An Analytical and Experimental Study on Coolant Flow and Temperature Distribution within Pem Fuel Cell Stack

Abstract:

In the present study, a mathematical model is developed for investigation of coolant flow and temperature distribution within PEMFC stack. The model consists of two main sub models: (1) a coolant flow distribution model, which is used to determine the coolant mass flow distribution between different cooling flow fields of the fuel cell stack; and (2) a thermal model, which computes the coolant temperature increase along the flow field and also the temperature distribution within each cell of the stack. By using this model, optimized amount of effective parameters on stack coolant flow and temperature distribution could be obtained with respect to lower pressure drop along the manifolds and flow fields and more stack temperature uniformity. Test results of a 65-cells stack are presented to verify the simulation results.
