[font size=5]CWRU researchers bring clean energy a step closer[/font]
[font size=4]Cheaper, more durable catalyst for fuel cell used in cars, at data centers[/font]
Case Western Reserve University
[font size=3]For nearly half a century, scientists have been trying to replace precious metal catalysts in fuel cells. Now, for the first time, researchers at Case Western Reserve University have shown that an inexpensive metal-free catalyst performs as well as costly metal catalysts at speeding the oxygen reduction reaction in an acidic fuel cell.
The carbon-based catalyst also corrodes less than metal-based materials and has proved more durable.
The findings are major steps toward making low-cost catalysts commercially available, which could, in turn, reduce the cost to generate clean energy from PEM fuel cells--the most common cell being tested and used in cars and stationary power plants. The study will be published online in the journal Science Advances at 2 p.m. U.S. Eastern Time Friday, Feb. 27.
"This definitely should move the field forward," said Liming Dai, the Kent Hale Smith Professor of macromolecular science and engineering at Case Western Reserve and senior author of the research. "It's a major breakthrough for commercialization."
