Wisconsin Hydrogen Breakthroughs May Be Steps Toward Cleaner Energy | WUWM
Chemistry professor Shannon Stahl leads a team that designed a fuel cell using cheaper materials and a redesigned compound, which helps the flow of electrons and protons that convert chemical energy into electricity. He says the new process replaces the expensive metal platinum as the catalyst.
“Bypassing the need for platinum would be a major breakthrough. There are strategies that exist right now that are just not meeting the metrics that are needed. And so, conceiving of novel approaches, new strategies to overcome this limitation is really what we’re trying to pursue in this project,” Stahl said.
“Bypassing the need for platinum would be a major breakthrough,” said Shannon Stahl.
Stahl says his research, published this month in the journal Joule, has found that cobalt — a lower-cost metal — can be used instead, with some modifications to the process.
