UCF Professor Sergey Stolbov and postdoctoral research associate Marisol
Alcántara Ortigoza developed a structure that makes gold and palladium better
for hydrogen fuel cells. They built a top layer of gold or palladium over a
layer that enhances the energy conversion rate of the fuel cell that also
protects the catalyst from the acidic environment. These two layers are placed
on top of a layer made of inexpensive tungsten substrate which also acts to
stabilize the catalyst.
"We are very encouraged by our first attempts that suggest that we can create
two cost-effective and highly active palladium- and gold-based catalysts -for
hydrogen fuel cells, a clean and renewable energy source," Stolbov said.
According to the researchers the structure they developed allows more energy to
be converted while reducing the cost as more inexpensive metals are used. More
experiments are needed to test if their structure has the potential for
large-scale production. They are already working with a group within the U.S.
Department of Energy to duplicate the results.
