Scientists develop new catalysts for fuel cells

Methanol fuel cell is an alternative to fossil fuel cells, efficient use can be a long time. The fuel cell through the use of electro-oxidation of the chemical reaction to produce electricity. Typically, the induced chemical reactions inside a fuel cell requires platinum catalyst, as platinum is an expensive metal, so the use of this technology is very limited. It is reported that chemists Jose E Barranco will likely change this situation. According to his research, the use of cheaper fuel cell catalysts has been developed. Barranco with nickel, niobium, antimony and ruthenium as a catalyst made of alloy, the content of platinum in the catalyst to a minimum (only l%). The new alloy also improves the catalytic process of carbon monoxide, carbon dioxide conversion. With the successful test catalysts, Barranco want to experiment more in-depth, the efficiency of the catalyst increased 9-13 times. This also means that the efficiency of methanol fuel cells will be increased by 50% or more.

Thin film solar cell development in Tianjin has been a major breakthrough

Recently, from the Nankai University and Tianjin Bonded Zone Investment Company, Professor Sun Yun research group to develop the Binhai New Area's "863 CIGS thin film solar cells in the test base," made significant progress, the successful production of effective area of 804cm2 glass lining the end of CIGS solar modules, the photoelectric conversion efficiency of 7.00%. This achievement shows that China has basically mastered the manufacture of copper indium gallium selenide thin film solar cell manufacturing process and battery components manufacturers in the core technology, completed a small area of laboratory technology to large area solar cell technology by leaps and bounds in the trial for proprietary product line development has laid a good foundation.

Commerce Department: February 1 copper-nickel and aluminum recovery exemptions

Jan. 8 hearing the Ministry of Commerce recently announced that, in order to maintain steady growth of foreign trade, from next month on the 1st, the recovery of copper, nickel, cobalt ores and concentrates imported commodities such as tax exemption. At the same time recovery of refined copper, unwrought nickel alloys, non-alloy aluminum bars, rods and other goods exported duty-free policy. Analysis, according to dealers, which will increase China's copper, nickel exports and imports of primary aluminum.
