[font size=3]PULLMAN, Wash. – Washington State University researchers have developed a novel nanomaterial that could improve the performance and lower the costs of fuel cells by using fewer precious metals like platinum or palladium.
Led by Yuehe Lin, professor in the School of Mechanical and Materials Engineering, the researchers used inexpensive metal to make a super low density material, called an aerogel, to reduce the amount of precious metals required for fuel cell reactions. They also sped up the time to make the aerogels, which makes them more viable for large-scale production.

Aerogels, which are sometimes also called liquid smoke, are solid materials that are about 92 percent air. Effective insulators, they are used in wet suits, firefighting gear, windows, paints and in fuel cell catalysts. Because metal-based aerogels have large surface areas and are highly porous, they work well for catalyzing in fuel cells.
The WSU team created a series of bimetallic aerogels, incorporating inexpensive copper and using less precious metal than other metal aerogels.
