中文摘要：
构造并成功启动了带有蛇形流场的微生物燃料电池（SMFC）,测试了SMFC性能,探讨了高电流下电池性能下降的原因,研究了底物流速、浓度和流场结构形式对电池性能的影响.实验结果表明：SM FC在大电流时发生电压急剧下降现象,这主要是由于阳极物质传输受限所致;SMFC最大功率密度随着阳极底物流速和浓度的增加而增加;交指流场结构有助于底物传输,因此在相同的底物流速和浓度下,具有交指流场阳极的微生物燃料电池（IMFC）最大功率密度得以提高.
英文摘要：
A microbial fuel cell with serpentine flow field （SMFC） was constructed and investigated experimentally. The performance of the SMFC was tested and the influences of substrate flow rate, concentration and pattern of flow field on the SMFC performance were investigated. The experimental results show that the cell voltage drops sharply under high current density and the reason is attributed to mass transfer limitation in anode. The maximum power density of the SFMC increases with increasing flow rate and concentration of the influent substrate. The performance of MFC using an interdigitated flow field in anode is higher than that of SMFC under the same operational conditions due to better mass transfer process induced by the interdigitated flow field.
