NIST scientist David Jacobson prepares an experimental fuel cell for real-time imaging at the NIST Center for Neutron Research. A new research station at the center produces still images akin to CAT scans and movies recorded at a rate of up to 30 frames per second, or 30 times faster than a first-generation instrument. ©Robert Rathe

Thanks to a new and improved imaging instrument at the Commerce Department’s National Institute of Standards and Technology (NIST), scientists now can conduct detailed surveillance on the comings and goings of water inside hydrogen fuel cells—a piece of intelligence key to making the technology practical for powering future automobiles.
