<P>PROBLEM TO BE SOLVED: To provide a high-power bio fuel cell capable of improving electrode performance without reduction of electrode surface area, physical stability, and liquid permeability. <P>SOLUTION: A bio fuel cell 10 comprises: an anode (negative electrode) 1 that is a fuel electrode, an anode current collector 4, a separator 3, a cathode current collector 5, a cathode (positive electrode) 2 that is an air electrode, and a gas-liquid separation membrane 6, which are arranged, in the order, between a fuel tank 7 and a positive electrode cover 8. In the bio fuel cell 10, an electrode which is made of a carbon fiber cloth forming a network structure with a single fiber bundle of carbon fibers and of which an oxidoreductase exists on the surface is used at least for the anode 1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
