NEC notebook fuel cell power density
First post by: www.batterystores.ca
With the “WPC EXPO 2003″ on the Toshiba Tecra 8000 Battery display using the fuel cell of the workshop held at the same time, “the fuel cell is about to infiltrate into portable devices” (September 17, day after day by the electronics and environmental protection jointly hold) on, NEC to do the relevant technical Speech, and declared at the non-use of auxiliary machine-type “passive (passive)-type” direct methanol fuel fru 92p1167 battery, thinkpad z60t battery (DMFC) in the world achieve the highest output power density that is 50mW/cm2. Here, passive (passive) type is the catalyst by improving the electrode and electrolyte film unit, thereby enhancing the output power density without the use of pump and fan (Blower) and other auxiliary machines to high-density power output of the fuel cell. The company intends to further improve the materials in order to achieve practical implementation 100mW/cm2.
NEC has been able to successfully improve the output power density, based on Toshiba Laptop Battery its load at platinum catalyst particles Tam material used is called “carbon nano-process (Carbon Nanohorn)” nanotechnology of carbon materials manufacturing. Process because of the carbon nano-micro-nano-class structure, and therefore can make the following micro-5nm platinum micro-particles can be dispersed, which would increase the catalyst surface area and thus improve the output power density. In addition DMFC in order to solve one of the topics Crossover (because of methanol through the electrolyte in order to cause the problem of declining output power), which is difficult through the use of methanol the solid electrolyte membrane, in June 2003 issued by the same type of fuel cell output power density of 40mW/cm2, the reason can be reduced to 10mW / cm2, is because “by raising the electrolyte membrane and the adhesion between the catalyst, thereby reducing the resistance, and the efforts ibm laptop battery, thinkpad z61t battery carried out because of the crystallization of solid “(NEC foundation Applied Research Institute of CNT Center Research Minister Okubo long is good). The Laptop Battery current Department of Materials has reached the limit, in order to achieve higher 100mW/cm2 is a catalyst for research activity.
Passive (passive) type fuel cell are by infiltration and proliferation of methanol, natural inhalation and air transportation, fuel cells, because of its small size, light weight and noise characteristics, so that the NEC for portable devices are the best technology . But the display’s built-fuel cell type, are at the bottom of the laptop to install the fuel cell group, in order to supply fuel and replacement of the air using a small pump and fan. In this sense, no longer belong to the passive (passive) products, but the company has explained that the use of these auxiliary machine is designed to solve the layout of the fuel cell problem, nothing to do with the output power. The company said it would replace the current fuel cells in February 2003 issued by an external vertical type, the use of gravity or the supply of fuel is designed to easily inhaled air can naturally achieve the same output power density. The company intends to continue to take the “passive (passive) Type” to improve the output Toshiba Tecra 8000 Battery power density battery.
Honda at the 36th Tokyo Motor Show on display is planned for the end of 2002 in Japan and the United States to limit sales of the two fuel fru 92p1141 battery, fru 92p1137 battery cell vehicle “FCX”. FCX issued by the company’s fuel cell test vehicle “FCX-V4″ to improve from. Prototype vehicle FCX-V4 and the main difference is that the body length than the FCX-V4 shortened 40mm, equipped with fuel cell power generation display status and capacitor charge-discharge status can be traveling distance, speed of the three instrument panel, driving distance to improve 315 ~ 355km, a top speed from 140km / h to a 150km / h.
Fuel cells, capacitors, fuel cans and other major components with the basic layout has not changed. The company has with the United States Los Angeles, five on the video “FCX” reached a basic agreement. However, in the form of rental, the cost of such details not yet been determined. First of all, in Japan plans to limit sales and rental in the Seoul metropolitan area, but has yet to identify specific and rental costs.
FCX’s main components for the electrical, fuel cells, capacitors, fuel cans. AC synchronous electric motor for maximum output power of 60kW, the maximum torque to 272Nm. The provision of electricity to the motor are fuel 02K6651 battery, 02K6620 battery cells and super capacitors. Canadian Toshiba Tecra 8100 Battery fuel cell using Ballard Power Systems produced solid polymer electrolyte fuel cell (PEFC), an output power of 78kW. 35MPa fuel use of compressed hydrogen. Hydrogen storage tank capacity of 156.6L, over 137L of the FCX-V4 has been greatly improved. The purpose is equipped with super-capacitors are Recycling deceleration energy and speed up when used as electrical power.
Overall dimensions for the 4165 × 1760 × 1645mm, weight 1680kg. Top speed of 150km / h. Driver output power and micro-cars and smaller engines of the same level, torque level for the 2 ~ 3L. Because of motor status at the next stop could achieve N.m, so start about 5 seconds after the acceleration in good condition. Since then the acceleration due to body weight than the number of gasoline, so less than petrol vehicles. FCX positioned level city car, with the level of the gasoline car to light 02K7039 battery, thinkpad x60 battery 1200 ~ 1300kg.
In view of micro-electromechanical systems (MEMS) is expected to become a foundation to support the new technology industries, Japan is accelerating the development of all walks of life. Experts predict that the future fuel thinkpad a20 battery, thinkpad a20m battery cells and gas turbines probably only two centimeters in diameter, probably have a chip on a chemical plant.
“Japanese Economic News reports”, MEMS technology has been applied to vehicles used to Toshiba Tecra 9000 Battery accelerate the airbag sensor, deoxyribonucleic acid (DNA) chips, is expected to apply in future sensors, optical communication, energy, biological and chemical aspects .
Northeastern University Professor Jiang-xi, such as barbed people are using semiconductor manufacturing technology, try to create a diameter of about 2 centimeters of ultra-small gas turbines and fuel cells, this gas turbine suitable for driving robot and electric wheelchairs, small fuel cells can serve as mobile phone and notebook computer thinkpad a21m battery, thinkpad r60 battery power.
TOSOH Corporation developed “micro-chemical plant” can be used in liquid crystal display components, medical and so on.
Think the Japanese government is expected to lead a new generation of MEMS technology industry, it was decided to assist in the development of this technology. Economy, Trade and Industry from the next year to develop MEMS design and analysis used to support the technology, to develop a standard system for the manufacture of electronic and mechanical components of new enterprises and SMEs can benefit.
This set of design and analysis systems are manufactured atToshiba Tecra 9100 Battery ultra-small machines before the computer simulation experiment to determine the performance. ibm laptop battery, 40y6797 battery
Because of volume reduction to very small, the thermal conduction mode and the friction will be different, pre-analytic and assessment of essential, but new enterprises lack of experience necessary to have a standard system. Economy, Trade and Industry’s Institute of Advanced Industrial Science and Technology plans to provide basic information, Olympus Optical Co., OMRON will also provide assistance to such companies. Government investment in the next three years book ¥ 1,500,000,000.
MEMS technology in the current global market size of about 5,000 billion yen, the United States, Japan and Europe the same technology. The global market in 2010 is estimated to grow to 2 trillion Toshiba Satellite 1900 Battery yen.
