Research conducted by professor Ilhan Aksay at the University’s Ceramic Materials Laboratory, the U.S. Department of Energy’s Pacific Northwest National Laboratory and Washington State University has revealed a way of combining nanoparticles and graphene to develop a material that is more stable and durable for use in fuel cells.
The new process involves wedging platinum between indium tin oxide nanoparticles and a one-atom-thick honeycomb of graphene. Tests showed that the combination increases a fuel cell’s ability to break down oxygen by forty percent compared to just platinum on graphene or just platinum on other carbon supports. The material is also three times more durable than platinum on graphene and twice as durable as activated carbon.
The new material has the potential to make fuel cells cheaper and last longer and is currently being tested on experimental fuel cells.
