Fuel cell cars are powered by an electric motor and are classified as e-cars. They are similar to electric vehicles (EVs) but have specific differences that set them apart. One of the most notable differences is that fuel cell cars do not require transmission and, therefore, do not need gears. This means that, unlike traditional cars, you won't feel a fuel cell car change gears when accelerating or climbing hills. Instead of using a transmission, fuel cell cars use regenerative braking to recapture wasted energy as the car slows down.

What You'll Learn
Hydrogen fuel cell vehicles are electric cars
Hydrogen fuel cell vehicles (HFCVs) are electric cars that use hydrogen and oxygen to produce electricity. They are powered by an electric motor and are classified as e-cars. HFCVs have a similar range to e-cars with large battery storage, but differ in the way they store energy. While e-cars store energy in batteries, HFCVs use hydrogen fuel cells to generate electricity on-board. 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, which can be charged from an external power source. Instead, HFCVs have their own power plant on board, which converts the hydrogen in the fuel tank into electricity.
HFCVs combine the performance and emissions-free driving of an electric vehicle with the range and convenience of a traditional vehicle. They are zero-emission, zero-petroleum vehicles with similar range, refill time, power, and performance to conventional vehicles. HFCVs are also very quiet. The only emission from HFCVs is pure water vapour, which is so clean that it can be drunk.
HFCVs are energy efficient and significantly reduce greenhouse gas emissions and air pollutants. They have no transmission and include regenerative braking to recapture wasted energy when slowing down. The challenge for automotive engineers is that hydrogen fuel cells are most efficient at a steady power output. This makes them suitable for backup power use, but less ideal for driving, which requires varying levels of power output.
HFCVs are much rarer than electric vehicles. As of mid-2022, there were 17,000 or fewer hydrogen-powered vehicles on US roads, all in California, the only state with a network of retail hydrogen fuelling stations. By contrast, almost three million EVs have been sold in the US. HFCVs are also currently more expensive than comparable e-cars with batteries or internal combustion engines due to the high cost of industrialization in production and the demand for platinum. However, automakers like Toyota and Honda are giving hydrogen away for free for the life of a lease to promote the adoption of HFCVs.

Hydrogen fuel cell vehicles are zero-emission vehicles
Hydrogen fuel cell vehicles (FCEVs) are considered zero-emission vehicles (ZEVs) as they emit only water vapour and heat during operation. They are powered by hydrogen, which is converted into electricity through a chemical reaction with oxygen in a fuel cell. This electricity then powers an electric motor that drives the vehicle. The only byproduct of this process is water, which is so pure that it can even be consumed.
FCEVs are similar to battery electric vehicles (BEVs) in that they are both electric vehicles (EVs) that use an electric motor to power the wheels. However, BEVs run on batteries that need to be plugged in to recharge, while FCEVs produce their electricity onboard through the chemical reaction between hydrogen and oxygen. This gives FCEVs a range, refill time, power, and performance similar to conventional vehicles, making them a more convenient option than BEVs.
One of the main advantages of FCEVs is their potential to significantly reduce greenhouse gas (GHG) emissions and air pollutants in the transportation sector. By emitting only water and heat, FCEVs produce no smog-related or tailpipe emissions, making them a much cleaner alternative to traditional internal combustion engines. This makes them particularly suitable for heavy-duty transportation applications such as long-haul trucks, locomotives, and ships, where current battery technology may not be feasible.
Despite the benefits of FCEVs, there are some challenges to their widespread adoption. One major challenge is the lack of a well-established hydrogen fuelling infrastructure. Creating a new fuelling network from scratch has proven to be expensive and unreliable, and the fuel itself is currently much pricier for drivers than gasoline or electricity. Additionally, while hydrogen is abundant in the universe, producing pure hydrogen for vehicles requires a significant amount of energy and can result in carbon dioxide (CO2) and methane (CH4) emissions during the production process.
However, as hydrogen technology continues to scale up, costs are expected to decrease, and the challenges associated with hydrogen production and infrastructure are likely to be addressed. Hydrogen fuel cell vehicles have the potential to play a significant role in reducing emissions and combating climate change, particularly in the transportation sector.

Hydrogen fuel cell vehicles are rare
Hydrogen fuel cell vehicles (HFCV) are indeed rare. As of 2022, there were 17,000 or fewer hydrogen-powered vehicles on US roads, compared to almost three million electric vehicles. These vehicles are all located in California, the only state with a network of retail hydrogen fuelling stations. Since 2015, only three hydrogen-powered cars have been offered for sale: the Honda Clarity Fuel Cell, the Hyundai Nexo SUV, and the Toyota Mirai.
There are several reasons for the rarity of hydrogen fuel cell vehicles. Firstly, they are relatively expensive to produce, as their designs require rare substances such as platinum as a catalyst. This makes them more costly than comparable electric vehicles with batteries or internal combustion engines. The high prices of hydrogen fuel cell vehicles have been a significant factor in their low sales. For example, Honda has ended production of the Clarity, and Hyundai has sold only about 1600 Nexo SUVs in six years. Toyota, the company most devoted to hydrogen power, has sold roughly 14,300 Mirai sedans in the US, sometimes resorting to substantial discounting to do so.
Another factor contributing to the rarity of hydrogen fuel cell vehicles is the lack of fuelling infrastructure. Hydrogen is more difficult to store and transport than other fuels due to the small size of its molecules, and there are currently very few retail hydrogen fuelling stations. California, the only state with a significant network of these stations, had about 50 retail hydrogen stations open by the end of 2017 and aimed to have at least 100 by 2020. However, the rapid rise of electric vehicles and their associated technology and infrastructure has further reduced the scope for hydrogen-powered cars.
Despite their rarity, hydrogen fuel cell vehicles have several advantages. They are zero-emission vehicles, producing only water vapour as exhaust, and they are energy-efficient, reducing greenhouse gas emissions and air pollutants. They also have a similar range, refill time, power, and performance to conventional vehicles, and their refuelling time is comparable to that of traditional gas stations. Additionally, hydrogen fuel cell vehicles are very quiet, and their power comes from an efficient power plant onboard the vehicle, rather than a built-in battery.

Hydrogen fuel cell vehicles are safe
Hydrogen fuel cell vehicles are subject to extensive safety testing before being released on public roads. The hydrogen in the vehicle is stored in gaseous form in thick-walled tanks, which are particularly safe. Numerous crash tests have validated the safety of this design: the tanks were undamaged and no hydrogen leaked out. Hydrogen technology is not new, but is tried and tested in a range of areas. Refineries, for example, already use large quantities of hydrogen as a process gas when processing crude oil. Pipelines and storage facilities for hydrogen have also been in operation for decades.
The transportation of hydrogen for use at refuelling stations does pose additional safety risks, but these stations use sensors to monitor for leaks. There have not been any serious incidents reported in California, and the industrial sector has been transporting hydrogen for decades. According to the National Fire Protection Association, alternative-fuelled vehicles, including hydrogen fuel cell and battery-powered electric vehicles, are not more hazardous than traditional internal combustion engines.

Hydrogen fuel cell vehicles are similar to electric vehicles
Hydrogen fuel cell vehicles (HFCVs) are similar to electric vehicles (EVs) in several ways. Firstly, they are both zero-emission vehicles, with the tailpipe emissions from HFCVs being zero and the only waste produced being pure water vapour. Secondly, HFCVs and EVs are both powered by electric motors, although HFCVs are powered by a fuel cell stack that combines hydrogen and oxygen to generate electricity, while EVs are powered by batteries.
Thirdly, HFCVs and EVs have similar driving experiences, with no transmission and regenerative braking systems that capture energy lost during braking and store it in a battery. However, HFCVs are not as well-suited to high-power demands as some EVs, as hydrogen fuel cells operate best at a steady power output.
Fourthly, HFCVs and EVs have similar refuelling times, with both types of vehicles able to be refuelled in around five minutes. Additionally, both HFCVs and EVs are eligible for incentives and rebates in some regions, such as California's Clean Vehicle Rebate Project, which offers a $4,500 rebate for the purchase of an HFCV.
Finally, both HFCVs and EVs are subject to extensive safety testing before being released to the public, ensuring that they are as safe as traditional combustion engine vehicles.
