Proton Exchange Membrane Fuel Cell Lumped Modeling and Simulation
A model of a PEMFC is developed that captures dynamic behavior for control purposes.It analyzes in detail the influence factor of voltage of proton exchange membrane fuel cell (PE.MFC).The model is mathematically simple,and accounts for the essential phenomena that influence the PEMFC performance.The partial pressure of hydrogen and oxygen can be found using the ideal gas law equation,and then the steady lumped mathematical model of PEMFC is established in this paper.On the basis of the above,it is assumed that both operating factor of hydrogen and mixture ratio of hydrogen and oxygen are constant,the dynamic lumped model of PEMFC is proposed.The correctness of model is verified by comparing the experiment data with simulation result of model.The research about lumped model has important significance to the research of the distributed generation network in various performances and has guiding meaning to the fuel cell structure design.
