中文摘要 本研究主要探討使用非貴金屬催化劑作為陰極電極,以提升陰離子交換膜燃料電池(AEMFC)性能。因為銀奈米粒子具有優異的氧還原反應(ORR)特性且相較於鉑(Pt)成本更低,因此它們是AEMFC陰極電極的良好候選材料。有兩種方法可以實現以Ag取代Pt的目標。第一種是使用銀奈米粒子製程,其所得電池性能與Pt相近,差距為3.5%。另一種是使用硝酸鋯修飾Ag表面以提升電池性能。在實驗中,使用酸洗的Vulcan XC72R炭黑以增加其表面的官能基,這也可以增加銀奈米粒子與陰極基材的結合。硝酸銀經由化學過程被還原為銀奈米粒子以用於陰極。結合還原劑硝酸銨鋯與管式爐退火過程中的氮氣環境,完成了含40 wt %銀奈米粒子的陰極催化劑。鉑(Pt/C)(40 wt %)與異丙醇(IPA)和去離子水(DI)按一定比例混合後用於陽極。實驗發現,陽極Pt/C與IPA、DI的混合比例為7:3,陰極Ag/C與IPA、DI的混合比例為5:5。透過此研究,發現最高的電池性能達到623 mW/cm²。本研究可實現將非貴金屬催化劑銀奈米粒子用作AEMFC的陰極。
英文摘要 This research mainly explores the non-precious metal catalyst used as in the cathode electrode to improve the anion exchange membrane fuel cell (AEMFC) performance. Because nano-silver particles with excellent oxygen reduction reaction (ORR) characteristics and lower cost compared to Pt, they are good candidates for cathode electrode in AEMFC. Two approaches can realize the target to use Ag instead of Pt. It was implemented with processing Ag nano-particle, the resulted cell performance close to Pt with 3.5 % difference. The other one is to modify Ag surface using cerium nitrate to enhance cell performance. In the experiment, the pickling Vulcan XC72R carbon black was used to increase functional group of Vulcan XC72R carbon black attached on their surface. It also can increase Ag nano-particles to integrate with the cathode substrate. The silver nitrate was reduced to Ag nano-particles through a chemical process for the cathode. Combined with the reducing agent ammonium cerium nitrate and the N2 gas environment during the annealing of the furnace tube, the cathode catalyst with 40 wt % Ag nano-particles were completed. While platinum (Pt/C) (40 wt %) was mixed with isopropanol (IPA) and deionized water (DI) with a certain ratio for the anode. It was found to be 7:3 (IPA, DI) mixed with Pt/C for the anode and then 5:5 (IPA: DI) mixed Ag/C for the cathode. Through this study, it was found that the highest cell performance reached 623 mW/cm2. It can implement non-precious metal catalyst, Ag nano-particles, to be used as cathode for AEMFC.
