Fuel crossover and internal current in polymer electrolyte membrane fuel cell from water visualization using X-ray radiography
TL;DR: Using X-ray radiography, the water distribution and membrane swelling, which indicate fuel crossover and internal current, in an operating polymer electrolyte membrane fuel cell under open-circuit conditions were examined in this article.

Breakthrough/drainage pressures and X-ray water visualization in gas diffusion layer of PEMFC
TL;DR: The primary role of the gas diffusion layers (GDLs) in polymer electrolyte membrane fuel cells (PEMFC) is to maintain the delicate balance between water retention and removal in GDLs as mentioned in this paper.

X-ray tomography of morphological changes after freeze/thaw in gas diffusion layers.
TL;DR: A scenario in which freeze/thaw cycles affect fuel cell performance is suggested based on images from X-ray tomography, which shows Morphological changes in the GDL under a water freeze-thaw cycle.
