Scientists have developed a method to enhance the stability of iron-based catalysts used in hydrogen fuel cells. This advancement addresses a long-standing challenge that has limited the durability of low-cost iron catalysts compared to traditional platinum ones. The new approach enables these iron catalysts to achieve up to 85% fuel efficiency.
The improved stability could allow iron catalysts to replace expensive platinum in hydrogen fuel cells, potentially reducing costs and increasing the accessibility of clean energy technologies. This breakthrough may accelerate the adoption of hydrogen as a sustainable fuel source.
**Why this matters**
Hydrogen fuel cells are a promising clean energy technology, but their widespread use has been hindered by the high cost of platinum catalysts. By stabilizing cheaper iron catalysts without sacrificing efficiency, this development could lower production costs and support the growth of hydrogen-powered vehicles and energy systems.
