Abstract
We present a two-phase, two-dimensional computational model for studying the effect the microporous layer (MPL)and catalyst layer (CL) interface has on the performance of a polymer electrolyte fuel cell (PEFC). The CL vertical bar MPL interface is incorporated as a finite-thickness domain where liquid water saturation levels are determined with van Genuchten water retention curves. These relations are extracted through deterministic contact mechanics model that simulates the three-dimensional interfacial deformation under different levels of compression. Model simulations show high levels of liquid water saturation at the interface that have significant effect on the PEFC performance as opposed to when interfacial contact resistance is included there is a minor performance decrease.
