Researchers from Cornell University have developed a way to synthesize a new thin-film catalyst to improve efficiency and effectiveness in fuel cells.

For the first time ever, researchers were able to explain the epitaxial thin-film growth of a fundamental electrode component of the fuel cell, which could result in a more effective cathode.

“Up to now, research on oxygen catalysts in thin film form for clean-energy applications has been focused on the perovskite-structured oxides and their structural derivatives,” said lead researcher Araceli Gutierrez-Llorente. “The much less studied cubic pyrochlore structure is an appealing alternative to perovskites for such applications as fuel cell cathodes.”

This from American Institute of Physics:

The pyrochlore in question—Bi2Pt2O7—has previously been successfully synthesized as a nanocrystalline powder. Epitaxial thin films can actually act as more efficient fuel cell catalysts than nanocrystalline powder, but growing Bi2Pt2O7 directly as a film requires oxidizing the platinum metal—a challenging step.

This development opens up new possibilities for fuel cell technology.
