Floating-type microbial fuel cell
First Claim
1. A floating-type microbial fuel cell comprising:
- a reactor having a lower substrate inlet/outlet port disposed in a lower surface thereof and a side substrate inlet/outlet port disposed in a lower side portion thereof, and an upper connection hole formed in an upper surface thereof;
a cathode installed on the upper surface of the reactor;
an anode electrically connected to the cathode, and installed in a lower region of the reactor;
an ion exchange membrane installed between the anode and the cathode;
a vent hole foci ted for discharging gases generated under the anode by microorganisms to the exterior and not accumulating the gases under the ion-exchange membrane; and
a floating unit installed at an outer periphery of the reactor and floatable in a substrate solution,wherein the cathode is positioned at a region in the substrate solution having a dissolved oxygen concentration higher than that of a region at which the anode is positioned, and the anode is positioned at a region in the substrate solution having an amount of electrons generated by microorganisms larger than that of a region at which the cathode is positioned.

Abstract
Provided is a floating-type microbial fuel cell capable of effectively generating energy from organic contaminants of contaminated waters. The floating-type microbial fuel cell includes a cathode, an anode electrically connected to the cathode, and a floating unit connected to the cathode and/or the anode and floatable in a substrate solution, wherein the cathode is positioned at a region in the substrate solution having a dissolved oxygen concentration higher than that of a region at which the anode is positioned, and the anode is positioned at a region in the substrate solution having an amount of electrons generated by microorganisms larger than that of a region at which the cathode is positioned.
