本研究將開發直接甲酸燃料電池用的新穎含鈀合金陽極觸媒材料，首先以膠體先驅物法製作碳黑負載的高度分散化Pd 電極觸媒，探討觸媒製備方法、程序參數及前處理活化條件，對電極觸媒物理結構與電催化活性的影響，以得到Pd/C 電極觸媒製備的最佳化條件。再者，加入第二金屬成分製成鈀合金電極觸媒，探討其對甲酸分子的電催化氧化性能與耐CO 毒化的能力，以得到耐毒化含鈀合金電極觸媒的最佳成分和組成以及觸媒製備條件。本研究的結果將有助於開發含鈀合金實際應用為直接甲酸燃料電池的陽極觸媒材料。
This project is to develop a novel palladium-based alloy catalyst for the anode of a direct formic acid fuel cell. First, highly dispersed palladium catalysts on carbon will be prepared by the colloidal precursor technique. The effects of catalyst preparation methods, process parameters and activation conditions on the physical structure and the electrocatalytic activity of the catalyst will be studied. The optimal conditions for catalyst preparation will be identified. Moreover, Pd-based alloy catalysts will be prepared and their catalytic and CO-tolerant abilities for formic acid electro-oxidation will be evaluated. The best metal component and alloy composition of the Pd-based alloy catalyst and its optimal preparation conditions will be determined. The results of this research may contribute to the development of new palladium-based alloy anode catalysts for direct formic acid fuel cells.
