Tungsten Suboxide Improves Platinum Making Hydrogen
November 19, 2019 | Leave a Comment
Korea’s Advanced Institute of Science and Technology (KAIST) researchers presented a new strategy for enhancing catalytic activity using tungsten suboxide as a single-atom catalyst (SAC). This strategy, which significantly improves hydrogen evolution reaction (HER) in the metal platinum (pt) by 16.3 times, sheds light on the development of new electrochemical catalyst technologies. The research group’s […]

Better Durability For Platinum Fuel Cells
September 11, 2019 | 1 Comment
Georgia Institute of Technology researchers have developed a new platinum-based catalytic system that is far more durable than traditional commercial systems and has a potentially longer lifespan. The new system could, over the long term, reduce the cost of producing fuel cells. Platinum has long been used as a catalyst to enable the oxidation reduction […]

Activity of Platinum Fuel Cells Doubled
July 17, 2019 | Leave a Comment
An interdisciplinary research team at the Technical University of Munich (TUM) has built platinum nanoparticles for catalysis in fuel cells: The new size-optimized catalysts are twice as good as the best process commercially available today. Fuel cells might well replace batteries as the power source for electric cars. They consume hydrogen, a gas which could […]

Fuel Cell With 10 Times the Power With 10% of the Platinum
March 14, 2019 | 2 Comments
Purdue University researchers produce a fuel cell with a new method increasing the fuel cell electrode activity at least tenfold and using 90 percent less platinum. Electric vehicles running on fuel cells tout zero emissions and higher efficiency, but expensive platinum is holding them back from entering a larger market. The 2019 Toyota Mirai electric […]

New Catalyst Beats Platinum in Alkaline Hydrogen Production
February 28, 2019 | Leave a Comment
University of California – Santa Cruz researchers show a novel ruthenium-based catalyst with 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 and carbon to form active sites within the carbon matrix. The […]
