Fuel cell breakthroughs to enhance the efficiency of filtration devices
In a variety of consumer electronics features Digital Camera Battery by leaps and bounds at the same time, the battery has been slow development of new battery technologies also seem very remote. Taiwan scientists have recently invented a new method greatly improves the efficiency of fuel cells, so that the future of this technology looks even more promise.
According to “New Scientist” magazine, National Tsing Hua University in Taiwan, a research team has developed a new filtering technology, you can clear out methanol fuel cell (DMFC) in some of the by-products, thereby enhancing its operational efficiency, while eliminating the need to spend extra energy.
As the catalytic reaction of methanol does not require DSLR Battery Grip complicated, dangerous to store than hydrogen easier, and therefore very suitable for DMFC for portable electronic devices provide energy, but due to the oxidation of fuel will produce carbon dioxide and other byproducts of power generation efficiency of methanol has been not very ideal.
Taiwan’s National Tsinghua University researchers have produced such a filter is expected to solve the problem. This passive filter is equipped with about 100 50-micron-sized holes can be carbon dioxide and other waste discharged into the atmosphere, but also covered by a layer of water-resistant Teflon (PTFE), can take away moisture at the same time does not affect the DMFC valuable energy output.
Samsung and Toshiba are all very interested in DMFC, but also launched a number of using this cell phone and other products.
Fuel cell E-Flex system, lead the trend of vehicle electrification Canon EOS 450D Battery Grip
In the 2007 Shanghai International Motor Show, the Chevrolet Volt electric concept car auto show has become the most compelling new energy concept car, called the current auto show “the most versatile of the Environmental Concept Car.” The reason is that for the first time this Chevrolet Volt concept car is equipped with General Motors so far the latest, most efficient hydrogen fuel cell system – E-Flex system.
In the April 19 meeting of the E-Flex press conference, General Motors R & D and strategic planning director, vice president of Wave Rieter said to reporters: “E-Flex system is a very flexible electric vehicle architecture, innovation is that you can let people in the same space to install a variety of propulsion systems, choose to install a propulsion system which can be decided according to local available energy resources. It also provided a great deal of energy flexibility – one can include wind , solar, geothermal, hydropower and other renewable resources and bio-fuels or a variety of conventional energy to get hydrogen or electricity, you can also directly on the external power supply charge for electricity, the perfect solution to the car energy Canon EOS 500D Battery Grip, global adaptability. ”
This time, GM’s global starting the fuel cell E-Flex system architecture can be no fuel, no emissions of power-driven travel 483 kilometers. Experimental results show that, equipped with a fuel cell E-Flex system, the Chevrolet Volt, whether size, performance, durability, or cost, have been able to par with the use of internal combustion engine vehicle. General Motors believes that energy shortages in today’s environment, it will eventually replace the internal combustion engine to lead the automotive industry into the age of electricity.
E-Flex System, but also greatly expand the new energy models in appearance, as well as interior design space. In the Shanghai Auto Show, the Chevrolet Volt will succeed in subverting the people “green car is not nice shape” and stereotypes. 21-inch wheels and succinct form lines passed directly to the characteristics of flexible and sophisticated, the external ratio is more like a classic sports car, gives a strong sense of fashion design. In the interior space, the wave Rieter that “the past, electric cars have many Canon EOS 1000D Battery Grip limitations, such as the passenger compartment and luggage compartment space is small, climbing ability is poor, can not be long-running air conditioners and so on, the Chevrolet Volt on these issues are to do a thorough improvement.
Battery rechargeable battery prices siege
Alkaline batteries last part of the price increases after the recent variety of brands of alkaline batteries again “rise in the price,” sounded. Reporter yesterday a number of small commodity wholesale market in the city learned that, due to rising cost of raw materials, South-fu, Deer brand alkaline batteries such as prices rose a troughs twelve months later. Rechargeable battery, therefore became a “darling.”
Yesterday, the reporter learned that a small commodities wholesale market, south-fu, Deer and other multi-brand alkaline batteries has increased in price. Original price of 3 yuan / Union 5 Deer battery has now been sold to 4 yuan / Alliance, and the original selling the 8 yuan for each of the 5 Nanfu battery, Nikon D40 Battery Grip and now get 10 yuan to buy down, which led many to buy batteries Customers are surprised. On the 1st miscellaneous stall owners told the reporter that the second half of last year, some cells began to change the price, but some industry operators are not due to the increased prices of goods and improve the retail price. However, the prices of goods there last year, the battery, “overstating”, in order to ensure profit margins had to push up the retail prices accordingly. Changes in the retail price of low-cost battery is not too great. Relatively high number of original price or the battery more obvious, the largest price increases more than the original price of five into.
The reporter learned from some of the stalls selling the battery learned disposable alkaline batteries prices, led many people have switched to buy a rechargeable battery. A battery sales stall holders said that sales this month than last month, charging the battery increases of at least two into. Because many consumers think, rechargeable batteries, although the price is slightly higher, but can be recycled, according to more than buying disposable batteries are quite Nikon D40X Battery Grip cost-effective.
