With the new fuel cell will use to take off

“With its features suited to the emergence of new uses, the application of fuel cells will become more and more widely.” September 12, 2004 to 14 in the United States, held in San Francisco on the portable devices of the International Conference on battery “Portable Power Conference and Expo”, the Toshiba Fuel Cell R & D person in charge said the voice of their own. The advantages of fuel cell unit weight of the energy density of current rechargeable battery 5 to 10 times, but it also has its weaknesses, show that the output power density of the instantaneous current output low. To solve this problem, many people on their portable devices as the main power supply is not overloaded and have had a doubt. In response, Toshiba Corporation is responsible for direct methanol fuel cell (DMFC) development of parts of the display material mains, Fumio Ueno, chief engineer on the popularity of their views on fuel cells.
In his speech he said that Toshiba is stepping up its development of three kinds of portable devices for fuel cells, which are for notebook computers increased power density of the active DMFC, such as pocket-sized mobile phone charger for small active DMFC, surface to portable music players and other devices of the passive DMFC.
Do not add pumps which can be added to the fuel cell unit of the passive methanol fuel cell output power density is expected to be low. This passive type fuel cell is not applicable to GSM mobile phone seems like the need for high-power current pulse-based equipment. But more suitable for high current does not need to work on the portable music player and so on. “In the low current, but users are troublesome charge, in the face of such equipment, with high energy density fuel cells have been useless. Fuel cell energy density than the lithium-ion rechargeable battery. This will significantly eliminate the user from time to time to worry about the shortage of battery capacity. ”
The low power density fuel cells, should be excavated in accordance with its characteristics corresponding purposes. “For example, intact in order to replace the current mobile phones use lithium-ion rechargeable battery may be very difficult. On the contrary, should the equipment is not yet available, the use has not yet appeared when to use fuel cell” (Fumio Ueno). As lithium-ion rechargeable battery with the camera body of a VTR (video camera) the appearance of the equipment and the expansion of the application, like the advent of the new equipment will greatly promote the application of fuel cells.
Referring to the new use, the Bluetooth headset the most cause for concern. “Bluetooth support for headset power consumption is very small, There is nothing to the headset and charging users a more troublesome matter. If the passive-type fuel cell mounted on the headset, it can be used for a long time. A reduction of the replacement battery or charger trouble “(Fumio Ueno). The current use of headphones into the rechargeable battery unit weight energy density of the fuel cell 1000Wh/kg, then probably use the time to achieve the current 3 to 5 times. In fact Finland’s Nokia is equipped with fuel-cell prototype of the Bluetooth headset. With the advent of fuel cells, which in turn promoted the low-power, want to ensure that prolonged use of equipment.
Fumio Ueno In his speech after the end of the common with other speakers participated in the panel discussion. Actively promote the development of fuel cells for portable devices Toshiba has become the focus of attention will also field questions focused on who Ueno. Ueno by answering a question by depicting the future of rechargeable batteries: “Looking back, nickel-cadmium, nickel hydrogen, lithium-ion battery, such as various types have come out in succession. But without a battery will completely disappear. Each cell are most suitable for it areas continue to be used. In view of this, even if the fuel cell on the stage, lithium-ion will not disappear, will continue to use different application “, meaning that the proper and best use is the most realistic idea.
Professor Yu Zhuoping Shanghai fuel cell vehicles on the industrialization of the idea
September 16,’2004 Shanghai to exchange the development of fuel cell vehicles will be ‘held. The meeting next year, Shanghai will be the realization of fuel cell vehicles more than 10 small-volume production vehicles, the first hydrogen refueling station will be built at the same time.
At the meeting, our school, executive vice president of Automotive Institute Professor Yu Zhuoping Shanghai fuel cells made of the idea of the automobile industry. In accordance with national long-term development plan, by 2020, cars in China increased by 5 times than now, reaching 100,000,000 3 10,000,000, while traffic to the growth of oil consumption control in less than 2 times. To achieve this’5: 2 ‘type of non-balanced growth, the only way to speed up energy-saving and clean energy industries of the pace car. 2006 to 2007, Shanghai will have 100-class production capacity to form the model team, the construction of several hydrogen refueling station; in 2008 by the year 2010, will have production capacity of 1000-level, the composition of commercial fleet operators, the construction of several Hydrogenation of 10 points; in 2011 to 2015, will have production capacity of 10,000 level, the achievement of regional business, and the construction of hydrogen refueling station 100. If all goes well, by 2020, fuel cell vehicles with traditional internal combustion engine will have the same competitive car and become the mainstream car market.
Fuel cell vehicles using hydrogen as energy source, non-polluting, low-power, low noise. Since 2000 the city was listed as a major scientific and technological project, its research and development process of concern, the concept car ‘than those on the 1st’, ‘beyond those II’ has been published. It’s the third generation – ‘beyond the Route’ will be the driving force for the platform to receive the acceptance of science and technology. Compared to the previous two generations, and once again ‘downsizing’ of the ‘beyond Route’ to achieve the key components of the modular design not only greatly improved reliability, there are also in the energy-saving performance for the bulk of production to lay the foundation. Next year, with the ‘go beyond the 3rd’ out like cars, fuel cell vehicles in Shanghai technical reserves will also be stage ends.
