A newly unveiled catalyst architecture has been designed for low-temperature hydrogen fuel cells. The development could solve a long-standing compromise in clean energy tech: keeping expensive platinum catalysts stable without destroying their power output.

In testing, the researchers led by Gang Wu at Washington University in St. Louis found that the catalyst maintains high performance with minimal precious metal content.

Interestingly, the tech retained 85% of its performance after 150,000 voltage cycles (roughly equivalent to 25,000 hours of operation).
