摘要：
To improve the output power of marine sediment microbial fuel cells, in this study, the electricity generation performance of an amine-modified anode was examined. A new type of nitrogen-doped modified anode was prepared by introducing nitrogen-doped functional groups on the anode surface and heat treatment at 600 ℃. Compared with a blank group, the number of bacteria attached to the melamine modified anode surface increased by 4.6 times, the cyclic voltammetric capacity increased by 3.8 times, and the relative kinetic activity increased by 7.7 times. The maximum output power density of the modified anode battery is 67 mW/m2, which is 2.4 times that of the blank group, and its long-term output voltage keeps a steady state at approximately 790 mV. The preparation method of the modified anode is simple and low in cost. This study provides a new idea for the design and development of the anodes of submarine microbial fuel cells. © 2022 Editorial Board of Journal of Harbin Engineering. All rights reserved.
