The article discusses research led by Younan Xia of Washington University on platinum as a catalyst for fuel cells. The research team developed a technique for growing tiny platinum structures on small palladium seeds called nanodendrites which exposed a high amount of surface area on the platinum....
"If you're given only a very small amount of platinum in the first place, you have to make the best use of it," said Argonne chemist Di-Jia Liu, the corresponding author of the study. "To use a platinum-cobalt core-shell alloy allows us to make larger number of catalytically active ...
Fuel cells represent an important component of the energy transition, as they supply electrical energy without first having to create heat and steam from fossil fuels. Instead, they create the energy directly from a reaction of hydrogen and oxygen to form water. For that reason, they can create...
Platinum is one of the most commonly used catalysts for fuel cells because of how effectively it enables the oxidation reduction reaction at the center of the technology. But its high cost has spurred research efforts to find ways to use smaller amounts of it while maintaining the samecatalytic...
“Hypermec™”) for fuel cells. Their compositions are proprietary but they contain cobalt and nickel and some contain also a “reduced” quantity of platinum. They function in PMFCs, DMFCs, and similar cells using ethanol. Acta has just signed an exclusive distribution agreement for these ...
group at the University of Birmingham in England is looking at using microbes to produce "biohydrogen" from waste, and claim their technology has an added bonus - leftover enzymes can be used to scavenge precious metals from spent automotive catalysts that can then be used to make fuel cells....
Lots of work is being done right now by scientists around the globe to make hydrogen fuel cells a more feasible replacement for gasoline and diesel engines. We recently reported that researchers had devised a way to remove all carbon monoxide from the hydrogen power generation process, which, ...
For these processes, it has filed for more than 20 patent families. And not only at the end of the product lifecycle is resource conservation the focus: in the future, it is planned to use digital twins to monitor the service life and function of the components in fuel cells and in elec...
Usage Evaporation source, jewelry production, electrical contacts for semiconductors. Usage Platinum sputtering target is used to make weights and measures standards, electronics industry for electrical contacts, and it is used to manufacture electrodes, manufacture jewelry and also used as catalyst.10...
Platinum-based PEM technology could be a powerful tool in the energy transition, making clean hydrogen and fuel cells more competitive. However, unless action is taken to address the supply-demand gap, scarcity of this precious metal could threaten decarbonization goals. ...
