| 摘 要： | 使用铁代替铂作为阴极催化剂,制作含铁碳布空气阴极并构建单室MFC(Fe-C-ACMFC)。以乙酸钠为燃料,通过稳态放电法和循环伏安测试等测试手段,分析了不同铁含量对Fe-C-ACMFC产电性能的影响以及性能最优Fe-C-ACM-FC的连续运行稳定性。结果表明,随着铁含量的增加,Fe-C-ACMFC启动期开路电压(OCV)逐步提高,达到峰值后,随着铁含量的增加而降低;同样,Fe-C-ACMFC极化性能和功率密度等产电性能也随铁含量的增加先升高再降低;当铁含量为0.7 mg/cm2时,MFC的产电性能最优,最大开路电压为593 mV,表观内阻为89Ω,最大功率密度达到12 907 mW/m3,并且经循环伏安测试,电池放电容量几乎没有变化,表明Fe-C-ACMFC的性能比较稳定,能够长期运行。由于铁催化剂价格远远低于铂催化剂,因此,铁碳布空气阴极MFC更利于推广应用。
