摘要

摘要: 采用自制的碳纤维基PtSn催化剂薄膜作为阳极催化剂,商用Pt/C作为阴极催化剂,Nafion 115膜作为质子交换膜,通过热压制成膜电极,组装平板型直接乙醇燃料单电池,搭建测试系统并进行性能的测试,研究了温度、乙醇浓度、溶液流量、进气流量等参数对DEFC的影响。结果表明,当乙醇溶液浓度为1.0 mol/L、溶液进样流量为1.0 mL/min、溶液温度为80 ℃、氧气进样流量为100 mL/min时结果较优,单电池的最高功率密度达18.2 mW/cm²。

Abstract: PtSn anode catalyst supported on carbon fiber was taken as the anode catalyst of the MEA. Commercial Pt/C catalyst was used in MEA as the cathode catalyst. The Nafion 115 membrane was the proton exchange membrane of the MEA. MEA was fabricated by hot-pressing. The sing flat cell was assembled with the prepared MEA. The influences of temperature, ethanol concentration, rates of liquor and O₂ were studied. The results showed that the performance of the fuel was better when the concentration of ethanol was 1.0 mol/L, the rate of liquor was 1.0 mL/min, the temperature was 80 ℃, and the rate of O₂ was 100 mL/min, the maximum power density of the fuel reached about 18.2 mW/cm².
