Progress in engineering cells
Tin Kona United States (Ticona) in the K2004 NP-20 exhibition demonstrated a cost-effective fuel cell vehicle modules laptop battery, called PEM fuel cells using the company's brand Vectra liquid crystal polymer (LCP) and Fortron brand acer battery Polyphenylene Sulfide (PPS) engineering plastics are made. Introduction LyndonCole president said in the fuel cell bipolar plate by 85% of graphite and 15% of the liquid crystal polymers, the end of the parallel-plate made of the use of PPS.
Tin Kona with a new company set up by German companies Pemeas cooperation, the use of its polystyrene benzyl imidazole (PBI) membrane materials that can be 120 ~ 220 ℃ in the work of the fuel cell. As the first practical fuel cell was designed 40 years ago, used in practice has proved the most viable PEM fuel cell membrane material is the launch of DuPont Teflon (Teflon), which is used in the polymerization coating materials. Fluoride membrane in conditions of high humidity can be stable, while the PBI membrane humidifier without any process, it eliminates the need of complex water treatment processes. PBI membrane in the use of hydrogen gas into the environment more resistant to carbon dioxide pollution, the resulting gas purification VGP-BPS9 B , VGP-BPS9 S process can be more simple and therefore the possibility of the use of PBI divide divide more economical than the fluoride reliable.
South passed the development of new standard test battery
Yesterday was informed that the opto-electronics, Nankai University borne by the State "973" project --- "low-cost, long-life photovoltaic cells based on new research" has been the subject of international and national standards for testing, approved for 20 (film) 400 square centimeters of non - the efficiency of VGP-BPS2A , VGP-BPS10 crystalline silicon cells are more than 8%, the highest efficiency reached 9.1%, to reach the international advanced level of similar cells, the highest in the country.
Noritake direct methanol fuel cell performance of the highest in the world
10 Noritake Japan announced that is developing in the "organic-inorganic hybrid electrolyte membrane" of the direct methanol fuel cell (DMFC) performance to reach the highest level in the world. Relevant details will be October 8 ~ 13, which opened in Yokohama, Japan "International Federation of Materials Research," published.
Up to now, Noritake has been engaged in the direct use of liquid methanol fuel in DMFC electrolyte membrane development, rather than gas reforming device. DMFC with the fuel due to no modification, and can work at low temperatures, etc., is easy to implement small-scale design, portable power supply Sony vgp bps2c , VGP-BPS8 in the area of popular concern about the development.
Methanol and oxygen in the practical state closer to the supply of non-pressurized conditions, Noritake 160mW/cm2 the products have been the high power density, performance is about 1.5 times the original. Is able to achieve such a high performance, according to the company's analysis, the main reason lies in the use of organic and inorganic hybrid electrolyte materials production technology, greatly reducing the methanol through the electrolyte membrane of the "infiltration of methanol (Methanol Cross-over)" phenomenon, and to improve the shape of the electrolyte membrane stability. Moreover, it is said above, even in mixed electrolyte membrane 1000 hours after the endurance test will not be aging.
On the use of such organic-inorganic hybrid electrolyte membrane fuel cells, while Wu's goal is to put into use in 2005. Preliminary plan for electric tricycle, electric wheelchair, camping grounds and motor vehicles, such as market power. Put into use at the time of annual sales target Sony VGP-BPS9 Battery , vgp bps2c of ¥ 100,000,000 (about 6.25 million yuan).
Speed up the promotion of fuel cells on the btp-aqj1 battery, btp-arj1 battery, acer aspire5540 battery development of energy-saving "out of oil" strategy
According to the Japanese NHK television reported, in view of rising crude oil prices, the Japanese government held a meeting on the 15th to discuss the development of "out of oil" strategy.
Japanese Prime Minister Junichiro Koizumi at the meeting directed the departments to develop "out of oil," a new long-term strategy, through the use of new technologies such as fuel cells to reduce dependence on oil. It is reported that Japan intends to formulate a new strategy including the promotion of the introduction of fuel cell and other new energy technologies, and further speed up the business, family and other energy-saving steps. In 2030 the Japanese government intends to bring "oil dependence", that is, the total energy Sony VGP-BPS8 Battery consumption of oil increased from about 50% now down to 40%.
Taiwan investment in TEDA Microelectronics great battery cell
Great battery from Taiwan Microelectronics Industrial Park in Tianjin Development Zone of Tianjin invested Chase Smart Battery Development Co., Ltd. held the foundation laying ceremony of a few days ago. The company focuses on production and operation of high-performance sealed VRLA batteries, such as high-tech products.
It is understood that a total of Tianjin plans to Chase microelectronics industrial land 42,000 square meters, the first phase of 20,000 square meters of land, five million U.S. dollars investment, 100 million yuan annual output value is expected.
Nankai University, "973" project the efficiency of photovoltaic cells new nation's first
Photoelectron by Nankai University Geng Xinhua, Zhao Ying national team commitments Sony vgp bps2c battery , sony battery VGP-BPS2A, "973" project - "low-cost, long-life photovoltaic cells based on new research" has been the subject of international and national standards for testing, approved for 20 (film) 400cm2 amorphous silicon cell efficiency of more than 8 percent, the highest efficiency reached 9.1%, to reach the international advanced level of similar cells, the highest in the country.
In view of the existence of amorphous silicon cells with lower acer aspire5550 battery efficiency, poor stability, higher costs, thus affecting the promotion of the application of large-scale problems, group members focused on thin film silicon photovoltaic cells to improve the efficiency and repeatability, to improve stability and life, the development of practical, low-cost manufacturing technology for the industrialization of service efforts and made significant progress and breakthroughs. Development of the aging of the battery through the international standard IEC1646 (85 ℃ temperature and 85% humidity for 2000 hours, -40 ℃ 40 hours) testing, battery performance has not degraded, and some have even been improved.
The research team not only developed a highly efficient battery, but also developed a combination of the three current international high-speed low-cost deposition technologies, world-class performance of radiation-based multi-purpose high vacuum thin film deposition systems, and automated preparation of highly VGP-BPS9, Sony VGP-BPS8 efficient microcrystalline silicon cells and amorphous silicon / microcrystalline silicon tandem cell process automation software, and applied for a patent. VHF-PECVD system uses high-speed preparation of cell deposition, small area of high-quality amorphous silicon deposition rate of more than 50A / s. Device-level access to the quality of the new characterization of microcrystalline silicon materials and process parameters and their relations based on the conditions, 0.253cm2 single-junction pin type microcrystalline silicon cell efficiency of 8.3%, amorphous silicon / microcrystalline silicon tandem cell efficiency of 10.2% 100cm2 integrated amorphous silicon / microcrystalline silicon tandem cell efficiency of 9.7%, are up to international advanced level.
At the same time relying on thin film silicon photovoltaic cells Nankai University and Tianjin technology to companies such as investment cooperation, "Tianjin Battery Technology Co., Ltd. to" set up to begin the process of the battery industry, jointly set up battery production line 5MW Amorphous and formally put into operation a good prospect. 6MW two flexible assembly line production of amorphous silicon cells are the building of three 30MW amorphous silicon cell production line has begun demonstration sony vgp bps9 , VGP-AC19V13 , Sony VGP-BPS2A projects.
