NOVELTY - Preparation of high power flexible single enzyme glucose fuel cell includes dissolving bismuth (III) nitrate pentahydrate and sodium fluoride in water, mixing, adding tetrabutyl titanate solution, mixing, synthesizing in water, washing, drying to obtain bi3ti2o8f powder, mixing reduced graphene oxide (rGO) powder and polytetrafluoroethylene (PTFE) solution to obtain carbon paste, sending mixed solution to polytetrafluoroethylene film, pressing, drying to obtain PTFE/rGO flexible electrode, mixing glucose oxidase (GOD) solution and Bi3Ti2O8F chitosan solution, adding mixture on the surface of PTFE/rGO flexible electrode, fixing enzyme with 0.5 wt.% Nafion solution (RTM: perfluoro-sulfonic acid polymer), drying at 4 degrees C to obtain Nafion/GOD/Bi3Ti2O8F/rGO flexible electrode, using Nafion/GOD/Bi3Ti2O8F/rGO flexible electrode as biological anode, PTFE/rGO flexible electrode as cathode, glucose as fuel and constructing 3D Bi3Ti2O8F/rGO flexible glucose fuel cell. USE - The method is for preparation of high power flexible single enzyme glucose fuel cell. ADVANTAGE - The method does not need a diaphragm. The fuel cell has large open circuit voltage and power density, 0.6 V output voltage and 650 ~MW cm-2 output power density.
