▎ 摘　　要

NOVELTY - The method involves obtaining a uniform and stable dispersion of graphene oxide water solution. The graphene aqueous solution is mixed with the substrate electrode, and is dryed naturally to obtain graphite oxide/substrate electrode. The graphene/base electrode is obtained by natural drying. USE - Method for preparing graphene electrode and polyaniline - graphene electrode used in microorganism fuel cell (all claimed). ADVANTAGE - The process is simple and convenient to use. The power output of the microbiological fuel cell can be improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene electrode and polyaniline - graphene electrode.
