Researchers Boost Fuel Cell Robustness and Sustainability with Cobalt-Modified Nanomaterial
A research team from the University of Western Ontario has developed a cobalt-modified nanomaterial that significantly enhances the durability and sustainability of proton-exchange membrane fuel cells (PEMFCs). These fuel cells have shown promise for energy production but have long suffered from issues related to durability and cost.
The cobalt-modified nanomaterial improves the oxygen reduction reaction (ORR) within the fuel cells, leading to higher efficiency in power generation while reducing the reliance on costly platinum, a precious metal sourced primarily from South Africa. After subjecting the new catalyst to 20,000 cycles of an accelerated durability test, it displayed remarkable stability, with only a two percent loss in initial activity.
The research has implications for advancing sustainable energy solutions and reducing the dependence on precious resources in the fuel cell industry.
