Researchers have developed a new catalyst design capable of pushing the projected fuel cell catalyst lifespans to 200,000 hours. The research marks a significant step toward the widespread adoption of fuel cell technology in heavy-duty vehicles, such as long-haul tractor trailers. While platinum-alloy catalysts have historically delivered superior chemical reactions, the alloying elements leach out over time, diminishing catalytic performance. The degradation is further accelerated by the demanding voltage cycles required to power heavy-duty vehicles. To address this challenge, the team has engineered a durable catalyst architecture with a novel design that shields platinum from the degradation typically observed in alloy systems.
