Nanoparticle technology could create clean, efficient coal-powered fuel cells

Researchers have developed a self-cleaning technique that could allow solid oxide fuel cells to be powered directly by coal gas.

Barium oxide nanostructures adsorb moisture to initiate a water-based chemical reaction that oxidizes the carbon as it forms, keeping the nickel electrode surfaces clean.

“This could ultimately be the cleanest, most efficient and cost-effective way of converting coal into electricity,” Regents professor Meilin Liu said.

This technique could provide a cleaner and more efficient alternative to conventional power plants for generating electricity.
