| 本文采用静电纺丝和烧结工艺相结合的方式，制备了以碳纤维为载体的纳米PtSn 阳极催化剂并组装单电池。采用X射线粉末衍射（XRD）、红外光谱（FTIR）、扫描电镜（SEM）等分析测试手段对纳米催化剂进行表征，并对电池进行电化学性能测试。研究表明，从DEFC单电池性能角度考虑，当乙醇溶液浓度1.0 mol/L，溶液进样速率1.0mL/min，溶液温度为80℃，氧气进样流速为100ml/min时结果较优，单电池的最高功率密度达18.2mW/cm2。 |

| This ariticle combined the electrospinning and sintering technology to prepare nano PtSn as anode catalyst which is loaded by carbon fiber and also to assemble single battery. It used the X-ray powder diffraction (XRD), infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and some other testing technology to charaterize the nano catalyst and also test the battery’s electrochemical property. Based on the performance of DEFC single battery, this anode proves better when the concertration of ethanol is 1.0 mol/L , the sample rate of solution is 1.0 mL/min, the tempreture is 80℃,and injection rate of oxygen is 100 mL/min. Meantime, the highest Power density of the single battery is 18.2 mW/cm2. |
