中文摘要 提出兩種以奈米銀的非鉑觸媒作為陰極觸媒電極應用於鹼性陰離子交換膜燃料電池。針對該碳黑奈米銀觸媒之表面與元素組成分析, X光繞射顯示奈米銀粒子成功附著於碳黑, 同時以電子顯微鏡與穿隧顯微鏡分析此奈米銀粒徑小於20奈米。研究成果呈現出, 此奈米銀碳載體應用於陰極上, 與鉑碳載體的電性功率表現, 已可作取代效應(相差僅有3.5%),以成功實現非鉑觸媒於陰極應用於鹼性陰離子交換膜燃料電池。
英文摘要 Two kinds of non-platinum metal catalysts, 40 wt% Ag/C (Ag/C) prepared using the impregnation method and commercial nano-silver powder (commercial Ag) were used as the cathode catalysts in alkaline anion exchange membrane fuel cells (AEMFC). In the surface measurement and elemental composition analysis of the prepared Ag/C catalyst, XRD revealed that the silver nanoparticles were successfully produced and attached onto the carbon black supporter. In addition, SEM and TEM analyses showed the silver nanoparticle size catalyst was less than 20 nm in the synthesized Ag/C. EDX and TGA analyses confirmed that the actual Ag loading in the Ag/C catalyst was near the calculated value in the synthesis procedure. For AEMFC performance tests, the results showed that the maximum power densities using Ag/C, commercial Ag, and Pt/C as the cathode catalysts were 200 mW cm−2 at 0.4 V, 105 mW cm−2 at 0.3 V, and 207 mW cm−2 at 0.5 V which were consistent with the CVs and LSV characterizations. These results indicated that the performance of tested AEMFC with Ag/C and commercial Ag catalysts was 3.5% and 49.3% less than that of AEMFC with Pt/C, respectively. This study successfully implemented non-Pt catalyst for the cathode electrode in AEMFC applications.
