燃料電池被視為具發展潛力的潔淨能源之一。本研究藉自製白金觸媒並應用於質子交換膜燃料電池中，探討不同操作條件及流道板設計下對其效能的影響。白金觸媒之製備是以奈米碳管為擔體，採用乾式含浸法 (dry impregnation) 將碳管含浸於氯鉑酸 (dihydrogen hexachloroplatinate (IV) hexahydrate) 溶液中，再以硼氫化鈉 (sodium borohydride) 還原。製備的觸媒以 XRD、SEM、TEM 等儀器進行特性分析。
將觸媒配成漿料塗佈於 50% 疏水碳紙上，與 Nafion® 117 熱壓成膜電極組 (membrane electrode assembly, MEA) 後，即進行單電池系統測試。藉由改變操作參數 (電池操作溫度、流量、陰極氧氣進料濃度、鎖合扭矩等) 及流道板設計 (開孔率、流道樣式等)，以燃料電池的極化曲線 (V-I curve) 與功率曲線 (P-I curve) 的結果作為電池性能的依據。
實驗結果顯示，陰極供應高濃度氧氣、增加陽極氫氣與陰極空氣流量，可提升單電池性能；不同流道面積會影響開孔率，當開孔率太高會減少其電子收集效果，而開孔率太低會使觸媒無法充分利用，在63% 的性能最好。最後，蛇形流道不易在陰極堆積水而有較小的擴散阻抗，使得蛇形流道的性能優於平行流道。透過本研究，以空氣作為氧化劑，所得到最佳參數之最大功率為176.3 mW/cm2。

The fuel cell is considered to be one of the potential clean energy. In this study, the platinum catalyst was made and applied to the proton exchange membrane fuel cell, to investigate the effects of different operating conditions and manifold design its efficacy. The preparation of platinum catalyst is based on the carbon nanotube as a carrier, using the dry impregnation method to impregnate it in the solution of dihydrogen hexachloroplatinate (IV) hexahydrate, then reduced by sodium borohydride. The catalyst prepared was characterized with XRD, SEM, TEM and other instruments. The catalyst slurry was formulated on the 50% hydrophobic of carbon paper. After thermoforming it with the Nafion® 117, the so-called membrane electrode assembly was under a series of single cell test. By changing the operating parameters (cell operating temperature, flow rate, cathode oxygen feed concentration, locking torque, etc.) and manifold design (open ratio, flow patterns, etc.), the results of the fuel cell polarization curves (VI curve) and power curve (PI curve) can be the basis of battery performance. Experimental results show that supplying high oxygen concentration to the cathodes, increasing the flow rate of hydrogen to the anode and air to the cathode, can improve the performance of a single cell. Different channel areas affect the open ratio: it too high will reduce its effect of electronic collection, while it too low will not make full use of the catalyst, and the optimum value is 63% in the experimental. Finally, the serpentine channel is not easy to accumulate water in the cathode, having a small diffusion resistance, allowing a superior performance of it over that of the parallel channel. This study use air as oxidant to achieve the best performance 176.3 mW/cm2.
