In this article, a two-dimensional, multiphase, transient model is introduced and used to
explore the impact of catalyst-layer thickness on performance. In particular, the tradeoffs …

In this study, the lattice Boltzmann method (LBM) is used to investigate liquid water transport
in the microporous layer (MPL) and gas diffusion layer (GDL) of polymer electrolyte …

In-situ observation of liquid water transport in the microporous layer (MPL) and gas diffusion
layer (GDL) of an operating proton exchange membrane fuel cell (PEMFC) was performed …

We present a study on a new type of flow field channel design for polymer electrolyte
membrane fuel cells (PEMFCs). Small barriers have been implemented into the flow field …

The penetration of microporous layers (MPL) into gas diffusion layers (GDL) is a common
phenomenon in proton exchange membrane (PEM) fuel cells. However, research on this …

Polymer electrolyte membrane fuel cell performance has been enhanced with efficient water
management by modification of the structure of the catalyst layer. Polytetrafluoroethylene …

A two-dimensional, along-the-channel, two-phase flow, non-isothermal model is developed
which represents a low temperature proton exchange membrane (PEM) fuel cell. The model …

This work uses neutron radiography to examine the through-plane liquid water distribution of
an operating polymer electrolyte membrane fuel cell (PEMFC) with a Sigracet SGL 25BC, a …

In this study, Polytetrafluoroethylene (PTFE) was added to catalyst layer structure. This
modification was aimed at facilitating excess water removal from the cathode catalyst layer …
