Proton Exchange Membrane Fuel Cell Lumped Modeling and Simulation

Article Preview

Abstract:

It analyzes in detail the influence factor of voltage of proton exchange membrane fuel cell (PEMFC) when load changes sudden by the lumped modeling developed. The partial pressure of hydrogen and oxygen can be expressed using the ideal gas law equation, and ohmic loss, activation loss and concentration losses are accounted, it is assumed that both operating factor of hydrogen and mixture ratio of hydrogen and oxygen are constant. Based on the above, 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.
