The invention belongs to the technical field of microbial power generation, and discloses a device and method based on microbial power generation and application of the device and method. According to the method, algae is cultured and fermented to obtain fermentation liquor, the fermentation liquor is decomposed and metabolized into small molecular organic matters and gas through heterotrophic bacteria, methanogens ferment the small molecular organic matters and the gas in an oxygen-free environment to obtain methane gas, and the methane gas enters a methane fuel cell to generate electric energy. Methane oxidizing bacteria in the methane fuel cell oxidize methane to generate formic acid, the formic acid is further utilized by shewanella to generate CO2 and simultaneously obtain electrons, and the electrons are conducted to an anode by an extracellular electron transfer mechanism of the shewanella so as to generate electric energy. The power of the fuel cell provided by the invention is 89.5 W, so that the operation of the ship body and equipment on the ship body can be met, and the electric energy requirement of the ship body for sailing in a pollution-free sea area can also be ensured.

    本发明属于微生物发电技术领域,公开了一种基于微生物发电的装置、方法及其应用。本发明将藻类培养发酵得到发酵液,发酵液通过异养菌分解代谢为小分子有机物和气体,产甲烷菌利用小分子有机物和气体在无氧环境中发酵得到甲烷气体,甲烷气体进入甲烷燃料电池中产生电能。甲烷燃料电池中的甲烷氧化菌将甲烷氧化产生甲酸,甲酸被希瓦氏菌进一步利用生成CO2同时得到电子,由希瓦氏菌胞外电子传递机制将电子传导至阳极从而产生电能。本发明提供的燃料电池功率为89.5W,能够满足船体和其上设备的运行,也能够保证船体在无污染海域航行的电能需求。
