直接微生物燃料电池酒精酵母产电及驯化
DOI: 10.3724/SP.J.1145.2010.00412, PP. 412-414
Keywords: 酒精酵母,直接微生物燃料电池,产电,驯化
Abstract:
为提高微生物燃料电池（microbialfuelcell,mfc）的输出功率，降低成本，使实际应用成为可能，首次以酒精酵母为产电微生物，在不添加电子传递中间体的条件下，采用开路电压法和极化曲线法对自行设计的电池装置进行性能优化及产电效果研究，同时选取菌种驯化法对酒精酵母的产电适应性进行探讨.结果显示，铁阳极的电化学活性远高于铝阳极和铜阳极，且阳极形状对产电能力有影响；此mfc最大开路电压和输出功率密度分别为1.252v和502.3mw/m2，内阻为777.43ω；菌种经驯化电流峰值提前，产电适应性增强.实验结果表明，本研究设计的系统性能良好，调整阳极材料和形状可提高电池产电能力，可通过驯化对菌种进行产电稳定性研究.图4参20
