Microbial fuel cells exploit the metabolism of bacteria in order to generate electricity. A new type of biofilm developed in Bayreuth could soon make this relatively young technology considerably more effective, more stable, and easier to use. A research team at the University of Bayreuth has succeeded in producing a material that is far better suited for energy production in fuel cells than natural biofilms. The scientists described the advantages of their new findings in the journal Macromolecular Bioscience.
