Overview
ABSTRACT
Mobility is evolving both technologically and socially. We are witnessing a rapid shift to electric mobility, mainly today, with battery. A lack of autonomy and charge time too long are often cited as the main obstacles to the development of electric vehicles. Fuel cell vehicles with hydrogen storage in compressed form at 350 or 700 bars can travel more than 500 km, in a single charge lasting 3 to 5 minutes, they appear more than ever as a credible alternative to current vehicles and complementary to batterie electric vehicules. This article discusses fuel cell technology applied to land transportation by analyzing technological and hydrogen refuelling.

INTRODUCTION
A hydrogen-powered electric vehicle is first and foremost an electric vehicle, operating with an electric powertrain identical to that used in battery-electric vehicles, which are already widely used. There is no reason to contrast battery-electric vehicles with hydrogen fuel cell electric vehicles. The only difference is how energy is stored and delivered to the electric motor. In a battery-electric vehicle, energy and power come from the battery. In a fuel cell vehicle (FCV), energy is stored as hydrogen in a tank, and power is determined by the size of the fuel cell, which generates the electrical energy for the motor. To enable regenerative braking, these vehicles use a buffer battery; they are primarily hybrid vehicles.
