No refueling, no charge, no emissions, the only emission of waste is pure water! Toyota Mirai is such a car. With the continuous consumption of oil resources, the traditional fuel vehicles in the future will be replaced by new energy is a foregone conclusion. And to say in the field of new energy vehicles who have the most say, I believe many people think of Toyota; has been mass production and the introduction Sensor of several generations of Prius Although still in the burning of oil, but it can not be denied that the development of new energy vehicles The meaning is quite huge. And the Toyota brought us the Mirai hydrogen fuel cell car is the future of the car directly visualization of the show in front of us.
Compared with the current domestic hot electric vehicles, hydrogen fuel cell has a higher energy density (about 7 times the volume of the traditional battery), filling more efficient and other advantages. And from China's current power generation structure, hydrogen fuel cell for the significance of environmental protection is far more than a car to reduce the carbon emissions so simple. As a mass production of hydrogen fuel cell vehicles, and we have seen before the hydrogen car and what is the difference? In fact, this problem is very simple, hydrogen fuel cell vehicles through Fuel Rail Pressure Sensor the hydrogen to generate electricity, and ultimately drive the vehicle is the motor; and before the appearance of the hydrogen car (it is through the hydrogen fuel-based internal combustion engine directly drive the vehicle.
Mirai's driving is through the hydrogen and oxygen in the fuel cell reactor react, produce electricity to drive the motor, and ultimately drive the vehicle. Because the hydrogen molecules are small, they can pass through the tiny pores of the membrane to the opposite side, but during the process of passing through the pores, the electrons are stripped from the molecules, leaving only positively charged hydrogen protons through which the protons are attracted to the film The other side of the electrode and oxygen molecules. Electrode film on both Temperature Sensor sides of the electrode plate to hydrogen into hydrogen ions (positive) and electrons, the oxygen is divided into oxygen ions (negative) and electrons, electrons in the electrode plate between the formation of current, two hydrogen ions and an oxygen Ion combined into pure water, is the reaction of waste. So in essence, the entire operation process is the power generation process.
