Based on the model of a single PEMFC that includes four control volumes, i.e. cooling channel, anode/cathode gas channel, MEA and so on, a mathematical method was introduced to describe reactants pressure, water content and temperature which were related with the cell position, and furthermore, a semi-empire dynamical stack model was developed to demonstrate performance differences among single cells. According to the model, dynamic characters of some important physical quantities of the stack (include temperature, water content, voltage, etc.) under special working conditions (such as start-up, braking, and idle conditions, etc.) were analyzed in detail.
