Abstract

The invention relates to a microbial fuel cell output energy management system taking urine as fuel, the system comprises a microbiological fuel cell stack, a first capacitor bank, a second capacitor bank and a state switching module; the state switching module is used for alternately controlling the first capacitor bank to be in a charging state and the second capacitor bank to be in a discharging state according to preset switching time, or controlling the first capacitor bank to be in the discharging state and the second capacitor bank to be in the charging state. In an initial state, the microbial fuel cell stack charges the first capacitor bank, the second capacitor bank discharges an external load, a preset switching time is waited, and the state switching module controls the microbial fuel cell stack to charge the second capacitor bank and controls the first capacitor bank to discharge the external load. The whole system adopts an alternate operation mode to realize that two groups are respectively in charging and discharging states at the same time, voltage reversal is effectively eliminated, and stable power output is realized.

Description

technical field [0001] The present application relates to the technical field of bioelectrochemistry, in particular to a microbial fuel cell output energy management system using urine as fuel. Background technique [0002] A microbial fuel cell is a device that uses microorganisms to directly convert chemical energy in organic matter into electrical energy. Microbial fuel cells offer new opportunities to sustain energy production from biodegradable, reduced compounds, for example using urine as one of the main raw materials. [0003] On the other hand, related studies have shown that urine accounts for 1% of urban sewage volume and contributes more than 80% of the total nitrogen in urban sewage influent. The separation and effective treatment and utilization of urine sources not only reduce the treatment burden of urban sewage plants, but also Can save water resources. Microbial Fuel Cell (MFC) can simultaneously realize the removal of pollutants and energy recovery proce...
