Recent In Situ High-Resolution Neutron Radiography Experiments of PEMFCs

RECENT IN SITU HIGH-RESOLUTION NEUTRON RADIOGRAPHY EXPERIMENTS OF PEMFCS 

The improved neutron detector spatial resolution has been a recent advance, with user instruments first available at the end of 2006 and 2007 at NIST and PSI, respectively. The work can be classified as proof-of-principle,9,10 in situ measurement of the steady-state through-plane water content during fuel cell operation, 13 and dynamic through-plane mass transport measurements.14,15
