THREE ELECTRODE TYPE OF MICROBIAL FUEL CELL AND A METHOD FOR OPERATING THE SAME
First Claim
1. A three electrode type microbial fuel cell comprising:
- a sediment electrode acting as an anode and placed in sediment on the bottom of a contaminated water zone;
an intermediate electrode acting as an anode or a cathode and placed in water; and
an floating electrode acting as a cathode and placed adjacent to a water surface.

Abstract
Provided are a three electrode type microbial fuel cell and a method of operating the same. The fuel cell includes a sediment electrode acting as an anode and placed in sediment on the bottom of a contaminated water zone, an intermediate electrode acting as an anode or a cathode and placed in water, and an floating electrode acting as a cathode and placed adjacent to a water surface. In the three electrode type microbial fuel cell, the intermediate electrode may be used as an anode or a cathode according to the concentration of organic contaminants in water of the contaminated water zone, so that the fuel cell can continue to generate electricity in any case where the organic contaminants are present in or removed from the water.
