 2 cm2, we optimized the Pt electrodeposition process and the condition of single cell test, the best power output was 780 mW/cm2.
