The potential of using sodium bromate as a cathodic electron acceptor in a microbial fuel cell (MFC) was determined in this study. The effects of sodium bromate concentration and initial catholyte pH on the electricity production of the MFC were investigated. The MFC performance improved with increasing sodium bromate concentration and decreasing catholyte pH. The maximum voltage output (0.538 V), power density (1.4908 W m(-3)), optimal open circuit potential (1.635 V), coulombic efficiency (11.1%), exchange current density (0.538 A m(-3)) and charge transfer resistance (4274.1 Ω) were obtained at pH 3.0 and 100 mM sodium bromate. This work is the first to confirm that sodium bromate could be used as an electron acceptor in MFCs.
本研究旨在确定溴酸钠作为微生物燃料电池（MFC）阴极电子受体的潜力。考察了溴酸钠浓度和初始阴极电解液 pH 值对 MFC 发电性能的影响。随着溴酸钠浓度的增加和阴极电解液 pH 值的降低，MFC 的性能得到了改善。在 pH 值为 3.0 和 100mM 溴酸钠时，获得了最大电压输出（0.538V）、功率密度（1.4908Wm(-3)）、最佳开路电位（1.635V）、库仑效率（11.1%）、交换电流密度（0.538Am(-3)）和电荷转移电阻（4274.1Ω）。这项工作首次证实溴酸钠可以作为 MFC 中的电子受体。
