More wins DOE Hydrogen and Fuel Cells Program R&D Award

Karren More

Karren L. More of the Materials S&T Division has received the 2013 DOE Hydrogen and Fuel Cells Program R&D Award in recognition of outstanding achievements in leading ORNL's project on Microstructural Characterization of Fuel Cell Materials and in her role as a subcontractor on multiple DOE-funded fuel cell R&D projects.

Karren's experience with a variety of electron microscopy techniques has enabled unprecedented levels of characterization of a variety of materials used in catalysts, supports, ionomers, gas diffusion layers, and membranes. She has collaborated on numerous fuel cell durability and aging studies with other national laboratories (including Los Alamos, Brookhaven, Argonne and NREL) and leading manufacturers such as 3M, General Motors, Ballard, AFCC, Nissan, Nuvera, and UTC.

Her work correlates microstructural/compositional observations with accelerated stress test protocols and "real world" fuel cells, especially related to catalyst coarsening and migration, carbon corrosion and membrane degradation.
