    • 題 目：金屬發泡材流道應用於直接硼氫化鈉-過氧化氫燃料電池

    本研究主要探討金屬發泡材應用於直接硼氫化鈉-過氧化氫燃料電池(Direct Sodium Borohydride – Hydrogen Peroxide Fuel Cell, DBFC)之適用性，並以流道進出口的壓降以及電池性能做為探討依據。
    研究使用自行設計之電池進行實驗；第一部分以測量進出口的壓降結果，對流道特性的了解與分析；第二部分將操作參數設定在流道形式與陽極硼氫化鈉濃度，並試圖測試出最佳之電池性能表現。
    其結果顯示，將金屬發泡材應用於陽極流道有助於提升電池性能，其電池性能皆大於傳統的蛇形流道；針對發泡材孔隙大小不同的探討中，孔隙大的發泡材壓降較低，代表其流場結構阻力較小；孔隙小的發泡材有較佳的燃料分佈；針對塗佈PTFE與否之發泡材討論中，孔隙大的發泡材適合利用此方法提升電池性能，其塗佈後有助於氫氣的排除以及燃料均勻度的提升；孔隙小的發泡材並不適用此方法，因塗佈後會使孔隙過小，影響燃料傳輸；實驗得到電池的最佳效能為單電池18W的功率輸出。

    The main purpose of this study is to investigate the metal foams as a flow passage in the direct sodium borohydride – hydrogen peroxide fuel cell (DBFC) based on the pressure drop and the performance of the single cell. First, the measurement of the pressure drop of different flow channels was performed. Second, we set the experimental parametric values for the different flow channels and different concentrations of borohydride in anode, and tried to find the best performance of a single cell.
    The result reveals that the performance is improved by using the metal foam as the flow passage. The performance of metal foams are better than that for the serpentine one. In the study of the effect of different sizes of metal foams, it is found that a larger pore size results in a lower pressure drop because of less resistance moreover. A smaller pore size results in a uniform flow distribution in the reaction area. In the study of the effect of metal foams coated with /without PTFE, a larger pore size is appropriate for coating PTFE on metal foam. It can enhance the removal of the hydrogen production and produce the uniform flow distribution in the reaction area. A smaller pore size is not appropriate for this way. It will greatly reduce the average of pore size after coating PTFE. Experimental result indicated that the maximum power achieved 18 W respectively.
