Cornell University successfully synthesized a novel thin-film catalyst for fuel cells

Recently, Cornell University researchers synthesized a new thin-film catalyst
for fuel cells.
The research team reports the first epitaxial growth of Bi2Pt2O7 pyrochlore film, which can serve as a more efficient cathode, the basic electrode part in fuel cells, from which positive charge flows to the outer circuit and transfers electrical energy
.

Araceli Gutierrez-Llorente, leader of the research team, said that until now, oxygen catalyst films applied to clean energy have focused on perovskite structural oxides
and their derivatives.
Cubic pyrochlore structures are an attractive alternative to perovskite structures for applications such as fuel cell cathodes, but little research has been done in this area
.

Gutierrez-Llorente said that synthetic thin-film materials, instead of bulk powders, open up new possibilities
for fuel cell applications.
A large number of exotic properties cannot be expressed in the block, but can be produced
between the interfaces of complex oxides of the film.
