Design of experiments on the effects of linear and hyperelastic constitutive models and geometric parameters on polymer electrolyte fuel cell mechanical and electrical behaviour

In this work, the influence of geometric and mechanical properties constitutive layers a Proton Exchange Membrane Fuel Cell (PEMFC) on system performance was investigated. More specifically, study focused internal electrical resistances due to interlayer contacts. Indeed, contact are one main sources ohmic losses in PEMFC therefore require special attention improve efficiency. To end, Design Experiments associated with 2D Finite Element Model including friction developed used. The typology (linear or hyperelastic) law Gas Diffusion Layer (GDL) layer thicknesses were parametrized analysis results shows that impact thickness ratios is more important than GDL law.
