Scale Up of Extended Thin Film Electrocatalyst Structures (ETFECS) (Fact Sheet)

This NREL Hydrogen and Fuel Cell Technical Highlight discusses how NREL synthesized >1 gram of platinum ETFECS (nanotubes) for use as novel fuel cell catalysts. These materials represent the cumulative yield of four individual batch syntheses (each >250 milligrams yield). By producing these materials at gram quantity, NREL has shown the viability of scale up and produced sufficient material toallow further validation of properties, as well as in-depth electrode optimization and fuel cell testing.
