Non-amboceptor microbial fuel cell

Said non - mediator microbiological fuel cell, without adding mediator, includes anode chamber having microgerm bacterium liquid and organism fuel and anode and cathode set in chamber; wherein said cathode being air contacted hollow bar type composite cathode or plate type composite cathode; microgerm bacterium liquid being Gs, Gm or Rf zymotic fluid taken from Deutsche Sammlung von Mikroorganismen und Zellkulturen (DSMZ); organism fuel being glucose, levulose, sucrose, sacchariferous byproduct from timber head or straw, and industrial and agricultural organic waste and/or city life refuse. The electron of said battery is direct transferring, which can raise battery power density, both increasing an energy source and reducing contamination.
