| 本文采用靜電紡絲和燒結(jié)工藝相結(jié)合的方式，制備了以碳纖維為載體的納米PtSn 陽極催化劑并組裝單電池。采用X射線粉末衍射（XRD）、紅外光譜（FTIR）、掃描電鏡（SEM）等分析測試手段對納米催化劑進(jìn)行表征，并對電池進(jìn)行電化學(xué)性能測試。研究表明，從DEFC單電池性能角度考慮，當(dāng)乙醇溶液濃度1.0 mol/L，溶液進(jìn)樣速率1.0mL/min，溶液溫度為80℃，氧氣進(jìn)樣流速為100ml/min時(shí)結(jié)果較優(yōu)，單電池的最高功率密度達(dá)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. |
