Title :
Electrical modeling of PEMFC based on an ID analogic description of mass transport
Abstract :
This article deals with a PEMFC (proton exchange membrane fuel cell) electrical model based on a 1D analog representation of mass transport phenomena. By using an electrical analogy to describe transport of gaseous species in GDLs (gas diffusion layers), and water distribution in the membrane, the model can be directly implemented in standard simulation softwares used in electrical engineering (such as Saber, in our case), so that it can be easily employed for the simulation of fuel cell electrical systems. The paper explains how the analog model is obtained from mass transport equations, then it presents validation tests carried out in both steady-state and transient regimes on a PEM single cell bench.
