The Toyota Mirai is a hydrogen fuel cell car
The Toyota Prius is a hybrid electric vehicle, and while it is not a fuel cell car, Toyota has been developing hydrogen fuel cell technology since the Prius was first unveiled in 1993. The Toyota Mirai, on the other hand, is a hydrogen fuel cell car.
The 2025 Toyota Mirai is a hydrogen-powered car that combines hydrogen with oxygen from the outside air to generate electricity and power the car. This process does not create any tailpipe emissions, only water. The Mirai uses an onboard fuel cell to convert hydrogen gas into electricity, which is then routed to a 182-hp electric motor. This electric vehicle does not rely on high-capacity batteries or charging stations, making refuelling a quick and simple process.
The Mirai is part of Toyota's Fuel Cell EV Family, which includes various electrified powertrains such as Hybrid EV, Plug-in Hybrid EV, Battery EV, and Fuel Cell EV. Toyota's vision, called "Beyond Zero", aims to achieve carbon neutrality with its products, services, and operations. The Mirai is one of the ways the company is working to reduce carbon emissions and create a positive impact on the planet and society.
The Mirai has been praised for its impressive range, refined ride, and Lexus-like interior. However, it is only available in California due to the limited number of hydrogen fuelling stations in other states. Toyota has been selling the Mirai since 2015, and the car is now in its second generation. In 2021, the second-generation Mirai set a world record by travelling 845 miles with a full tank of hydrogen.
The Mirai has undergone extensive crash testing to ensure the safety of its occupants and protect the fuel cell stack and high-pressure tanks in the event of a collision. The hydrogen tanks and related parts are located outside the cabin to ensure that any leaked hydrogen dissipates easily. The Mirai's hydrogen fuel tanks have been rigorously tested and meet Global Technical Regulation No. 13.

Hydrogen fuel cell technology combines stored hydrogen and oxygen to generate electricity
The basic principle behind hydrogen fuel cell technology is to combine stored hydrogen and ambient oxygen to generate electricity to power an electric vehicle. This process involves a chemical reaction where hydrogen from the fuel tank and oxygen from the air meet in the Fuel Cell Stack, creating electricity. The hydrogen molecules are separated into protons and electrons, which take different paths to the cathode, resulting in a flow of electricity.
Fuel cells have a variety of potential applications and can be used in multiple sectors, including transportation, industrial, commercial, and residential buildings. They can also be utilized for long-term energy storage and in power plants as a supplemental or backup power supply. Additionally, fuel cells can operate at higher efficiencies than combustion engines and can directly convert chemical energy into electrical energy with efficiencies exceeding 60%.
One of the critical advantages of hydrogen fuel cells is their environmental impact. They emit only water and produce no carbon dioxide emissions or air pollutants, making them an attractive option for zero-emission vehicles. However, the high cost of fuel cells and the limited availability of hydrogen fueling stations have hindered the widespread adoption of hydrogen-fueled vehicles. Nevertheless, initiatives like California's Advanced Clean Cars Program aim to address this challenge by promoting the establishment of publicly accessible hydrogen vehicle fueling stations.
Toyota has been a pioneer in electrified vehicles, with the Prius being a well-known example. The company continues to invest in hybrid and plug-in hybrid electric vehicle technology while also exploring hydrogen fuel cell technology. The Mirai, in particular, showcases Toyota's commitment to reducing environmental impact and providing consumers with efficient and environmentally friendly transportation options.

Hydrogen fuel cell vehicles emit only water vapour
Hydrogen fuel cell vehicles (HFCVs) emit only water vapour and warm air, producing no harmful tailpipe emissions. This is because hydrogen is an energy carrier that can be produced from various feedstocks. The process involves combining stored hydrogen and ambient oxygen to generate electricity to power an electric vehicle.
Toyota has been at the forefront of developing hydrogen fuel cell technology, with its Mirai model being a prominent example. The Mirai, first introduced in 2019, runs on electricity created by a chemical reaction between hydrogen from the fuel tank and oxygen from the intake grille. While the vehicle itself is not a performance marvel, it is a practical family car that can travel over 400 miles on a single tank and has gained popularity worldwide.
However, it is important to note that the widespread adoption of hydrogen fuel cell cars faces several challenges. Hydrogen fuelling stations are expensive to build and have a lower daily vehicle servicing capacity compared to modern gas stations. Additionally, hydrogen cars tend to be heavier and slower than electric cars, and the fuel cell lifespan is shorter. These factors contribute to the low sales of hydrogen cars, representing only 0.02% of global passenger vehicle sales last year, according to BloombergNEF.
Despite these challenges, hydrogen fuel cell technology has the potential to drastically reduce emissions. Toyota, for instance, has expressed its commitment to reducing its environmental footprint through its "Beyond Zero" vision, which includes the development of hydrogen fuel cell vehicles as a key component.
In summary, hydrogen fuel cell vehicles emit only water vapour, and their adoption could play a significant role in transitioning to more sustainable transportation options. However, the technology also faces several obstacles, including fuelling infrastructure limitations and vehicle performance considerations.

Hydrogen fuel cell vehicles are safer than combustion engine vehicles
Hydrogen fuel cell vehicles are much safer than combustion engine vehicles. Hydrogen fuel cell vehicles, like the Toyota Mirai, are fuelled with pure hydrogen gas stored in a tank on the vehicle. In the event of a leak or collision, the hydrogen tank valves are designed to automatically close to prevent more hydrogen from escaping, with any leaked hydrogen returning safely to the atmosphere. This means that hydrogen fuel cell vehicles do not pose a risk of explosion or fire in the event of an accident, which is a common risk associated with combustion engine vehicles.
Another safety advantage of hydrogen fuel cell vehicles is that they emit only water vapour as a byproduct, whereas combustion engine vehicles emit harmful pollutants such as nitrogen oxides (NOx) and particulate matter (PM). These pollutants can have negative impacts on human health, contributing to respiratory and cardiovascular diseases. By choosing a hydrogen fuel cell vehicle, drivers can have peace of mind knowing that they are not contributing to air pollution and its associated health risks.
Furthermore, hydrogen fuel cell vehicles are often equipped with advanced safety technologies to increase their efficiency and performance. For example, regenerative braking systems capture the energy lost during braking and store it in a battery, improving the vehicle's overall energy efficiency. This not only enhances the vehicle's range but also contributes to a more sustainable driving experience. Hydrogen fuel cell vehicles are also known for their quiet operation, providing a more comfortable and peaceful driving experience compared to the loud engine noises of combustion engine vehicles.
While hydrogen fuel cell vehicles have lower sales than traditional combustion engine vehicles, they are gaining traction as a safe and environmentally friendly alternative. Toyota, for example, has sold roughly 14,300 Mirai sedans across two generations in the US. The Mirai can travel more than 400 miles per tank and refuel in about 5 minutes, making it a practical and efficient choice for drivers. With Toyota's commitment to reducing carbon emissions and its leadership in alternative fuel vehicles, we can expect to see continued advancements and improvements in hydrogen fuel cell technology.
