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, demonstrates 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.

Even still, there are a number of issues. The main one being that oil companies are wildly bad at entering new markets

Have they solved the carbon fouling problem yet?
