Solid oxide fuel cell

Solid oxide fuel cell

Recently, Professor Barnett at Northwestern University developed a new solid oxide fuel cell. The laptop battery for the use of iso-octane fuel energy conversion efficiency is expected to reach 50%. Usually energy conversion efficiency of internal combustion engines does not exceed 15%, the existing hydrogen fuel cell efficiency is 29%, the latest hybrid vehicles efficiency of 32 percent, however, the advent of the cell effectively improving the energy conversion toshiba battery rate.

Professor Barnett, the existing disadvantages of hydrogen fuel cells is that the need for a large number of new hydrogen purification plant will extract hydrocarbons from the hydrogen, if hydrogen fuel cell vehicles needs to be applied to many new "hydrogen refueling station . " Hydrogen purification, transport and storage are in need of special technology, the application has greatly increased the cost. On the contrary, the use of iso-octane new solid oxide fuel cell, which is equivalent to the hydrogen purification plants, "compressed" in a small device, and iso-octane are straight-chain hydrocarbons, and gasoline are very similar, no new infrastructure, so the prospect of fuel cells.

The new fuel cell, after more testing, can be widely used in automobiles, aircraft, and even many families.

China's pressure proton exchange membrane fuel cell research was a breakthrough

Recently, the Chinese Academy of Sciences core component in the fuel cell membrane electrode study of three-in-one manufacturing technology to make new breakthroughs.

To address the high-pressure fuel engine running on air compressor power consumption due to large, difficult and complex control systems, pressure decided to develop proton exchange membrane fuel cell engine.

After more than three months of research, the project technical performance of the same company with the United States Al Gore, a single cell maximum power density of 0.52W/CM2, working in 700MA/CM2 voltage of 0.64V, reached the international advanced level. Three-in-one membrane electrode manufacturing technology breakthrough innovations will further enhance China's overall level of fuel cells.

New type of photovoltaic cells made a significant breakthrough

Photoelectron from the toshiba satellite l25 battery, toshiba satellite prol10 battery Nankai University Geng Xinhua, Zhao Ying group of countries to assume ""---" 973 low-cost projects, long-life photovoltaic cells based on new research" project has international and national standards through testing, approved for 20 (film ) 400 square meters of amorphous silicon cell efficiency of more than 8 percent, the maximum efficiency of 9.1% reached the international advanced level of similar cells, the highest in the country.

Pure battery buses bulk carriers in Beijing

Beijing Science and Technology Commission, said recently. Beijing the first batch of 34 pure battery buses: array in operation, the 34 electric buses in Beijing were produced, with a length of 8m ~ 10m, the maximum speed of up to 80km / h, continued driving mileage 1 50km ~ 200km . Although the cost of electric buses than regular buses, but bus fares as currently, there is no plan to raise prices.

It is reported that the forthcoming operation of electric buses to battery-powered, low power use of night-time charge, no emissions, no noise, are completely non-polluting bus type. Beijing Science and Technology Commission, the person also said that by 2008, Beijing will reach thousands of electric vehicles bus.

EBL cell phone technology more longevity at lower power consumption make LCD

Intel has always been all mobile computers in order to continue to make R & D batteries, the battery can look forward to working more than 10 hours, of which there is a low-power LCD products EBL, is near completion and will pitch in the IDF show Intel the LG-Philips used its EBL technology, the power consumption of the LCD Panel only 2.47W, than the average LCD to 8W less about three-quarters, and in 2005 is expected to be the first quarter volume of 4 products on the market, toshiba satellite prol20 battery, toshiba tecra l2 battery life for mobile computers into a major step-by-step.
