▎ 摘  要

NOVELTY - The anode has a water soluble inner layer encapsulating a conductive material and a microorganism. An outer layer is provided with a rigid porous membrane. The outer layer encapsulates the inner layer. A metal conductor is positioned across the outer layer, the inner layer, and in contact with the conductive material. The rigid porous membrane is water insoluble. The inner layer comprises a water soluble polymer selected from the group consisting of gelatin, dextran, collagen, alginate, chitosan, agarose, poly ethers, poly vinyl alcohol, carrageenan, agar and combination. The conductive material comprises a conducting redox polymer, carbon nanotube (CNT), graphene, activated carbon, carbon paper, carbon cloth, carbon felt, carbon wool, carbon foam, graphite, porous graphite, graphite powder, graphite granules, graphite fiber, electron conductive polymers, metal, process stimulators and accelerators, or combination. USE - Anode used in microbial electrolysis cell (MEC) of microbial electrochemical system, for use in wastewater (WW) treatment, waste treatment, electricity generation, energy generation and hydrogen production (all claimed), used as energy source for remote sensors and motors. ADVANTAGE - The anode has high surface area for electrogenic biofilm formation, functional groups that will support the sustainable attachment of the bacteria to the surface, and high conductivity to support effective electron transfer from the microorganism to the conductive surface of the anode material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for using microbial electrochemical system. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the anode prototype.
