Aerogel catalyst shows promise for fuel cells

(Phys.org)—Graphene nanoribbons formed into a three-dimensional aerogel and enhanced with boron and nitrogen are excellent catalysts for fuel cells, even in comparison to platinum, according to Rice University researchers.

Cheap hybrid outperforms rare metal as fuel-cell catalyst

(Phys.org) —Graphene quantum dots created at Rice University grab onto graphene platelets like barnacles attach themselves to the hull of a boat. But these dots enhance the properties of the mothership, making them better ...

Materials scientists create stronger cobalt for fuel cells

A multi-institutional research team led by materials scientists from Pacific Northwest National Laboratory (PNNL) has designed a highly active and durable catalyst that doesn't rely on costly platinum to spur the necessary ...

Spinach: Chemistry experiments show potential to power fuel cells

"Eat your spinach," is a common refrain from many people's childhoods. Spinach, the hearty, green vegetable chock full of nutrients, doesn't just provide energy in humans. It also has potential to help power fuel cells, according ...

Platinum-free catalysts could make cheaper hydrogen fuel cells

The high cost of platinum catalysts used in hydrogen fuel cells limits the commercialization of fuel cell electric vehicles. Scientists are studying alternative catalysts to increase cost-effectiveness and maintain efficiency ...

Researchers provide new method to boost clean energy research

Electrochemical energy systems—processes by which electrical energy is converted to chemical energy—are at the heart of establishing more efficient generation and storage of intermittent energy from renewable sources ...

Noble metal-free catalyst system as active as platinum

Industry uses platinum alloys as catalysts for oxygen reduction, essential in fuel cells and metal-air batteries, among other applications. Expensive and rare, that metal imposes tight restrictions on manufacture. Researchers ...
