本文设计了基于无Pt电极的自呼吸式阴离子交换膜(AEM)直接葡萄糖燃料电池(DGFC),并对其性能进行了实验研究.结果表明,在室温下,自呼吸式AEM-DGFC的最大功率密度达到20.8 mW·cm-2,最大电流密度为156mA·cm-2,优于以葡萄糖为反应物的传统的微生物燃料电池和酸性直接葡萄糖燃料电池(PEM-DGFC).实验还探究了葡萄糖浓度以及KOH浓度对于自呼吸式直接葡萄糖燃料电池性能的影响,葡萄糖浓度的升高一方面会降低传质极化,另一方面会阻碍OH-的传输,增大电池的内阻.0.7 M浓度的葡萄糖使燃料电池性能达到最优最优.KOH浓度从2M升高到4M时,使得阳极的GOR速率加快,电池性能进一步提升.
