US 2021/0280888 A1 · MICROBIAL FUEL CELL

Abstract

A microbial fuel cell (1) includes: a negative electrode (10) composed of a carbon material (11) formed by laminating a plurality of graphenes (12) on one another, in which an area of exposed surfaces of the carbon material, the exposed surfaces going along a lamination direction (X) of the graphenes, with respect to a volume of the carbon material is 1.0×10−5 to 20 cm2/cm3; and a positive electrode (20) facing the negative electrode. Then, the negative electrode and the positive electrode are immersed in an electrolysis solution (70), and at least a part of the positive electrode is exposed to a gas phase (2).
