What to know about New catalyst with 75% less platinum promises to reduce the cost of hydrogen fuel cells

Researchers at the IMDEA Materials Institute have developed a copper-platinum alloy catalyst that uses 75% less platinum than pure platinum catalysts while maintaining similar performance. The study, published in Electrochimica Acta, utilizes mechanical compression to enhance energy efficiency, though the authors note that industrial scalability and long-term stability still need to be addressed.

What happened

New catalyst with 75% less platinum promises to reduce the cost of hydrogen fuel cells Lisa Lock Scientific Editor Robert Egan Senior Editor The high cost of platinum is one of the main barriers to the wider adoption of hydrogen fuel cells.

Why it matters

Now, researchers at IMDEA Materials Institute have developed a catalyst that delivers the same performance while using 75% less of this expensive metal.

Common ground

The study, published in Electrochimica Acta, demonstrates a breakthrough made possible by applying controlled mechanical compression to the catalyst.
