We created a new graphite-Cu(Ⅱ) electrode and found that the electrode could catalyze FADH₂ oxidation and FAD reduction coupled to electricity production and consumption, respectively. In a fuel cell with graphite-Cu(Ⅱ) anode and graphite-Fe(Ⅲ) cathode, the electricity was produced by coupling to the spontaneous oxidation of FADH₂. Fumarate and xylose were not produced from the enzymatic oxidation of succinate and xylitol without FAD, respectively, but produced with FAD.
