roton exchange membrane fuel cells (PEMFCs), often referred to as "hydrogen power banks," are clean energy devices that generate electricity from hydrogen and oxygen with only water as a byproduct. Characterized by high efficiency, rapid start-up, and zero emissions, they hold great promise in transportation, portable electronics, and stationary power generation. Unfortunately, PEMFCs currently rely heavily on scarce and expensive platinum as a catalyst, making their widespread adoption impractical.
Now, however, a team of Chinese scientists has developed a high-performance iron-based catalyst for these fuel cells that could potentially reduce reliance on platinum. The new design, described as "inner activation, outer protection," enables record efficiency and long-term durability.
The findings were published in Nature.
