  • Carbon-coated iron catalyst structure could lead to more-active fuel cells

    Illinois professor Andrew Gerwith and graduate student Jason Varnell developed a method to isolate active catalyst nanoparticles from a mixture of iron-containing compounds, a finding that could help researchers refine the catalyst to make fuel cells more active.
