Bright prospects for hydrogen-cell vehicles

Bright prospects for hydrogen-cell vehicles



"Very quiet, definitely not the traditional internal combustion engine can do laptop battery. Accelerate quickly, have been driving electric golf carts would have similar feelings." MSNBC reporter meters of the (MiguelLlanos) trying to drive one Honda FCX hydrogen cell vehicles, the true description of my feelings.



Really driving the hydrogen cell vehicles have been a handful of people dell battery, for many people, this new car is also overshadowed by the energy of color magic. M the said, and his expected different, Honda did not detail his training. "Drivers and simple steps, and the general is no different from the car."



Then driving a car from Los Angeles to San Diego FCX. There are 160 kilometers along the way, his car almost before the arrival of the activities of the energy station on the run out of fuel. But also in the uphill time because the power is insufficient, resulting in a minor traffic jam. But he was proud of the fact that two of the drivers passing through on his marked "hydrogen battery-powered" in the car the thumbs up. From the beginning of the first hydrogen energy station



ChevronTexaco Technology Investment Limited ( "CTTV") this year on February 18 showing its construction in the United States, California's first hydrogen energy station. Hydrogen Energy Station is located in the California agricultural Kai (Chino) Industrial Park in the city, is the U.S. Department of Energy "to control the development of hydrogen energy, hydrogen energy technology to display and validate" part of the project, which is scheduled for 5 years, funded by the U.S. Department of Energy and assessments of the energy companies, CTTV joint force is to take the lead in this company, Hyundai Motor Company and UTC battery energy companies have also participated. These companies hope to gain from this project technologies and experiences in order to facilitate future development.



4 months, our reporter went to here, and follow-up interview with a market research expert CTTV Dona Miss Liu (DonnaS.Lau).



The energy station is small, is a only, surrounded by an open architecture, very modern design. The most eye-catching sleek device is automatically hydrogenation four machines, but only two can be used to add hydrogen. Different from ordinary gas station, the air is not filled with petrol smell the ground, not greasy, very clean. "No Fireworks" signs on the prescribed places.



For car users now, most of them seem familiar with the equipment. Miss Liu conversation with reporters that the energy station can give 3-5 hydrogenation hydrogen cell car demonstration, fill a car every time about 3-5 minutes. At present, the energy station can not be made available to the public use, a number of modern production of second-generation hydrogen cell car demonstration of this energy station is the only customer.



Natural gas is the energy source of the energy station. CTTV automatic use of heat re-engineering the company's patented technology, the energy station to hydrocarbon is converted to hydrogen. After compression, filtering, re-compression and storage, hydrogen cell vehicles lost. The energy station from ethanol (alcohol) in the production of hydrogen. In future, the energy station will also be displaying produce hydrogen through water electrolysis technology.



At present, the energy station can be stored in cabinets in the compression of about 100 kilograms of hydrogen, enough for five hydrogen cell vehicles to fill hydrogen. In addition to the battery as the importation of hydrogen, hydrogen can be used as the internal combustion engine has been modified to use the energy directly.



The future, CTTV elsewhere in California, Oakland and other places such as the y9943 battery, dell inspiron 630m battery establishment of five hydrogen energy stations. Hydrogen Energy: The "water" to replace oil



Hydrogen is a clean, abundant energy reserves. Water, natural gas and some organic compounds in the hydrogen can be extracted. Hydrogen is what we know about energy / weight ratio of the maximum effective energy. To produce one kilogram of hydrogen is equivalent to 1 gallon (about 3.78 liters) of energy emitted by gasoline. Today, the United States industrial production of hydrogen can be produced by the supply of 20 million ~ 30 million cars, or five million to eight million users.



As a vehicle of energy, hydrogen has a very significant advantages: it produces water vapor after combustion can be used as safe as gasoline and can be from a variety of other resources extracted in various ways. Extraction methods currently used in high temperature decomposition of natural gas, or water electrolysis. Hydrogen car has not been the advent of the era



As early as 2000, several studies of hydrogen cell vehicles of large companies such as Daimler, (DaimlerChrysler) and BMW think they will be able to start mass production in 2004 of hydrogen cell vehicles. However, due to inadequate infrastructure, lack of hydrogen energy station, currently the main types of environmentally friendly cars or two cars petrol power, hydrogen cell vehicles in the United States, the figure only a few roads.



U.S. National Hydrogen Energy Association (NationalHydrogenAssociation) Technical Director of PatrickSerfass said, "hydrogen cell vehicles are very optimistic about the prospects, but we are still in the research and experimental stage."



According to MSNBC reports, many motor vehicle dealers are not in the next 10 years of hydrogen cell vehicles to the mass market.



According to a Los Angeles company of hydrogen cell vehicles (HydrogenCarCompany) Sales Director of the Buddha Agathocleous Lietz (LloysFrates) the information provided within a year they only sold the high cost of two hydrogen cell vehicles. The current reference price is a battery-powered hydrogen ShelbyCobras price 150,000 U.S. dollars; only the Hummer jeep converted into a hydrogen battery-powered, it is necessary to cost 60,000 U.S. dollars (except the price of the jeep itself). The high cost of the hydrogen cell, hydrogen fuel and energy costs have affected the popularity of stations to the spread of the hydrogen cell vehicles.



In addition, cost-effective hydrogen-cell vehicles and the burning of gasoline is far from the car mentioned in the same breath. California manufacturers (Anuvu) claimed that they can immediately sell Nissan Frontier truck (Pick-up), but this car as soon as more than 45 miles per hour (about 72 kilometers), the hydrogen battery for power supply can not keep up with consumption , we can only open on the highway for short periods of time.



Sales Director House predicted that if the can produce 100,000 battery-powered home hydrogen truck dell inspiron 640m battery(pickup), the price of each vehicle can be reduced to from 20,000 to 25,000 U.S. dollars or so. Tin Kona United States (Ticona) in the K2004 exhibition demonstrated a cost-effective fuel cell vehicle modules, called PEM fuel cells using the company's brand Vectra liquid crystal polymer (LCP) and Fortron brand 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 process can be more simple and therefore the possibility of the use of PBI divide divide more economical than the fluoride reliable.

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 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 of ¥ 100,000,000 (about 6.25 million yuan).
