![]() So, in order to obtain the quantity of hydrogen needed to power a vehicle, it is necessary to store a considerable amount in large tanks at high pressure. How much does a hydrogen fuel cell electric vehicle consume? Bear in mind that the hydrogen atom, two of which are required to make up the dihydrogen (H2) molecule, is one of the simplest and lightest natural elements on the periodic table (the classification which lists all the chemical elements present on Earth.) It has very low volume density. The energy consumption of a hydrogen fuel cell vehicle When it comes to replenishing the hydrogen, fueling takes place at dedicated stations using pumps that inject hydrogen, extremely quickly, into the vehicle’s tank in the form of pressurized gas. The resulting energy produced, as well as energy from the battery, power the car’s electric motor, which is then able to run silently and with zero pollutant or CO2emissions*. These two gases then undergo an electrochemical reaction inside the cell, in turn producing electricity, heat and water vapor (H2O), which is released in the form of a gas via a small tube located underneath the vehicle. The gas (H2), along with dioxygen (O2) from the surrounding air, are supplied to the fuel cell. Pressurized hydrogen is stored in special tanks onboard the vehicle. How does the hydrogen fuel cell vehicle work in practice? Its electric energy is supplied by a fuel cell. How the hydrogen electric vehicle works using a fuel cell This extraction method is a solution for the future. Where the electricity used in the electrolysis process is from a sustainable energy source, like solar or wind power, it is possible to produce “green” hydrogen. The current method of extracting this chemical element relies on the steam reforming of hydrocarbons, and is called “grey” hydrogen because it is extracted from fossil fuels.īut there is another way to obtain hydrogen: through water electrolysis. That said, there still remain several challenges to overcome in order to reduce the environmental impact of hydrogen production as much as possible. The hydrogen-powered car shares the same emission-free driving ambitions as the “conventional” electric vehicle. The majority of hydrogen vehicles currently produced by automobile manufacturers work in this way. The electricity required to run the powertrain is not only supplied by the battery, but also by the fuel cell using hydrogen stored onboard the vehicle. Herein lies the difference with the hydrogen vehicle. For an electric car powered by a lithium-ion battery, electrical energy is simply stored in the battery after charging on the electrical grid. The hydrogen fuel cell vehicle belongs to the large family of electric cars, as it gets its traction from an electric powertrain. The term “hydrogen electric car” refers to a vehicle powered by a specific energy source - hydrogen - using a special device: the fuel cell. So what are the particularities of a hydrogen vehicle? How does it work? What are its advantages? And, more concretely, what are the possible uses of a hydrogen car in everyday life? The challenges of the hydrogen electric car ![]() While, for many, the term “fuel cell” might sound like complex advanced technology, the secret to this new way of producing energy lies in a simple chemical reaction between oxygen and hydrogen.
