1. A fuel cell comprising a core-shell nanostructure, wherein the core-shell nanostructure comprises a palladium nano-substrate conformally coated with between one and ten continuous uniform and smooth atomic overlayers of epitaxially deposited zero-valent platinum atoms over the whole surface of the palladium nano-substrate, wherein the palladium nano-substrate has a shape selected from the group consisting of cubic, concave cubic, tetrahedral, bipyramidal, octahedral, icosahedral, decahedral, rod, bar, and wire.
