'Goldilocks' Thinking to cut Fuel Cell Cost in EVs

A platinum-like metal only five atomic layers thick is "just right" for optimizing the performance of a fuel cell electrode.

WEST LAFAYETTE, Ind. -- The 2019 Toyota Mirai electric vehicle touts zero emissions, thanks to a fuel cell that runs on hydrogen instead of gasoline. But the Mirai has barely left California, partly because today's fuel cell electrodes are made of super expensive platinum. Cutting down on the platinum would also

Electrocatalyst Outperforms Platinum in Hydrogen Production

The novel catalyst is a nanostructured composite material composed of carbon nanowires with ruthenium atoms bonded to nitrogen and carbon to form active sites within the carbon matrix. Electron microscopy of carbon nanowires co-doped with ruthenium and nitrogen showed ruthenium nanoparticles decorating the surface of the nanowires.

A novel ruthenium-based catalyst developed at UC Santa Cruz has shown markedly better performance than commercial platinum catalysts in alkaline water electrolysis for hydrogen production. The catalyst is a nanostructured composite material composed of carbon nanowires with ruthenium atoms bonded to nitrogen an

Observing Hydrogen's Effects in Metal
Hydrogen, the second-tiniest of all atoms, can penetrate right into the crystal structure of a solid metal. That's good news for efforts to store hydrogen fuel safely within the metal itself, but it's bad news for structures such as the pressure vessels in nuclear plants, where hydrogen uptake eventually makes the v
