This tiny iron catalyst could transform the future of clean energy

Hydrogen fuel cells could power cars, devices, and homes with nothing but water as a byproduct—but platinum’s cost holds them back. Chinese researchers have now unveiled a breakthrough iron-based catalyst that could rival platinum while boosting efficiency and durability. With its clever “inner activation, outer protection” design, this new catalyst not only reduces harmful byproducts but also shatters performance records, potentially paving the way for cleaner, cheaper, and more practical hydrogen energy.
