New high-activity, low-cost nickel-based catalyst for fuel cells exhibits performance similar to Pt; hydroxide exchange membrane fuel cells

Green Car Congress

Researchers at the University of Delaware, with a colleague at the Beijing University of Chemical Technology, have developed a composite catalyst—nickel nanoparticles supported on nitrogen-doped carbon nanotubes—that exhibits hydrogen oxidation activity in alkaline electrolyte similar to platinum-group metals.

New low-cost bio-inspired nanostructured MoS2 catalyst performs almost as efficiently as Pt for hydrogen production

Green Car Congress

A team led by researchers from Sandia National Laboratories and the University of California, Merced has developed an efficient molybdenum disulfide (MoS 2 ) catalyst for driving the hydrogen evolution reaction (HER). Work at UC Merced was supported by a university startup fund. —Chen et al. Resources.

New nanoparticle copper compound cathode could enable low-cost, long-life and high-power potassium-ion batteries for grid storage

Green Car Congress

Stationary energy storage systems that can operate for many cycles, at high power, with high round-trip energy efficiency, and at low cost are required. Cost is a greater concern. We decided we needed to develop a new chemistry if we were going to make low-cost batteries and battery electrodes for the power grid.

Who Will Free EV Motors from the Rare Earth Monopoly?

Cars That Think

Ayman El-Refaie, Marquette University Now a sleeper option, synchronous reluctance motors , is getting a surge of interest, thanks to materials-science breakthroughs at GE Aerospace. GE Aerospace declined to make a researcher available to be interviewed for this article.) I am a believer that this type of material is a game changer.”
