Hydrogen fuel cell vehicles (HFCVs) are an alternative to traditional fossil fuels and electric cars. They are powered by hydrogen, which combines with oxygen from the air to produce electricity and water vapour. One of the key advantages of HFCVs is their short refuelling time, which takes just 3 to 5 minutes, compared to the 30 minutes to a whole night it can take to charge an electric car. However, the availability of hydrogen fuel stations is limited, and the process of refuelling an HFCV is more complex than simply filling up a diesel or gasoline-powered car.

What You'll Learn
Refuelling an HFC car takes around five minutes
HFC cars are powered by hydrogen fuel cells, which generate electricity by combining hydrogen and oxygen in a process known as reverse electrolysis. The electricity produced powers the electric motor and drives the vehicle, with the only by-products being heat and water vapour. This makes HFC cars a zero-emissions alternative to traditional combustion engines.
While the refuelling process for an HFC car is quick, there are some challenges associated with hydrogen fuel. Firstly, the availability of hydrogen fuel can be an issue. For example, in California, there are fewer than 60 hydrogen stations, and not all of them are always available for fuelling. Additionally, hydrogen can be challenging to produce and distribute with low losses, and the infrastructure for large-scale production and distribution is still lacking.
Another consideration is the range of HFC vehicles. While a single refuelling can provide a range of around 300 to 500 kilometres, depending on the vehicle, some sources suggest that current hydrogen tanks would not allow for even 100 miles of travel on a full tank. However, HFC vehicles have the advantage of consistent performance in cold weather, as their range is not affected by outside temperature.

HFC cars are harder to fill up than diesel cars
While hydrogen fuel cell (HFC) vehicles are perceived to be a good bridge between fossil fuels and full electric, filling up an HFC car is harder than filling up a diesel car. This is mainly because hydrogen is complicated to produce and distribute with acceptably low losses. There is currently no infrastructure for distributing or making hydrogen in large quantities, and it is more complex and energy-intensive to transport and store hydrogen than it is for gasoline or diesel.
The process of refuelling an HFC car is also different from that of a diesel car. HFC vehicles are refuelled through special pumps, and the infrastructure for supplying hydrogen to retail outlets is still thin. HFC drivers are dependent on hydrogen fuelling stations, and there are far fewer of these than there are traditional fuel stations. In addition, stringent regulations in some countries, such as Japan, make it very expensive to build a hydrogen filling station.
Another challenge with HFC vehicles is that the hydrogen tanks are not very efficient with current technology. If used in a car, current hydrogen tanks would not even allow the vehicle to travel 100 miles, although they are still safe for passengers and road use. In addition, fuel cells wear out quickly and are hard to regenerate, making them more expensive.
Despite these challenges, HFC vehicles have some advantages over diesel cars. HFCs have a similar range to diesel cars, and hydrogen fuel cells are thought to last longer than batteries. In addition, refuelling an HFC vehicle is much faster than charging an electric car, taking only three to five minutes.

HFC cars have a shorter range than electric cars
Hydrogen fuel cell (HFC) vehicles are perceived to be a good bridge between fossil fuels and full electric. They are powered purely by electricity and drive with zero local emissions. The driving experience is therefore similar to that of electric cars, with dynamic, virtually silent acceleration, since electric motors provide their full torque even at low speeds. However, HFC cars have a shorter range than electric cars.
The range of an HFC car is also influenced by the amount of hydrogen that can be stored on board. The hydrogen fuel tank size determines the amount of energy available, and current technology has limitations in terms of safe and passenger-road-friendly hydrogen tanks. As a result, HFC cars may not be able to match the range of electric cars with larger battery capacities.
Additionally, the infrastructure for supplying hydrogen fuel is still developing. HFC drivers have experienced challenges due to the limited number of hydrogen stations and the time required for these stations to repressurize after fuelling a few vehicles. This can lead to situations where HFC car owners have to set alarms in the early hours to reach a fuelling station and ensure they have access to hydrogen fuel.
While HFC cars offer advantages such as short refuelling times and zero emissions, their range is currently shorter than that of electric cars due to battery size, hydrogen storage limitations, and the evolving hydrogen fuelling infrastructure.

HFC cars are more expensive than electric cars
Hydrogen fuel cell (HFC) vehicles are perceived to be a good bridge between fossil fuels and full electric. They are powered purely by electricity and drive with zero local emissions. However, HFC cars are currently more expensive than electric cars (EVs) due to various reasons. Firstly, the industrialization of HFC production is not yet fully developed, and the demand for platinum, a catalyst in electricity generation, also contributes to higher costs. While the amount of platinum required has decreased, and recycling efforts have increased the supply of recycled platinum, production costs remain high.
HFC cars are also more complex than EVs, requiring a lot of supporting systems, which makes them more prone to failure. The cost of hydrogen fuel is another factor, as it is complicated to produce and distribute hydrogen with acceptably low losses. Hydrogen is mostly extracted from natural gas, a process that creates CO2 as a byproduct, and carbon capture systems to mitigate this issue further increase costs.
In contrast, EVs benefit from the existing electrical grid infrastructure, and while batteries are expensive, their prices have been decreasing due to technological advancements and increased production. The average total cost of an EV battery has dropped by 80% in the last decade. Additionally, government incentives and falling prices for EVs have made them more affordable for consumers.
The higher costs of HFC cars are reflected in their selling prices. For example, the Toyota Mirai and Hyundai Nexo, two of the few hydrogen cars available in the US market, start at around $50,000 and $60,000, respectively. In comparison, a growing number of EVs are becoming more affordable, with some manufacturers lowering prices on entry-level models.
While HFC cars offer quick refueling times of around 3 to 5 minutes, similar to traditional gas-powered cars, the higher costs associated with their production and infrastructure make them more expensive than EVs.

HFC cars are more complicated and prone to failure than electric cars
While hydrogen fuel cell vehicles (HFCVs) are perceived to be a good bridge between fossil fuels and full electric, they are more complicated and prone to failure than electric cars.
HFCVs use the same kind of electric motor to turn the wheels as a battery-electric car. However, it is powered by a fuel cell stack in which pure hydrogen passes through a membrane to combine with oxygen from the air, producing the electricity that turns the wheels and water vapour. The electricity generated in the fuel cell takes two routes, flowing to the electric motor and directly driving the vehicle, and/or charging a battery that acts as temporary storage until the energy is needed for driving. This "buffer" battery is significantly smaller than the battery of an all-electric car.
HFCVs are more complicated than electric cars due to the requirement of a lot of supporting systems. For instance, 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. Additionally, the thermal system (FCEV) maintains a proper operating temperature range for the fuel cell, electric motor, power electronics, and other components.
Moreover, HFCVs have fuel cells that wear out incredibly fast and are challenging to regenerate, making them more expensive. The process of creating pure hydrogen for HFCVs is also complex and energy-intensive, requiring the use of a great deal of energy to "crack" compounds like natural gas into pure hydrogen, with CO2 as a byproduct.
In contrast, electric cars draw electricity from a battery, which can be charged by plugging into a power source. This eliminates the need for the additional systems required in HFCVs, such as the power electronics controller and thermal system, making them less prone to failure.
