Abstract

The invention proposes a method for increasing the output power of microbial fuel cells by adopting the droplet-based microfluidics technology. The method includes the following steps: (1) setting up a droplet-based microfluidics experimental device platform; (2) setting up an experimental solution picoinjection device; (3) setting up a bacteria database; (4) setting up a matrix material database; (5) making a microbial fuel cell device with a shaking anode; (6) measuring the output power of the cell device by adopting the matrix material in the matrix material database in the step (4), the droplet bacteria in the bacteria database in the step (3) and the microbial fuel cell device in the step (5) under the specific matrix material and specific bacteria conditions, and screening out the bacteria and the optimal matrix material that can make the microbial fuel cells to achieve the maximum power. The droplet-based microfluidics experimental method provided by the invention has the advantages that the cost is low and batch experiments are available.

Description

technical field [0001] The invention relates to the technical field of sustainable development and regeneration of new energy, and in particular to an experimental method capable of improving a droplet microfluidic technology that currently limits the large-scale popularization and application of microbial fuel cells. Background technique [0002] Recent Nobel laureate Richard Smalley has often said that "the energy problem is the greatest challenge facing mankind". Scientists have tried to find alternatives to petroleum, such as methane hydrate and converting coal into biogas, but these alternatives have a side effect, they will release carbon dioxide, thereby exacerbating the global warming effect, although nuclear energy can provide carbon-free clean energy, but there is currently no effective and safe way to deal with nuclear waste. Therefore, a series of sustainable alternative energy sources should meet the requirements of zero carbon emissions and renewable energy, s...
