A method for constructing a starch fuel cell with an anode belongs to the field of fuel cells. The method includes using a PdNFs/FeNPs/MFC electrode as a working electrode, an Ag/AgCl electrode as a reference electrode, and a platinum wire as an auxiliary electrode to form a three-electrode system. The method includes placing the three-electrode system in a starch solution and a supporting electrolyte; setting the potential as −0.2 to 1.3V. The method includes recording the cyclic voltammetry curves of the starch with concentrations of 1 mmol/L, 3 mmol/L, 5 mmol/L, 7 mmol/L, and 10 mmol/L. The method includes analyzing the control process of the electrode electrocatalytic oxidization of the starch solution by the standard curve method. The present fuel cell can be used to manufacture portable power banks, and can be used in power plants, electric vehicles and other fields.
