Neutron Imaging, an Essential Tool for the Hydrogen Economy
Most recently this capability at NIST has been highlighted in this excerpt from the President's American Competitiveness Initiative.
Overcoming Technological Barriers to the Hydrogen Economy
NIST research helps support this developing technology in many ways. Projects currently under way at NIST are providing measurements, data, and technologies needed to develop and test the performance of hydrogen-based power sources and to improve the efficiency of hydrogen production methods.
A new imaging facility at the NIST Center for Neutron Research provides a rare portal for visualizing water and hydrogen transport in fuel cells. Neutrons reveal how water forms and moves while a fuel cell is operating. Mastering the combined challenge of managing incoming humidity, proper hydration of fuel cell membranes, and the handling of water byproducts is essential to the development of fuel cells that are practical for automotive and residential applications as well as portable devices.
