High-temperature (120–200° C) polymer electrolyte membrane fuel cells (HT-PEMFCs) are
promising energy conversion devices that offer multiple advantages over the established …

The gas diffusion layer (GDL) in a proton exchange membrane fuel cell (PEMFC) is one of
the functional components that provide a support structure for gas and water transport. The …

The temperature of operation is a key parameter in determining the performance and
durability of a polymer electrolyte fuel cell (PEFC). Controlling temperature and …

Liquid-gas two-phase flow in the gas diffusion layer (GDL) of proton exchange membrane
fuel cells is investigated using an ex-situ experimental setup. The mass transport …

In this work, a new framework and model for the digital generation and characterization of
the microstructure of gas diffusion layer (GDL) materials with localized binder and …

Liquid water saturation profiles were determined using high resolution neutron radiography
for commercially available fuel cell materials and hardware. Temperature, pressure, and …

Water flooding is detrimental to the performance of the proton exchange membrane fuel cell
(PEMFC) and therefore it has to be addressed. To better understand how liquid water affects …

Water emerging from∼ 100 μm pores into millimeter-size gas flow channels forms drops that
grow and become slugs which span the flow channel. Flowing gas causes the slugs to …

The performance and durability of electrochemical power systems are determined by a
complex interdependency of many complex and interrelated factors, temperature and heat …

Water management is an important issue for proton exchange membrane fuel cells. Back-
diffusion of water from cathode to anode often occurs due to the differences in concentration …
