What You'll Learn
Hydrogen fuel cell vehicles are zero-emission vehicles
Hydrogen fuel cell vehicles (HFCVs) are electric vehicles that don't need plugs. They are zero-emission vehicles that emit only water vapour. HFCVs are commonly compared with electric cars, but they have some pros and cons that make them different from the typical battery-powered EV.
The most common type of fuel cell for vehicle applications is the polymer electrolyte membrane (PEM) fuel cell. In a PEM fuel cell, an electrolyte membrane is sandwiched between a positive electrode (cathode) and a negative electrode (anode). Hydrogen is introduced to the anode, and oxygen (from the air) is introduced to the cathode. The hydrogen molecules break apart into protons and electrons due to an electrochemical reaction aided by a catalyst. The electrons then travel through an external circuit to power the electric motor.
HFCVs can be refuelled quickly and have a range of around 250 to 300 miles, which is in line with the average gasoline-powered car and is a range that few electric cars can match. They also offer seamless power and instant torque from their electric motors, with very little sound.
However, HFCVs are still exceedingly rare. In the US, only around 17,000 hydrogen-powered vehicles are on the roads, and they are all in California, the only state with a network of retail hydrogen fuelling stations. Creating a brand-new fuelling network from scratch has been expensive and unreliable, and the fuel is much pricier than gasoline or electricity.

Hydrogen fuel cell vehicles are quick to refuel
Hydrogen fuel cell vehicles (HFCVs) are quick to refuel, taking approximately five minutes to fill up, which is comparable to the refueling time of standard gasoline vehicles. This rapid refueling capability is a significant advantage of HFCVs over electric vehicles (EVs), which often require lengthy charging times. The quick refueling of HFCVs is made possible by their use of hydrogen as an energy carrier, which allows for seamless refueling at specialized hydrogen fueling stations.
HFCVs, such as those offered by Toyota, Honda, and Hyundai, utilize a fuel-cell stack that combines pure hydrogen with oxygen from the air to generate electricity and power the vehicle. This process produces only water vapor as a byproduct, making HFCVs environmentally friendly with zero toxic emissions. The refueling process for HFCVs involves filling high-pressure carbon-fiber tanks with hydrogen at these dedicated hydrogen fueling stations.
While the refueling time for HFCVs is comparable to that of conventional vehicles, the availability of hydrogen fuel stations remains a challenge. The development of a robust network of hydrogen fueling stations is crucial to support the widespread adoption of HFCVs. In California, for example, there are efforts to increase the number of hydrogen fueling stations to meet the growing demand for alternative fuel options.
The integration of hydrogen vehicles into citizen-oriented energy communities offers an opportunity to enhance energy resilience and sustainability. With their rapid refueling capabilities and zero-emission profiles, HFCVs play a pivotal role in advancing cleaner transportation solutions. However, uncertainties in driving patterns and refueling behaviors pose challenges to their seamless integration, requiring innovative solutions to address these uncertainties.
Overall, the quick refueling of HFCVs is a significant advantage, offering convenience and efficiency comparable to gasoline vehicles while also providing the environmental benefits of electric vehicles.

Hydrogen fuel cell vehicles are rare
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 it difficult for manufacturers to sell them in volume, and the high prices have deterred some consumers. Additionally, the lack of hydrogen fueling infrastructure has been a significant barrier to the widespread adoption of these vehicles. The number of hydrogen fueling stations is limited, and the process of refueling can be more complicated and time-consuming than with traditional gasoline or electric vehicles.
Another factor contributing to the rarity of hydrogen fuel cell vehicles is the competition from battery-electric vehicles (BEVs). BEVs have seen rapid advancements in technology and infrastructure, making them a more attractive option for consumers. The rise of BEVs has reduced the demand for hydrogen fuel cell vehicles, as consumers now have more choices within the electric vehicle market.
Despite their rarity, hydrogen fuel cell vehicles offer several advantages over traditional gasoline and electric cars. They offer a long range of 250 to 300 miles on average, which is comparable to gasoline-powered cars and exceeds the range of many electric vehicles. Hydrogen fuel cell vehicles also have quick refueling times, taking only around five minutes, similar to refueling at a gas station. Additionally, they produce zero toxic vehicle emissions, emitting only water vapor, making them environmentally friendly.
While hydrogen fuel cell vehicles are currently rare, there is potential for growth in the market. California, for example, expects to have 1 million hydrogen fuel cell vehicles on its roads by 2030, supported by 1,000 hydrogen fueling stations. Additionally, advancements in technology, such as the development of new catalysts that reduce the cost of fuel cells, may make these vehicles more accessible and affordable in the future.

Hydrogen fuel cell vehicles are expensive
The vehicles themselves are also costly to manufacture. In 2015, the two mainstream hydrogen cars on sale in the US, the Toyota Mirai and Hyundai Nexo, started at around $50,000 and $60,000, respectively. While Hyundai has since cut the cost of building its fuel cell electric vehicles by 70%, the high price of the vehicles remains a barrier to their expansion and accessibility.
The limited infrastructure for hydrogen refueling is another factor contributing to the expense of hydrogen fuel cell vehicles. The rollout of new infrastructure is inherently difficult, and the lack of sufficient refueling stations limits the number of hydrogen fuel cell vehicles that can be supported. This issue is not unique to hydrogen fuel cell vehicles, as it also hindered the adoption of CNG cars despite their cheaper fuel costs.
The benefits of hydrogen fuel cell vehicles include their long range, quick refueling times, and zero toxic vehicle emissions. However, the high costs of the vehicles and fuel, as well as the limited refueling infrastructure, currently make them less accessible and convenient than gasoline or electric vehicles for most consumers.

Hydrogen fuel cell vehicles are the future
One of the biggest advantages of hydrogen fuel cell vehicles is their range and quick refuelling time. With a range of 250 to 300 miles, they offer a similar range to gasoline-powered cars, while also providing the environmental benefits and low operating expenses of an electric car. The refuelling process for hydrogen fuel cell vehicles is also much quicker than that of electric cars, taking only around five minutes, which is comparable to refuelling a gasoline car.
While sales of hydrogen fuel cell vehicles have been low, with only around 17,000 on US roads as of mid-2022, the industry is expected to grow. California, which is considered the most welcoming market for these vehicles, expects to have 1 million hydrogen fuel cell vehicles on its roads by 2030, supported by 1,000 hydrogen fuelling stations. Automakers such as Hyundai and Toyota have also been working to make these vehicles more affordable, with Hyundai cutting the cost of building its fuel cell electric vehicle by 70% over the past decade.
In conclusion, hydrogen fuel cell vehicles offer a unique driving experience with seamless power and instant torque from their electric motors, all while producing zero toxic vehicle emissions. With improvements in infrastructure and a decrease in costs, hydrogen fuel cell vehicles are poised to become a more common sight on our roads in the future.
