With the soar demand for electricity, unstable rising oil prices and increasingly serious environmental problems, the development of renewable energy has become a social consensus. Glucose fuel cell is a kind of energy storage device.which has the advantages of economic environment protection and long-term stabl power supply. However, the disadvantages of low glucose oxidation efficiency, high cost, poor stability, and toxicity of electron mediators largely hamper the practical application of fuel cell.

we use glucose to reduce graphene oxide, and then the graphene is immobilized on the nickel foam surface by doping method, which does not use electron mediators and has high cataly ticrate of glucose oxidation, When the mass ratio of graphene to activated carbon is 0.075:l, the maximum power density of glucose fuel cell is 13.08 W m, which is 35.26% higher than that of the blank anode cell. The results of EIS and LSV show that the uniformly distributed graphene in the activated carbon layer plays an important role in improving the electro chemic catalytic activity.

Then we demonstrate a one-step method to produce nickel foam electro demodified with graphene and nickel oxides. The structure and morphology of there sulting 3D graphene foam and nickel foam are characterized by Raman,XPSand SEM. The maximum power density of glucose fuel cell equipped with this electrode as anode is up to 13.48 W m-², which is higher than that of the doped graphene modified anode cell. LSV result shows that the polarization degree of this anode is significantly lower than that of doped graphene modified anode, which indicated that the synergistic effect of the high conductivity of graphene and the catalytic activity of nickel oxides promotes the process of glucose oxidation.In this paper, graphene modified anodes are obtained by methods of low costard easy operation, which achieves the effect of replacing electron mediators and improving the overall performance of the fuel cell. Furthermore, this paper provides a basis for the application of graphene in glucose fuel cell.
