Abstract

This paper focuses on the thermal modelling of a CHP system based on Proton Exchange Membrane Fuel Cell (PEMFC) by experimental analysis and analytical relationships. To this end, there have been carried out several experimental tests on a PEMFC 600 W of electrical power in order to obtain the necessary data for thermal modelling and its subsequent validation. Once made the experimental analysis, data obtained have been used to develop the thermal model of the stack of the fuel cell as well as the entire temperature management system, by implementing various analytical relationships in the MATLAB/Simulink environment. The model obtained has allowed to characterize the thermal behaviour of the fuel cell to different profiles of electrical and thermal energy demand, with a minimum and maximum relative error in the temperature of the stack of 3.77% and 11.05%, respectively.
