Experimental Study of Bioelectrochemical Fuel Cell Using Bacteria from Baltic Sea

摘要

A bioelectrochemical fuel cell using bacteria as catalyst was investigated inthis paper. The bacteria were obtained from the bottom sediment of Baltic Sea, and then cultivated in a 1 liter bioreactor. Raw material for fermentation were glucose first and then fish meat or plankton biomass. After certain fermentation time, broth was used as fuel for the fuel cell. A steady power output (200 microW/ml anodic volume) was obtained by using stainless steel net packing with graphite particles as the anode electrode. Different fermentation conditions were tested for maximum electroactive substance output. The experimental study of the fuel cell were carried out in the following manners: (1) characteristics of the fuel cell; (2) mediator effect on the current output; (3) mode of the fuel flow.
