由於能源危機，發展替代能源就成為重要議題。燃料電池是綠色能源的一種，使用氫氣和氧氣當燃料，在反應過程中只會產生水，因此不會造成環境污染。然而，燃料電池使用白金觸媒，造成燃料電池價格偏高。因此，本研究在發展低價格和高效能的非貴重金屬材料以應用於燃料電池。
　　本研究分成二個部份。第一部份以導電高分子聚吡咯與維生素B12混合附載於多孔活性碳XC-72R上，經由不同溫度熱燒結後，所得到的觸媒應用在質子交換膜燃料電池的陰極端以做氧氣還原反應。這些觸媒在過氯酸水溶液中測試，當觸媒燒結溫度在700oC時，觸媒具有最好的氧氣還原反應能力，其電子轉移數可達3.98。質子交換膜燃料電池使用此觸媒在陰極端，其輸出最大功率可達300 mW/cm2。
　　第二部份為混合石墨烯氧化物與維生素B12，經由各種溫度之
燒結得到各種觸媒。經由XPS分析，發現燒結溫度900oC時，quaternary-N以及pyridine-N鍵結形式總含量較其他燒結溫度處理觸媒多，此觸媒在氧氣飽和氫氧化鉀水溶液中，其電子轉移數可達3.90。鹼性陰離子交換膜燃料電池使用此觸媒，輸出最大功率可達65 mW/cm2 。

　Recently due to energy crisis the development of alternative energy becomes an important issue. Fuel cell is an eco-friendly energy source. It uses hydrogen and oxygen as fuel and oxidant, respectivity, which the by product is water without pollutants. However, the fuel cell uses high cost of platinum as catalyst, making it high cost.Therefore, the goal of this study is to investigate the development of high-performance but low-cost non-precious metals catalysts.
　　The first part is to use the mixture of polypyrrole and vitamin B12 that are supported on carbon black (XC-72). After the mixture was pyroylzed by various temperatures, the pyrolyzed catalysts wae then applied in the cathode of a proton exchange membrane fuel cell (PEMFC) for oxygen reduction reaction (ORR). These catalysts show the highest
ORR activity at the pyrolysis temperature of 700oC in 0.1M HClO4
and the electron-transfer number is 3.98. The PEMFC using the catalyst
pyrolyzed at 700oC in the cathode side shows a maximum power density of 300 mW cm-2.
　　The second part is to use the mixture of graphene oxide and vitamin B12,which was pyrolyzed by various temperatures.According to the XPS
analysis, the catalyse pyrolyzed at 900oC shows the most content of
quaternary-N and pyridine-N bonding structure. The ORR activity is carried out in O2-saturated 0.1M KOH, the electron transfer number
approached 3.90. The catalyst is applied in the cathode side of the anion alkaline exchange membrane fuel cell (AAEMFC) ,which shows the
maximum power density of 65 mW cm-2.
