We report on measured neutron cross section data for super-cooled water and ice by time-of-
flight (TOF) neutron transmission imaging. In particular, we demonstrate the use of high duty …

In this study, the cold-start failure processes of a polymer electrolyte fuel cell have been
investigated numerically for different initial membrane water content λ 0 and the startup …

Enhancing the cold start ability of proton-exchange membrane fuel cells (PEMFCs) can
widely apply fuel cells in a cold environment. In this study, PEMFC cold start performance …

The success of a freeze start of a polymer electrolyte fuel cell depends on the state and
spatial distribution of the water produced in the porous structures of the membrane electrode …

The structure, composition, and interfaces of membrane electrode assemblies (MEA) and
gas-diffusion layers (GDLs) have a significant effect on the performance of single-proton …

In this paper, we present experimental results about the influence of a hydrophobic coating
of gas diffusion layers (GDL) and the existence of a micro porous layer (MPL) on the cold …

Starting PEFCs from sub-zero temperatures can be challenging as generated product water
runs the risk to freeze, causing cell failure by blocking the gas pathways for the reactant …

Automotive subzero cold-starts are challenging for proton exchange membrane fuel cells
(PEMFCs) and depend on material structure and initial water content (λ initial). PEMFC cold …

Subzero cold-starts are one of the last remaining challenges to the commercialization of
automotive fuel cells. The ultimate cold-start target is to exothermically self-start a fuel cell …

In this study, the cold-start process of a polymer electrolyte fuel cell has been numerically
investigated under various ambient temperatures and operating currents, ranging from …
