Behind Toyota's hydrogen car, two high-pressure gas tanks are installed. Toyota has developed 290 patented technologies for this fuel tank alone. The outermost layer is wrapped with carbon fiber material, which is the cutting-edge material for manufacturing passenger aircraft fuselage, light and strong. Toyota's hydrogen car has no engine, only a small motor is installed in the front. The working principle of fuel cell power system is that hydrogen reacts with oxygen to generate electric energy, and then drives the motor to run. The so-called fuel cell is a stack installed in the middle of the car, called "FC stack". This pile is not a battery, but a power generation device. Hydrogen and oxygen react here to produce kinetic energy, and this reactor has no life limit. There is a battery at the rear of the car, which is the regenerative electric energy accumulated during driving. These regenerated electric energy can also be used for driving. How is hydrogen added? The inflation port is in the same position and the same concept as the inflation port of ordinary cars, but it is a very small air intake. Generally speaking, there will be no accidental air leakage in the hydrogenation process, because the hydrogenation system is an automatic control system, even if there is a little air leakage in the hydrogenation process, it will evaporate quickly and will not cause problems such as combustion. It only takes 3 minutes to refuel a car. Adding primary gas can run 650 kilometers, and the FC stack as a generator will not have the problems of battery aging and power decline.
