Abstract

We analyze the impact of the interfacial phenomena at the macroscopic interfaces between fuel cell components on the water management and on the two-phase transport in proton exchange membrane fuel cell (PEMFC) electrodes using multiphase multifluid computational fluid dynamics (CFD). We present the numerical approach used to capture multiphase phenomena at the cathode gas diffusion layer (GDL) - channel interface and explain the mechanisms that trigger the phenomenon referred to as the eruptive water ejection. Notwithstanding that they have been widely ignored, these are phenomena which ultimately control the amount of water that reside in the fuel cell components during operation.
