Resumen:
Several model methodologies have been presented in the literature for Proton Exchange Membrane Fuel Cells (PEM-FC) with water cooling systems. In [1] a nodal network approach is used to model the thermal behavior of a 150W PEM-FC. This model computes the internal temperature and the outlet temperature of the gas channel and cooling water. In [2], both the sensible and the latent heat is taken into account to model the thermal dynamics and steady state of a Ballard PEM fuel cell stack. The only computed temperature is the stack temperature as a single mass, but it does not take into account the individual cell temperatures. In [3], a model for a single cell is presented, it also incorporates the variation of the outlet water. In [4], a 3-D nodal modeling approach is used and implemented using parallel computing in order to have a precise result by dividing the stack in several nodes …
