Hydrogen fuel cell cars are an innovative technology that offers a zero-emission alternative to traditional internal combustion engines and battery-powered electric vehicles. These cars use hydrogen fuel cells to generate electricity and power the electric motor, resulting in reduced pollution, lower noise levels, and dynamic driving performance. Unlike battery-powered electric vehicles, hydrogen fuel cell cars produce their own electricity, eliminating the need for lengthy charging times. This technology is being rapidly adopted by the automotive industry to meet sustainability targets and consumer demands for environmentally friendly options. With their fast refuelling, lightweight design, and long-range capabilities, hydrogen fuel cell cars are poised to revolutionize the future of transportation, offering a practical and efficient solution for both passenger vehicles and commercial fleets.

Hydrogen fuel cells
Hydrogen fuel cell cars are powered by an electric motor and are classified as e-cars. They are often referred to as FCEVs, or "Fuel Cell Electric Vehicles". Hydrogen fuel cell cars differ from other electric vehicles in that they produce electricity themselves. This means that their power does not come from a built-in battery, as is the case with purely electric vehicles or plug-in hybrid vehicles. Instead, hydrogen cars have their own power plant on board, which converts the hydrogen in the fuel tank into electricity.
In a hydrogen fuel cell, hydrogen and oxygen are combined in an electrochemical reaction to produce electricity, with heat and water vapour as by-products. The hydrogen comes from one or more tanks in the car, while the oxygen comes from the ambient air. The electricity generated in the fuel cell takes two routes, depending on the driving situation. It flows to the electric motor and directly drives the vehicle, and/or it charges a battery that acts as temporary storage until the energy is needed for driving. This "buffer" battery is significantly smaller and lighter than the battery of an all-electric car. Hydrogen fuel cell cars can also recover braking energy.
Hydrogen fuel cell cars are emission-free and have fast refuelling times, making them ideal for larger vehicles such as SUVs and long-range buses and trucks. They are also much quieter than internal combustion engines, reducing noise pollution in busy areas.

Electric motors
Hydrogen fuel cell cars are powered by an electric motor and are classified as e-cars. They use the same kind of electric motor to turn the wheels as a battery-electric car. However, instead of being powered by a large, heavy battery, they are powered by a fuel-cell stack. Hydrogen is stored in tanks on the vehicle and converted onboard into electrical energy through a process known as reverse electrolysis.
In this process, hydrogen reacts with oxygen from the ambient air to produce electricity, heat, and water vapour. The electricity generated in the fuel cell can either be used to power the electric motor directly or to charge a battery that acts as a temporary store of energy. This "buffer" battery is smaller and lighter than the battery of an all-electric car and is constantly recharged by the fuel cell.
The amount of energy stored onboard is determined by the size of the hydrogen fuel tank, and the power of the vehicle is defined by the size of the electric motor(s) that receives electric power from the appropriately sized fuel cell and battery combination. Hydrogen fuel cell cars can also recover or "recuperate" braking energy, providing extra power during short acceleration events.
Fuel cell cars have several advantages over battery-electric vehicles. They have a longer range and faster refuelling times, and the fuel cells are 95% recyclable, unlike batteries, which have a significant carbon lifecycle footprint and reduced recyclability. Hydrogen fuel cell cars also do not depend on electrical charging, reducing the impact on the electrical grid from mass vehicle charging.

Zero emissions
The development of hydrogen fuel cells for cars has been driven by zero-emission legislation and increasing consumer interest in sustainable mobility. As a result, the global automotive industry is rapidly accelerating the development and production of electric vehicles. Intelligent Energy, a UK-based company, has unveiled a new hydrogen fuel cell system that is smaller and more powerful than any other solution on the passenger car market. This breakthrough technology has the potential to unlock a global, zero-emission future for the automotive sector.
The IE-DRIVE™ product is a fuel cell system designed for passenger cars and light commercial vehicles. It provides maximum flexibility for installation due to its modular design. The system is capable of 157kW gross electrical power, higher than any other single-stack application available for the passenger car sector. The heat exchanger in the IE-DRIVE™ system is also 30% smaller than its competitors, improving vehicle packaging and fuel cell vehicle design.
The adoption of hydrogen fuel cell technology by car manufacturers is expected to have significant economic benefits. The global fuel cell market for passenger cars and vans is anticipated to be worth $750 billion by 2040. Scaling up manufacturing capability will create new employment opportunities and provide a boost to the regional and national economy. Additionally, the transition to zero-emission vehicles will contribute to the fight against climate change and improve air quality.

Fuel cell stack
The fuel cell stack is the heart of the fuel cell system and forms its core. It consists of a stack of up to several hundred fuel cells. Each cell contains a membrane electrode assembly (MEA) and two flow-field plates, delivering between 0.5 and 1V of voltage.
In each cell, a "cold combustion" process takes place. This process involves a chemical reaction between the continuously fed hydrogen from the fuel tank and oxygen from the air. The hydrogen is catalytically split into electrons and protons. The protons diffuse through a polymer membrane towards the cathode, while the electrons flow from the anode to the cathode via an electrical circuit, supplying the consumer with an electric current. At the cathode, the protons, electrons, and oxygen react to form water.
This reaction produces only electrical energy, heat, and water vapour, with no harmful emissions. The electricity generated in the fuel cell stack powers the electric motor of the vehicle directly and/or charges a battery for temporary storage.

Hydrogen refuelling
Vehicle manufacturers such as BMW have joined forces with hydrogen producers and filling station operators to help expand the infrastructure. Hydrogen is refuelled through special pumps, and the process is very quick, taking just a few minutes. This is one of the key benefits of hydrogen fuel cell cars over electric battery vehicles, which can take much longer to recharge.
The hydrogen is stored in tanks on the vehicle and converted into electrical energy through a process known as reverse electrolysis. This reaction produces electrical energy, heat, and water vapour, with no harmful emissions. The electricity generated then powers the electric motor of the vehicle.

Frequently asked questions
A fuel cell car is an electric vehicle that uses a fuel cell stack to power the electric motor. The fuel cell stack combines hydrogen and oxygen from the air to produce electricity through a process known as reverse electrolysis. The electricity generated then powers the electric motor directly or charges a small "buffer" battery that acts as a temporary store of energy.
Unlike electric cars, fuel cell cars do not rely on large, heavy batteries that need to be charged from an external power source. Instead, fuel cell cars produce their own electricity and can be refuelled at hydrogen filling stations in a similar way to petrol and diesel cars.
Fuel cell cars are zero-emission vehicles, with the only by-products being water vapour and heat. They are also much quicker to refuel than electric cars, taking around 3 to 5 minutes, and do not contribute to the strain on the electrical grid. Additionally, fuel cells are 95% recyclable, improving sustainability within the transport sector and reducing the need for scarce materials used in batteries.
