Proton Exchange Membrane Fuel Cell(PEMFC) Heat Transfer Model and Dynamic Heat Response Analysis
A heat transfer model of PEMFC is developed that captures dynamic behavior for control purposes in this paper. According to the law of conservation of energy, by analyzing in detail the heat source, considering the heat of electrochemistry, activation polarization heat and the heat loss of air forced convection etc., the dynamic heat model of PEMFC is established. Among all influential factors of fuel cell temperature, current density is one of the most important influence factors. Finally, by comparing the response results temperature with the current density changes between simulation and experiments, the results s are consistent. The model in this article has an important guiding significance for the design of fuel cell. For example, the working temperature of fuel cell can keep up stability by controlling cooling medium flow rate etc.
