Positive R & D work in Japan more than 10 hours of fuel cell

The United States message, laptop for at least 10 hours continuous power fuel powerbook g3 battery,HP laptop battery powerbook g4 battery cells to make computer fans looking forward to it, but supporters need to prove the safety of such batteries.

Although experts say the limited battery life will continue to exist for several years, but Japanese companies are actively research and development of micro methanol fuel cell power generation prototype.

Toshiba and NEC have developed a fuel cell power generation prototype of the laptop, Pavilion XZ200, Pavilion ZT1100, Omnibook XT1000, Omnibook XT1500
and plans to launch an official product. In addition, research and development at the micro fuel cell technology also Casio, Sony, Hitachi and Samsung.

Components of fuel cell manufacturers, fuel cells Entegris president Goodman (John Goodman) prediction, a few years, similar in size and lighter, or even a smaller fuel cell will be able to supply at least 10 hours a day - p

Chip maker Intel in February demonstrated a prototype fuel cell power supply from the laptop,Omnibook XT1500 and battery manufacturers are Intel invests in PolyFuel.

Normative obstacles to be overcome

Market research firm Allied Business Intelligence Research on the person in charge of energy Utterback Oz (Atakan Ozbek) said that the current laptop battery generally can continue to use 3-5 hours, and fuel cells are the initial target of 6-8 hours, will eventually reached 12 hours a day.

Oz Toback said the initial price of fuel cells is expected to be about 200 U.S. dollars, while most traditional notebook for the price of 120-180 dollars. He also said that the micro fuel cell to replace conventional batteries in full prior to the initial stage will be the form of battery backup.

Related companies are being developed into small enough to laptop and play in extreme climate of the good performance of the fuel cell. The experts have said that although these companies are to overcome the technical obstacles, but obstacles still exist norms.

Allied Business Intelligence predicted that in 2004 with "micro" fuel cell laptop in shipments worldwide in 2000 will be only negligible Units.

It also predicted that four years later,Omnibook XT1000, this figure may increase to 100 million units for the benefit of up to 150 million U.S. dollars.Pavilion XZ200, Pavilion ZT1100, Omnibook XT1000, Omnibook XT1500
By 2011, the fuel-cell laptop battery: battery, apple m8244g battery shipments will reach 120 million units, compared with 1.2 billion U.S. dollars revenue.

And the United States large laptop manufacturer is to keep watching this.

Temperature solid our country towards the practical use of fuel cells

Intermediate temperature solid oxide fuel cells with oxygen ion conductive thin films for solid oxide electrolyte membrane, the temperature at 650 ~ 800 ℃. Due to the electrode catalyst without precious metals, manufacturing, low cost, with good prospects for the industry. Cheng Mo-Jie told reporters that in the intermediate temperature solid oxide fuel cell can be described as a "coarse to eat, do event." The so-called "coarse grains to eat," because it does not rely on expensive hydrogen, whether it is natural gas, town gas, liquefied gas or biomass gasification, can be used for its fuel, the use of air as oxidant, could be the chemical energy of fuel oxidation efficiently into electricity. The so-called "big do" is because of intermediate temperature solid oxide fuel cell rich source of fuel, no noise, NOx and SOx emissions very low, and its high power generation efficiency, up to 60% ~ 70% of the Cogeneration is clean, Pavilion ZT1100,efficient power plant technologies, but also be considered changes of the future power plant technology can be applied to large-scale power plants, distributed power plants, home station, vehicle auxiliary power supply and so on, on the national economy and society have a major impact on sustainable development. At present, internationally renowned companies such as Siemens - Westinghouse, GE and other companies invest huge sums of money in this regard to carry out research and development. In addition, the intermediate temperature solid oxide fuel cell can be miniaturized, and micro-electro-mechanical systems technology, has developed a possible all-weather portable apple m8403 battery, apple m8433g battery.

Researchers after nearly two years of efforts have been successful in high-performance temperature solid oxide fuel cell membrane electrode, metal bipolar plate, the high temperature sealing materials, such as key components of battery technology. They are developed in particular temperature solid oxide fuel cell bipolar plate abandoned ceramic materials, the use of easy to get the stainless steel bipolar plate cost is low.

The group also developed a direct gas-solid oxide fuel cell materials, the single-cell work at 750 ℃, the maximum output power reaches 2000mW/cm2. At present, the host temperature solid oxide fuel cell research has been applied for Chinese patent 8. In addition,Pavilion XZ200, the group is currently also working with China National Petroleum Corporation to conduct electrical energy generation and chemical products of the project development .
