Abstract:	在本研究中，將利用固相反應法(Solid State Reaction, SSR)所製備的傳統和合金陽極用於質子傳導型固態氧化物燃料電池(Proton Conducting Solid Oxide Fuel Cell, P-SOFC)。本研究的目的是與傳統的Ni陽極相比，為P-SOFC開發更好的抗碳性陽極。將Cu摻雜到Ni-BCZY陽極中可以提高P-SOFC中陽極的抗碳沉積能力。合金(Ni：Cu)之比和煆燒參數(例如時間和溫度)的幾種變化將會影響催化劑的抗碳沉積能力和電導率。首先我們研究了合適煆燒的操作時間和溫度，然後改變了Ni：Cu的比例。研究結果顯示，煅燒時間和煅燒溫度的變化可以改變粒徑、電導率和熱膨脹係數(Coefficient of Thermal Expansion, CTE)。當莫爾比為95：5(Ni：Cu)時，NiCu陽極在800°C下煅燒0.5小時，在600°C的工作溫度下具有2140 S / cm的電導率，其CTE為16.07×10-6 K-1 。儘管NiCu的電導率低於傳統的Ni陽極(2241 S / cm)，但它顯示出優異的抗碳沉積性能，此外，對於Ni：Cu莫爾比為7：3觀察到最佳的抗碳沉積性能。;In this research, solid-state reaction (SSR) synthesis process is used to prepare alloy catalyst as an anode in proton conducting solid oxide fuel cell (P-SOFC). The aim of this research is to develop a better carbon resistance anode for P-SOFC, when compared to conventional Ni anode. Doping copper into Ni-BCZY anode can enhanced the carbon resistance of anode in P-SOFC. Several variations in the ratio of alloy (Ni : Cu) and calcining parameters such as time and temperature would affect the carbon deposition resistance and electrical conductivity of the catalyst. Initially, we investigated the best appropriate calcination duration and temperature, and then the ratio of Ni : Cu is varied. The results show that the variation of calcined time and calcined temperature can change the particle size, electrical conductivity and coefficient of thermal expansion (CTE). NiCu anode with molar ratio of 95 : 5 (Ni : Cu) calcined at 800 °C for 0.5h exhibit an electrical conductivity of 2140 S/cm at operating temperature of 600 °C with a CTE of 16.07 × 10-6 K-1. Although the NiCu have a lower electrical conductivity than the traditional Ni anode (2241 S/cm), it shows a good performance of carbon deposition resistance, the best carbon deposition resistance observed for the Ni : Cu molar ratio of 7 : 3. This work can help to replace the conventional Ni anode in P-SOFC.
