Researchers from Institute of technology of Georgia, the USA, synthesized the catalyst from nanocrystals of Pt-Ni (platinum-nickel). The catalyst possesses record-breaking high activity in relation to reaction of restoration of oxygen (ORR). Let’s note that low catalytic activity concerning ORR is considered one of the main obstacles for successful commercialization of fuel elements on a basis. Fuel elements on the basis of proton changing membranes have high efficiency of transformation of energy that allows to replace with them petrol and diesel engines of an internal combustion engine. Unfortunately, assembly of fuel elements of the power accepted for commercial use, reliability and durability requires considerable amount of expensive metal – platinum. Therefore to make PEMFC suitable for large-scale commercialization, are necessary new more effective catalysts. By calculations of specialists of the Ministry of an energy drink of the USA, activity of the catalyst in relation to reaction of restoration of oxygen has to be increased approximately by 3–4 times that will allow to reduce amount of used platinum at preservation of present efficiency of fuel cells.
Pamela Silver, a Harvard scientist, is working on deriving biofuel from the deep-ocean extremophiles bacteria. U.S. Department of Energy is funding Pamela Silver’s team to find out bacteria, other than the known e-coli, yeast, or even photosynthetic bacteria, which can be used for producing biofuel.
