Definition of FUEL CELL. : a device that continuously changes the chemical energy of a fuel (as hydrogen) and an oxidant directly into electrical energy.
From Wikipedia, the free encyclopedia. A microbial fuel cell (MFC) or biological fuel cell is a bio-electrochemical system that drives a current by using bacteria and mimicking bacterial interactions found in nature.MFCs can be grouped into two general categories, those that use a mediator and those that are mediator-less. microbial fuel cell is a device that converts chemical energy to electrical energy by the catalytic reaction of microorganisms. A typical microbial fuel cell consists of anode and cathode compartments separated by a cation (positively charged ion) specific membrane.
