An Equivalent Circuit Model of Direct Methanol Fuel Cell for Polarization Analysis PROJECT TITLE :An Equivalent Circuit Model of Direct Methanol Fuel Cell for Polarization AnalysisABSTRACT:This paper presents a gray-box equivalent circuit model (ECM) in order to predict the performance of direct methanol fuel cell (DMFC) unit. The ECM is composed of electronic parts ranging from operational amplifier resistors to diodes. The present-voltage profiles and current-power profiles of this ECM are validated by the simulation results of the COMSOL model. Afterward, the influences of methanol concentration, operating temperature, and oxygen concentration on the performance of the one passive DMFC are all validated experimentally. All validations show that the ECM provides a good approximation of the behavior of the DMFC. In addition, a simulated application of a circuit system using the ECM is explained. The simulated result's validated experimentally. This analysis makes it attainable to investigate the behavior of a DMFC in real applications. Did you like this research project?
