Turned to U.S. auto industry to shift production model
In China, Germany and Japan and other countries, paris on pure electric vehicles, plug-in hybrid electric vehicles, the U.S. auto industry to divert attention turned to the fuel cell vehicles , Mini 730 , announced in 2015 a number of businesses started in the production model of the United States.
A few years ago, the fuel cell vehicles on the auto industry by the technology sector of the United States and the general interest, even if they participated in tests on a small race car, but other types new energy vehicles compared to hydrogen fuel cell vehicle technology relatively mature, mainly the lack of supporting infrastructure.
Active construction of infrastructure
U.S. sales of Toyota’s director of advanced technology companies search announced that Toyota’s vehicles to fuel cell will be listed in 2015. It is understood that, in addition to Toyota, GM, DaimlerChrysler, Honda, Hyundai and many other car companies will fuel cell vehicles on the market in the U.S. is planned for 2015.
Car manufacturers are to achieve the goal of 5 years after the occupied. According to the National Hydrogen Association, U.S. existing hydrogen refueling station 68, the most in California. The lack of hydrogen stations become an obstacle to large-scale fuel cell vehicles to promote the main reason. Car manufacturers have recognized this and started to increase vehicle infrastructure to support fuel cell efforts. The companies hope that the car in 2015, 537626-001 , the hydrogen fueling station in the flower of the United States anywhere.
Automakers are still actively looking for sources of hydrogen fuel. This year, in May, GM signed with the hydrogen gas supply agreement, Hawaii, using parts of Oahu, United States, 1,000 km of pipeline transportation of hydrogen gas to hydrogen stations. GM expects the construction of Oahu, 20 25 hydrogen fueling station, hydrogen fueling station for each seat cost 300 000-50000000.
Desire to support policy
To promote fuel cell vehicles face challenges, but with less dependence on oil, and eliminate the two major advantages of pollutant emissions. In addition, the source of hydrogen over existing techniques, both the extraction, storage or transportation, not the problem. In addition, the European Union, for example, the organization in 2020, sales of new cars in Europe to reduce emissions of carbon dioxide by 20%. And compared to other types of new energy vehicles, zero emission, zero emission fuel cell vehicles to achieve this objective, the more advantage.
“In environmental terms, fuel cell vehicles and car battery lithium-ion battery is no different. However, recent government funding priorities shifted to lithium-ion batteries on board. But if Generally, even the most difficult period in the company has not abandoned R & D technology development of fuel cells continues to advance towards the goal. “GM Chief Executive of the World Fuel Cell Research Project said: “Now we lack is the policy of sustained support. ”
product performance Kennel
Hydrogen-cell cars, hydrogen fuel systems, including storage tanks, the fuel cell to power, energy storage of lithium-ion and the central nervous system of the control system of electric vehicles. Compared with pure electric vehicles, vehicles with fuel cell during a benefit, such as pure electric vehicles is fully charged, it is 7-8 hours, the hydrogen fuel cell vehicles hydrogenation time was only 3 , 5 minutes. In addition to the Honda FCX Clarity fuel cell, for example, the hydrogenation of a car driving range of approximately 386 km. GM will be in volume production by 2015, the same level of driving vehicles to fuel cell reaches 483 km mileage. In contrast, the same size electric cars on a single charge of driving range is only 160 kilometers.
Hydrogen vehicles with precious metals like platinum catalyst, the high cost was met through his business problems. Before 2007, manufacturing a fuel cell car is about 100 grams of platinum, common across the plane “entry” to substantially increase the efficient use of platinum catalysts to create a vehicle that has fallen into Use 30 grams of platinum. According to the plan for each GM vehicle in 2015, the use of platinum averaged 26 grams, try the next few years, more than 10 g or less.
According to Reinert introduced since 2005, Toyota has an average cost of fuel cell vehicles reduced by 90%. The next 5 years, Toyota will raise the technical level, so that the performance of fuel cells is more reliable, smaller and less expensive.ProBook 4510s , Try the case in the absence of subsidies, the average price of the vehicle control at 5 million dollars.
GM has announced that testing a new system of hydrogen fuel cells, the system program installed in 2015 with the car for mass production of fuel cells. And the Chevrolet Equinox fuel cell models compared to the next generation of cell volume decreased by 50%, weighing about 100 kg of platinum consumption decreased by one third, and the interior is more reasonable.
Hydrogen vehicles to eliminate barriers to commercialization, Reinert recommended that: “I hope governments and car companies to meet and overcome the difficulties”.
