Hydrogen fuel cell cars are very hot recently. On November 18, Toyota officially released its mirai, a production hydrogen fuel cell car in Japan, and is going to be listed in Japan. In mid-November, Honda also released its latest hydrogen fuel cell fcv sedan Said it will be listed in March next year; At the same time, Volkswagen Group show no sign of impunity, at the Los Angeles Auto Show, including its Audi a7 sportback h-tron quattro, including three hydrogen fuel cell vehicles. Car companies are so intensive action, is passing a clear signal: hydrogen fuel cell car is no longer a "future legend", but the upcoming market-oriented new generation of green automotive technology. As a term that makes us feel a little strange, what is a "hydrogen fuel cell vehicle"? How does it work? Compared with other types of vehicles such as pure electric vehicles, its advantages in the end where? This article will be for you one by one interpretation. Hydrogen fuel cell car what kind of car? At present, hybrid vehicles and pure electric vehicles are gradually being accepted in the market, becoming a major change in the form of automobiles after ordinary diesel locomotives. Hybrid vehicles rely on a combination of fuel-powered and motor-powered vehicles that provide the vehicle's driving force. In general, hybrid electric vehicles are powered by pure electric motors at low speeds such as starting off, and are driven by the dual power of a diesel engine and an electric motor under conditions of rapid acceleration to achieve the effect of increasing fuel economy. (Such as Toyota Prius, Volkswagen Golf gte, Ford Mondeo mixed version are all typical hybrids) There is also a class of extended range hybrids, which are also equipped with a fuel dispenser and a motor. However, the vehicle itself is driven by a motor. Usually, the task of the fuel engine is to charge the vehicle battery. Therefore, the fuel engine itself does not participate in the vehicle driving process. (Such as BMW i3 extended range, Chevrolet Wo Luda) Pure electric car is relatively simple, the vehicle drive completely rely on the motor to complete, the car is not equipped with any traditional internal combustion engine, and electric power required by the motor from the car carrying the battery. (Such as Tesla model s, Nissan Leaf wind, Renault zoe are all such models) Back to Topic: Hydrogen Fuel Cell Car. Although the name is very long, but in a nutshell, it is more like an extended-range electric car. Some people may think that hydrogen fuel cell vehicles are powered by burning hydrogen feedstock. In actual fact, hydrogen fuel cell refers to the hydrogen through the chemical reaction with oxygen, thereby generating electricity device. (Hydrogen-powered diesel locomotives, driven solely by burning hydrogen, have also appeared, such as the BMW Hydrogen 7 Series) The driving force of hydrogen fuel cell vehicles from the car's electric motor, just like a pure electric car. So it can be understood as a "self-contained hydrogen fuel generator electric car." The concept is similar to that of the extended-range model, except that the source of electrical energy is changed from a single fuel-fired engine to a hydrogen fuel-powered one. How does a hydrogen fuel cell car work? At present, each car-owned hydrogen fuel cell vehicles in the basic principle is more consistent, but the details of the design are different. The following Xiaobian Toyota just released hydrogen fuel cell car mirai as an example, to parse the hydrogen fuel cell car "secret." Mirai's powertrain is called the toyota fc stack, the Toyota Fuel Cell Stack, a complex hybrid system that uses a fuel cell stack as its core component. Also includes fuel cell booster, high pressure gas tank and drive motor and other parts. Fuel cell stack is located in the lower body, hydrogen and oxygen react to the place, but also the key to hydrogen fuel cell vehicles. In the fuel cell stack, a hydrogen-oxygen combined reaction occurs, during which charge transfer occurs, creating an electrical current. In the meantime, hydrogen monoxide, ie, water, is formed just after the chemical reaction between hydrogen and oxygen. Molecular Sieve Filling Machine
