▎ 摘　　要

NOVELTY - The electrode has a composite electrode comprising an electric conduction substrate, graphene and manganese dioxide. The electric conduction substrate is made of a stainless steel felt or a carbon felt and cathode liquid is made of potassium ferricyanide solution. The graphene is fixed with a surface of the electric conduction substrate. USE - Composite electrode for micro-organism fuel battery (claimed). ADVANTAGE - The electrode increases electric transmission efficiency of positive pole, electric property of producing micro-organism fuel battery and biological weight that is attached to an anode. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a composite electrode method (2) a micro-organism fuel battery. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a composite electrode. '(Drawing includes non-English language text)'
