to make modern-day fuel cells less expensive and more powerful . . . a team led by Johns Hopkins chemical engineers has drawn inspiration from the ancient Egyptian tradition of gilding. . . . In a modern-day twist, the Johns Hopkins–led researchers have applied a tiny coating of costly platinum just one nanometer thick—one hundred thousand times thinner than a human hair—to a core of much cheaper cobalt. This microscopic marriage could become a crucial catalyst in new fuel cells that generate electric current to power cars and other machines.

The new fuel cell design would save money because it would require far less platinum, a very rare and expensive metal that is commonly used as a catalyst in present-day fuel-cell electric cars, an alternative to battery-powered vehicles By making electric cars more affordable, this innovation could curb the emission of carbon dioxide and other pollutants from gasolineor diesel-powered vehicles. [Chao Wang, a Johns Hopkins assistant professor in the department of chemical and biomolecular engineering and his research team members,] tipped their hats to the ancient Egyptian artisans, who used a similar plating technique to give copper masks and other metallic works of art a lustrous final coat of silver or gold.20
