Jon P. Owejan, T Trabold, Jeffrey J. Gagliardo, Robert N. Carter, Daniel S. Hussey, David L. Jacobson, Muhammad D. Arif
Single fuel cells running independently are often used for fundamental studies of water transport. It is also necessary to assess the dynamic behavior of fuel cell stacks comprised of multiple cells arranged in series, thus providing many paths for flow of

PEM Fuel Cell Membrane Hydration Measurement by Neutron Imaging

D J. Ludlow, M K. Jensen, C M. Calebrese, G A. Eisman, S Yu, C Dannehy, Daniel S. Hussey
Neutron scattering experiments on a proton exchange membrane fuel cell wereperformed to assess the ability to quantify water in the membrane and electrode/gas diffusion layers. Previous studies have shown that liquid water is easily resolved within flow
