Comment on “A Look at the Multiphase Mixture Model for PEM Fuel Cell Simulations” [Electrochem. Solid-State Lett., 11, B132 (2008)

Abstract

The article of Gurau et al. discusses the multiphase mixture M2 model developed by Wang and co-workers over the last 15 years for the modeling of multiphase flow through porous media with liquid-vapor phase change. I would like to offer the following comments. 1. All published works on PEM fuel cell PEMFC simulations, based on either the classical multifluid approach e.g., Ref. 19, 20, and 22 in Ref. 1 and numerous others available in more recent literature or the M2 model, use two-phase Darcy’s law as the momentum equation for individual phase motion, which can be specifically written as
