▎ 摘　　要

NOVELTY - A fuel cell comprises core-shell nanostructure. The core-shell nanostructure comprises 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. The palladium nano-substrate has a shape chosen from cubic, concave cubic, tetrahedral, bipyramidal, octahedral, icosahedral, decahedral, rod, bar, and wire. USE - Fuel cell e.g. proton exchange membrane fuel cell (claimed). ADVANTAGE - The fuel cell contains core-shell nanostructure with improved long-term stability.
