[email protected] features @ORNL @LosAlamosNatLab work on low-cost fuel cell catalysts

ORNL, LANL study provides insights into performance of non-precious metal fuel-cell catalysts; atomic-level observations 4 August 2017 In order to reduce the cost of next-generation polymer electrolyte fuel cells for vehicles, researchers have been developing alternatives to the prohibitively expensive platinum and platinum-group metal (PGM) catalysts currently used in fuel cell electrodes. New work at Los Alamos (LANL) and Oak Ridge national laboratories (ORNL) is now resolving difficult fuel-cell performance questions, both in determining efficient new materials and understanding how they work at an atomic level. The research is described this week in the journal Science . Building on previous studies, the Los Alamos-led team has synthesized catalysts comprising low-cost platinum alternatives—iron-nitrogen-carbon catalysts synthesized with two nitrogen precursors that de...
