According to reports from the Japan Economic News, 11 major automakers, including Japan's Toyota, Germany's Daimler, and U.S. General Motors, are about to unify the seeds of next-generation eco-cars, the hydrogen supply system specifications for fuel cell vehicles.
At present, the automakers have basically agreed to harmonize the specifications of the connector that injects hydrogen gas into the car body from the storage tank. In 2012, it will also complete the qualification of the International Organization for Standardization. Correspondingly, in the field of electric vehicles, there is a slight delay in the unification of the international standards for connecting chargers and body cord plugs. In the field of fuel cell vehicles, all manufacturers will agree on the issue of unification of specifications, which will greatly promote the adoption of fuel cell vehicles.
It is estimated that fuel cell vehicles will enter the practical stage after 2015. In order to refuel the car, a hydrogen station like a gas station is indispensable. However, if the connector specifications are not uniform, mass production of vehicle bodies and supply systems will be more difficult and costs will remain high, and the popularization of fuel cell vehicles will be much more difficult.
In addition to Toyota, Daimler, and GM, the auto makers participating in this specification are also Nissan, Honda, Suzuki, Renault of France, Volkswagen of Germany, BMW, Ford of the United States, and Hyundai of South Korea. The major manufacturers of battery vehicle development plans have joined the unified plan for this specification. At present, various manufacturers are also working toward the goal of unifying specifications in response to pressure conditions in storage tanks.
In the field of electric vehicles, because the international specifications of the wire plugs connecting the charger and the vehicle body are not unified, each automobile manufacturer and energy company has to take corresponding measures according to the different regions. This is an important reason why the popularity of electric vehicles is very slow. It may be that lessons have been drawn from the slow adoption of electric vehicles. From the earliest stages, manufacturers have begun to cooperate toward the goal of unified specification. With the basic determination of unified specifications, all manufacturers have also accelerated the development of research and development in order to promote the practical use of fuel cell vehicles as soon as possible.
From 2012, Daimler will cooperate with Linde Group, the world's largest industrial gas supplier, and add 20 hydrogen stations to the center of the city. Daimler also conducted technical cooperation with Renault-Nissan and plans to launch fuel cell vehicles in the Japanese market around 2015. Thirteen companies, including Toyota and Japan's largest refiner, JX Nippon Mining and Japan Energy, will start construction of hydrogen stations in 2013. With the Ministry of Economy, Trade and Industry of Japan, and other relevant departments to relax the relevant safety specifications for hydrogen tanks, in 2015, these 13 companies will increase hydrogen stations to more than six times today, reaching 100 sites.
The fuel cell car uses the principle that is completely opposite to the electrolysis, and the electricity generated by the chemical reaction of hydrogen and oxygen in the air drives the engine to run, thereby driving the car. Unlike electric vehicles, which use stored electricity to drive the car, the fuel cell car runs while generating electricity. It discharges only water during driving, and does not produce harmful gases that pollute the air. Hydrogen's energy density is 10 times that of a vehicle-mounted lithium-ion battery. Hydrogen can travel longer distances. In addition, electric vehicles need to be charged for a long time, and fuel cell vehicles can be refueled in a short time.
To sum up, fuel cell vehicles can be said to be "the most environmentally friendly car" in terms of environmental performance and convenience.
