摘要
Improvements in the spatial resolution of neutron imaging were specifically developed for application in fuel cell imaging, where the resolution requirement in different directions may vary by 1 order of magnitude, thus making anisotropic setups attractive. A maximal spatial resolution of 8.7 mu m could be reached. For the transient studies, the combination of a high resolution of 20 mu m with exposure times of 10 s proved to resolve the water evolution, both temporally and spatially.
