A Generation of Microbial Fuel Cells with Current Outputs Boosted by More Than One Order of Magnitude

Abstract

Ever-ready microbes: A microbial fuel cell (depicted) that continuously generates a current output more than one order of magnitude greater than known microbial fuel cells (up to 1.5 mA cm−2) is reported. The novel fuel cell concept uses polymer-modified catalytically active anodes that shuttle electrons from the bacterial suspension to the anode.
