海底微生物燃料电池具有底物丰富、可长期运行、维护成本低和环境友好等特点，具有很好的研究价值和广阔的发展前景。但由于其低的功率密度输出和长期运行的不稳定性，使海底微生物燃料电池尚未得到广泛地实际应用。选取海底沉积泥用于实验室构建的海底微生物燃料电池装置中，比较了在不同阳极材料、阴阳极面积比、阳极修饰、阳极泥下深度条件下海底微生物燃料电池的功率密度输出及其电化学性能，得出最佳的海底微生物燃料电池阳极材料为碳毡；阴极及电极最佳面积比为1∶1；最佳阳极修饰为氨水浸渍；最佳阳极泥下深度为2 cm。

Benthonic microbial fuel cells, with advantages of abundant sources in substrates, long-term operation, low maintenance cost and environmentally friendliness, etc, have high research value and broad prospects for development.At present, there are only limited usages for benthonic microbial fuel cells in practical application, mainly for its low power density output and long-term running instability.Therefore, this study took submarine sedimentary mud as the substrate for benthonic microbial fuel cells construction, and the cells were tested by different anode material, cathode-anode electrode area ratios, different anode modifications methods and anode depth underneath submarine sedimentary.Results showed that carbon felt was so far the best benthonic microbial fuel cell anode material, while the best cathode-anode electrode area ratio was 1∶1, the best anode modification method was ammonia treatment, and the best anode depth underneath submarine was 2 cm.
