BIOCELL

摘要

A material participating in the donation and receiving of electrons; a biofuel cell making use of the material that exhibits an enhanced output power density; and a process for producing them. In particular, there is provided a material comprising an electron conductor of = 0.5 m<SUP>2</SUP>/g external specific surface area being a specific surface area relating to pores of = 7 nm, a redox polymer and a biocatalyst or analogue thereof, wherein the redox polymer has an oxidation-reduction moiety exhibiting oxidation-reduction behavior and exhibits an electron conductivity of = 10<SUP>-16</SUP> S/cm.
