IMPROVED BIOFUEL CELL

摘要

The present invention discloses a new type of biofuel cell, based on the microbial regeneration of the oxidant, ferric ions. The biofuel cell is based on the cathodic reduction of ferric to ferrous ions, coupled with the microbial regeneration of ferric ions by the oxidation of ferrous ions, with fuel (such as hydrogen) oxidation on the anode. The microbial regeneration of ferric ions is achieved by metal oxidizing chemolithotrophic microorganisms from the Leptospirillum genus (excluding Leptospirillum
