Transient thermal computation of a PEM fuel cell by a nodal modeling

Abstract

In this paper, the authors propose a thermal modeling of a fuel cell. It has been validated on a 150W power PEMFC. The thermal modeling uses a network of 172 nodes. It takes into account conduction and convection heat fluxes but also mass transfers due to electrochemical reaction. This thermal model is reduced to a global model describing electrical behavior and takes into account temperature regulation of the water cooling system. MATLAB-SIMULINK software has been used. Dirichlet boundary conditions are obtained thanks to a SW infrared camera.

CFD analysis of temperature distribution of PEM type fuel cell

“…components with losses, loss-free components, long-or short heat bars [7,8]. The complex work starts with the very division of the particular components, e.g.…”

Thermal management system modeling of a water-cooled proton exchange membrane fuel cell

“…However, some models are more complex. Dumercy [8,9] proposed a 3D thermal modeling by a nodes network model for two PEMFC of 150 and 500 W to describe the temperature and the heat flux distribution in the fell cell stack. Tiss [10], basing on the theory of heat and mass transfer, proposed a dynamic model for the thermal system of a PEMFC, which showed that the fuel cell temperature is a significant function for manipulative the fuel cell output voltage and gas flow.…”

Thermal modelling approach and model predictive control of a water-cooled PEM fuel cell system

“…Several modelling methodologies have been presented in the literature for Proton Exchange Membrane fuel cells (PEM-FC) with water cooling systems. In [3] a nodal network approach is used to model the thermal behaviour of a 150 W PEM-FC. In [4], both the sensible and the latent heat are taken into account to model the thermal dynamics of a Ballard PEM-FC stack.…”
