In situ neutron imaging of operating Polymer Electrolyte Fuel Cells (PEFCs) has been increasingly used in the past 10 years in order to visualize and quantify the distribution of liquid water. The Paul Scherrer Institute (PSI) could bring an important contribution to this field, thanks to the long term collaboration between the Electrochemistry Laboratory (ECL) and the Neutron Imaging and...

Monochromatic neutron beams or neutrons corresponding to a small wavelength band close to Bragg-edges are used to discriminate between different phases of materials or to gain a spatially resolved map of stress and strain inside a sample.
Standard neutron radiography and tomography experiments on the contrary are acquired with a white neutron beam most of the time. This is done in order to...

Neutron imaging is a valuable tool for in situ characterizations, similar to x-ray radiography. Using time series of neutron images, the change in attenuation of a neutron beam passing through a sample can be used to follow a change in the material over time. The utilization of neutron imaging for fuel cell liquid water metrology has been demonstrated at PSI [1] and NIST [2]. A similar...
