Microbial fuel cell and the in-situ analyzing method of microorganism using it

摘要

The present invention relates to a microbial fuel cell, and more particularly to a microbial fuel cell having a reduction reaction vessel 100 and a reduction electrode unit including a reduction electrode horizontally disposed at a lower end of the reduction reaction vessel 100; The reduction reaction vessel 100 includes a first electrolyte; An oxidation electrode unit located above the reduction electrode unit and including an oxidation reaction vessel and an oxidation electrode placed horizontally inside the oxidation reaction vessel; A second electrolyte filled in the oxidation reaction vessel; A separation membrane for separating the reduction electrode unit and the oxidation electrode unit; And an external circuit connected to the oxidation electrode and the reduction electrode, wherein the oxidation reaction vessel is open at an upper portion thereof, and the oxidation electrode is designed to be visible from the outside of the battery . The microbial fuel cell has an advantage that it can observe the interaction between the microorganism and the electrode, which has been difficult to observe in the prior art, in real time by opening the oxidizing electrode portion and exposing the oxidizing electrode. In addition, the microbial fuel cell has a small stacked structure, which is easy to manufacture, has an advantage of observing microbial behavior and electrical characteristics in real time by controlling an external voltage or resistance.
