The high cost of platinum is one of the main barriers to the wider adoption of hydrogen fuel cells. Now, researchers at IMDEA Materials Institute have developed a catalyst that delivers the same performance while using 75% less of this expensive metal. The study, published in Electrochimica Acta, de monstrates a breakthrough made possible by applying controlled mechanical compression to the catalyst. This modifies its atomic-scale structure, enabling it to achieve energy efficiency comparable to that of pure platinum. ...read more read less
