Dutch University Discovers How to Reduce Platinum Use in Fuel Cells

Annika Tostengard — Mon, 12 Oct 2015 05:21:58 +0000

Researchers from Tufts University have discovered a way to make fuel cells cheaper by using less platinum. Platinum is used as a catalyst in fuel cells, inducing the chemical reactions that make green technology like electric vehicle batteries work. Platinum, however, is extremely scarce and so using it in any technologies generally prohibits them from being very […]

Scientists Use Palladium as Core to New Hydrogen Fuel Cell-Improving Nanoparticle

Hydrogen fuel cells generate electricity when fed with hydrogen, which combines with oxygen and results water. Still, hydrogen fuel cells are expensive due to the catalyst used in the cathode for the reaction known as oxygen reduction. That catalyst is 100% pure platinum, which is a rare and expensive material.

Fuel cells are indispensable for hydrogen powered cars, and it looks like hydrogen may be the ultimate energy storage that meets all the demands of a clean "fuel" (though it's only a carrier, not a fuel). Fuel cells, are expensive, though, and their price is due to platinum, which is a rare metal.

Researchers from Brigham Young University have a plan to make different fuel cells than those we actually know, and turn them into something very efficient and reliable. Their goal is to make a cheap fuel cell with a cheap catalyst, which can be even more efficient than a PEM and which can use something easier to make and store than hydrogen and which has no net emissions.

ACAL Energy Ltd. has broken a new record in fuel cell output power with a liquid platinum-free cathode system. The scientists from ACAL Energy obtained, from a development proton exchange membrane (PEM) fuel cell using platinum-free cathode technology, a peak power that constantly exceeded 570mW/cm2.
