Fuel cell with optimized design for high durability<\/h2>\n\n

The new catalyst developed by the team led by Prof. Yu Huang employs pure platinum protected by graphene cavities embedded in a porous carbon matrix (Ketjenblack). This architecture avoids the degradation typical of platinum alloy catalysts<\/strong>, improving both stability and efficiency under demanding conditions. <\/p>\n\n

During accelerated tests simulating extended use conditions, the system showed a power loss of less than 1.1% after 90,000 voltage cycles. These results far exceed current U.S. Department of Energy standards<\/strong>, which target 30,000 hours for fuel cell systems by 2050. heavy-duty fuel cell systems.<\/a><\/strong> heavy-duty fuel cell systems. <\/p>\n\n

Viable alternative to electric batteries<\/h2>\n\n

Unlike batteries, fuel cells fuel cells<\/a><\/strong> are lighter and offer refueling times comparable to gasoline. Their lighter weight and higher energy density make them ideal for long-haul trucks<\/strong>, allowing long hauls without sacrificing cargo capacity. <\/p>\n\n

Medium and heavy trucks represent only 5 % of the vehicle fleet, but generate about 25 % of the transport sector’s emissions. Adopting this new technology could significantly reduce greenhouse gas emissions. greenhouse gas emissions.<\/a><\/strong>. In addition, the implementation of a hydrogen infrastructure could require less investment than a national electric charging network. <\/p>\n\n

A solid foundation for the future of mobility<\/h2>\n\n

This development builds on previous UCLA advances in catalysts for light-duty vehicles, where they had already exceeded DOE goals. Now, with this heavy-duty innovation, the door is open to a real transition to cleaner, more sustainable transportation. <\/p>\n\n

The work was published in Nature Nanotechnology<\/a><\/strong> and involved researchers from UC Irvine. In addition, the university has applied for a patent to protect this innovative technology. <\/p>\n\n
