Abstract

This invention provides a method for calculating the fuel concentration used in a Direct Methanol Fuel Cell (DMFC). The method comprises the steps of: providing a DMFC; providing plural and different fuels with known concentrations to the DMFC, and making the DMFC produce electrochemical reaction to generate electricity under the condition of each different known fuel concentration; respectively measuring and recording a plurality of physical parameters corresponding to different kinds of the preset fuel concentrations that are individually reacted in the DMFC, and selecting three of the recorded physical parameters to construct a relative three-dimensional measured space; performing interpolation according to the three-dimensional measured space; and when fuel with unknown concentration is applied in the DMFC to produce an electrochemical reaction and generate electricity, measuring at least three physical parameters and performing interpolation to determine the present fuel concentration in the DMFC.
