People today are becoming more concerned about protecting their health and living environment. As a result, safer and ecofriendly materials gradually take the place of petroleum-based fuel. As alternative fuel vehicles become more prevalent, hydrogen car is one of them. In this article, we will introduce hydrogen cars, including what they are, how they operate, and some common examples.
What is hydrogen powered cars?
Hydrogen powered cars are automobiles that run on hydrogen engine, also known as fuel-cell vehicles. Fuel cell electric vehicles (FCEVs) use electricity to power an electric motor, just like fully electric vehicles do. Unlike other electric vehicles, FCEVs produce their own electricity with a fuel cell powered by hydrogen rather than simply relying on a battery.
Pure hydrogen gas kept in a tank on the vehicle is used to power FCEVs. They can refuel in less than 4 minutes and have a driving range of more than 300 miles, just like traditional internal combustion engine vehicles. Other cutting-edge technology, including as regenerative braking systems that collect the energy lost during braking and store it in a battery, are included in FCEVs to boost efficiency. Major automakers are releasing fewer but more FCEVs for sale to the public in some areas, corresponding with the infrastructure’s capacity for growth.
How hydrogen cars work?
The polymer electrolyte membrane (PEM) fuel cell is the most popular kind of fuel cell used in automotive applications. An electrolyte membrane is positioned between a positive electrode (cathode) and a negative electrode in a PEM fuel cell (anode). The cathode receives oxygen from the air, whereas the anode receives hydrogen. An electrochemical process takes place in the fuel cell catalyst, causing the hydrogen molecules to split into protons and electrons. The membrane then allows protons to go to the cathode.
The protons, electrons, and oxygen molecules recombine with each other on the cathode side to produce water after the electrons are forced to go through an external circuit to perform work (powering the electric car).
Some examples of cars powered by hydrogen
Following the world’s new trend, Toyota developed a hydrogen-powered vehicle called Toyota Mirai. The first-generation Toyota Mirai, which was introduced in 2014, demonstrated the potential for using hydrogen to power clean and sustainable mobility on a worldwide scale by combining driving distance, refilling time, and emissions of only water. Toyota Mirai based on a Lexus platform and is a stylish car. The Fuel Cell Stack, located at the center of the Mirai, is where air from the intake grille and hydrogen from the fuel tank meet. There, hydrogen and airborne oxygen undergo a chemical reaction to produce electricity, which powers the Mirai. Water is the only output at the end.
The NEXO is a hydrogen fuel cell SUV that is truly fantastic and combines cutting-edge technology, futuristic style, and a great driving range.
The Hyundai Nexo’s electric motor, which is capable of producing 161 horsepower and 291 lb-ft of torque, is run by a 95 kW fuel cell stack and a 40 kWh battery pack. The motor drives the front wheels through a single-speed transmission. The Nexo takes 8.4 seconds to accelerate from 0 to 60 mph. This is faster than Toyota Mirai, but slower than Honda Clarify when compared to its competitors.
The Honda FCX Clarity is a hydrogen fuel-cell electric car that is based on the Honda FCX Concept from 2006. The FCX Clarity was a big sedan with all the features of an electric car, including zero emissions, five-minute refueling, and long range. It was the first hydrogen fuel cell car that was sold to the general public.
100 kW Honda Vertical Flow (V Flow) hydrogen fuel cell stack, which provides electricity on demand, powers the FCX Clarity. The automobile combines regenerative braking and a different battery to store energy recovered during braking, like many electric vehicles do.
Even though hydrogen-powered vehicles are still a relatively new type, numerous automakers have embraced the trend and released models to meet consumer demand. The future of hydrogen fuel vehicles is still doubtful, but it also offers hope. Stay with us to keep up with the most recent news!
