The principle of the hydrogen car
The hydrogen car (or fuel cell car) produces its own electricity continuously thanks to an electric motor according to the needs of the motor. The principle of operation is quite simple: the car uses a fuel cell (PAC) powered by the hydrogen tank, a battery and an inverter to change the direction of current flow. The engine oxidizes the hydrogen stored in gaseous form in order to produce this electrical energy.
In other words, when the hydrogen produced arrives in these cells, it is pushed with high pressure to through a platinum catalyst. It is then split into two ions and two electrons, which supplies energy to the car's electric motor and enables the production of electricity. Hydrogen, combined with oxygen, will create a condensation phenomenon. As a result, the muffler only releases water!
When starting or at low speed, the vehicle is driven by the battery. However, when it needs more power, on a highway for example, hydrogen enters the fuel cell to produce electricity. When the vehicle is in a deceleration phase, the inverter will transform the recovered energy into electricity, which then allows the battery to be recharged.
The production of fuel for this type of vehicle is quite complicated and not environmentally friendly. Hydrogen gas is generally produced in power plants through a process of hydraulic fracturing. The steam is combined with methane and heated to very high temperatures to produce hydrogen, carbon monoxide and CO2.
An ecological advantage
A hydrogen vehicle has the main advantage of being ecological, "zero emissions". Indeed, it is a type of automobile that does not directly consume fossil fuels and does not emit carbon dioxide and no air pollutants. A car with such an engine emits only water vapor and is therefore not polluting at all!
The hydrogen engine makes no noise! The vehicle makes almost no noise. Indeed, the fuel cell as well as the electric motor, even at full power, remain relatively silent.
Fast recharging
As for recharging time, hydrogen vehicles require very little time compared to electric cars. In addition, this type of automobile is much more autonomous than an electric car, since with a "full" you can cover up to 650 km, compared to 150 km on average. And to charge it five minutes is enough, compared to almost overnight for an electric vehicle. It actually works like a gas station: the driver gets supplies at the pump.
Take for example a Honda Clarity Fuel Cell which, as a hydrogen car, takes only 10 minutes to recharge. fully while refueling a Tesla Model S P100D takes an average of an hour to be done with a powerful charger.
But some drawbacks…
In the future, hydrogen may therefore become a good means of storing electricity when renewable energies are used extensively.Nevertheless, there are some drawbacks associated with this type of vehicle, in particular because of its type of electricity supply. 'hydrogen. Here are some below:
Type of energy used for the production of clean hydrogen (hydrocarbons, uranium) Dihydrogen storage problem (high pressures or very low temperatures) Lack of hydrogen distribution infrastructure ( charging stations)
