Fuel cell cars are electric vehicles that use hydrogen as their power source, rather than electricity from batteries or a plug-in source. Hydrogen fuel cell cars are powered by the most abundant element in the universe: hydrogen. Hydrogen fuel cell cars have a similar range to electric cars with large battery storage, but without the weight of batteries. Hydrogen fuel cell cars are also more efficient than their electric counterparts, as they produce their own electricity.

Hydrogen fuel cell cars are powered by electricity, but work differently from battery-powered cars
Hydrogen fuel cell cars are powered by electricity and classified as e-cars. However, they work differently from battery-powered cars, or Battery Electric Vehicles (BEVs). Hydrogen fuel cell cars produce electricity themselves using an onboard fuel cell stack, instead of relying on a built-in battery charged by an external power source.
The fuel cell stack combines hydrogen and oxygen to generate electricity and power the electric motor. Hydrogen is stored in carbon-fiber reinforced tanks inside the car, and the amount of energy stored is determined by the size of the hydrogen fuel tank. This is different from battery-powered cars, where the amount of power and energy available are closely related to the battery's size.
The hydrogen gas in the fuel tank does not burn but transforms the fuel's chemical energy into electrical energy through an electrochemical reaction. This electricity then powers the car's electric motor. The byproduct of this reaction is water vapour, which is emitted through the exhaust.
The electric motor in a hydrogen fuel cell car drives the vehicle's wheels, similar to a battery-electric car. However, the power in a hydrogen fuel cell car comes from the fuel cell and a traction battery pack, with the latter providing extra power during acceleration and recapturing braking energy. The experience of driving a hydrogen fuel cell car is almost identical to driving a battery-electric vehicle, although hydrogen fuel cells are most efficient at a steady power output.

Hydrogen fuel cell cars are more expensive to acquire than conventional cars of a similar size
Hydrogen fuel cell cars are electric cars that run on electricity produced by combining hydrogen and oxygen in a fuel cell. They are powered by the most abundant element in the universe, hydrogen, and produce zero tailpipe emissions, with the only waste being pure water.
While hydrogen fuel cell cars have numerous benefits, they are more expensive to acquire than conventional cars of a similar size. This is primarily due to the high cost of the fuel cell stack, a crucial component of the car's system. The manufacturing process of the fuel cell stack is complex and requires extreme precision, making it expensive. Additionally, hydrogen fuel cell cars require at least two Composite Overwrapped Pressure Vessels (COPVs) capable of storing hydrogen at high pressures, adding to the overall cost.
The complexity of the fuel cell system also contributes to the higher cost of these vehicles. In addition to the fuel cell stack and COPVs, hydrogen fuel cell cars need an air compressor or pump, an expander for hydrogen, a water de-ionizer, a mechanism to add water to the intake, an air filter, and a transformer to handle the high voltage. The combination of these components results in a costly system.
Furthermore, the cost of hydrogen fuel itself is a significant factor in the higher acquisition price of hydrogen fuel cell cars. Producing "green hydrogen", which uses clean electricity to extract hydrogen from water, is currently a costly process. As a result, the total cost of ownership for a hydrogen fuel cell car is higher than that of a comparable gasoline vehicle or electric vehicle (EV).
However, it is important to note that leasing options for hydrogen fuel cell cars often include fuel, service, and maintenance, which can make the total cost of ownership comparable to conventional cars. Additionally, government incentives, such as rebates and clean vehicle projects, can help offset the higher acquisition cost of hydrogen fuel cell cars.

Hydrogen fuel cell cars are classified as e-cars and produce their own electricity
Hydrogen fuel cell cars are a type of electric car, commonly abbreviated as FCEV, which stands for "Fuel Cell Electric Vehicle". Unlike battery-powered electric cars, or BEVs, which are charged by an external power source, hydrogen fuel cell cars produce their own electricity through a process known as reverse electrolysis. In this process, hydrogen from the car's tank reacts with oxygen from the ambient air, generating electrical energy, heat, and water vapour. This electricity then powers the car's electric motor, with the water vapour being emitted through the exhaust.
The fuel cell stack, which combines hydrogen and oxygen to generate electricity, is the power plant of a hydrogen fuel cell car. This electricity is then managed by a power electronics controller, which controls the speed and torque of the electric traction motor. The fuel tank, electric motor, power electronics, and other components are all kept within a suitable temperature range by a thermal cooling system.
Hydrogen fuel cell cars have several advantages over conventional cars and BEVs. Firstly, they have a similar range to e-cars with very large battery storage, with a single refuelling providing up to 504 kilometres of travel distance. Additionally, their range does not depend on outside temperature, meaning it does not deteriorate in cold weather. Hydrogen fuel cell cars are also very energy-efficient, produce no emissions, and are quiet.
Another benefit of hydrogen fuel cell cars is their refuelling process. They can be refuelled as quickly as a standard car's gas tank and can carry enough fuel for 300-400 miles of range. While hydrogen fuel currently sells for considerably more than gasoline, a fuel cell car can travel about twice as far as a conventional car with the same amount of fuel. Furthermore, leasing a hydrogen fuel cell car can include up to three years of complimentary fuel, making the total cost of ownership comparable to conventional cars.
While hydrogen fuel cell cars have a higher upfront acquisition cost than similarly-sized conventional cars, they offer long-term benefits. Their refuelling infrastructure is constantly being expanded worldwide, and marketing hydrogen cars benefits both fuel cell and battery technologies, leading to reduced costs in the long term. Additionally, current leasing packages often include fuel, service, and maintenance, making them a competitive option in the market.

Hydrogen fuel cell cars are powered by the most abundant element in the universe: hydrogen
Hydrogen fuel cell cars are powered by hydrogen, the most abundant element in the universe. Hydrogen fuel cell cars are electric cars that run on electricity generated by the onboard recombination of hydrogen and oxygen from the atmosphere. This onboard generation of electricity is what differentiates hydrogen fuel cell cars from battery-powered or plug-in hybrid cars.
In a hydrogen fuel cell car, hydrogen is stored in gaseous form in carbon-fiber-reinforced tanks. The hydrogen gas is then fed into an onboard fuel cell stack that transforms the fuel's chemical energy into electrical energy. This electrical energy then powers the car's electric motors. The byproduct of the reaction occurring in the fuel cell stack is water vapour, which is emitted through the exhaust.
The construction of the fuel cell is similar to a battery. Hydrogen enters the anode, where it comes in contact with a catalyst that promotes the separation of hydrogen atoms into electrons and protons. The electrons are gathered by the conductive current collector, which is connected to the car's high-voltage circuitry, feeding the onboard battery and/or the motors. The power electronics controller (FCEV) manages the flow of electrical energy delivered by the fuel cell and the traction battery, controlling the speed of the electric traction motor and the torque it produces.
Hydrogen fuel cell cars have several advantages over traditional internal combustion engines. Firstly, they produce zero tailpipe emissions, with the only waste product being pure water. Secondly, they have a long range, with a single hydrogen refuelling providing up to 504 kilometres of driving distance. Additionally, their tanks can be refilled as quickly as a standard car's gas tank. Furthermore, hydrogen fuel cell cars are quiet and very energy-efficient, with similar range and performance to their gasoline counterparts.
