Fuel cell cars, also known as hydrogen cars, are a type of electric vehicle that uses hydrogen fuel cells to generate electricity for an electric motor. These cars are considered more environmentally friendly than traditional internal combustion engines as they produce zero carbon emissions. In addition to their ecological benefits, fuel cell cars also offer a quieter driving experience compared to conventional cars. While the noise level inside a fuel cell car is similar to that of a traditional car, measurements indicate a slight increase in noise outside the vehicle when compared to a gasoline-powered car. This increase is attributed to hydrogen's higher reactivity, resulting in a unique, almost otherworldly sound. Despite this slight difference, fuel cell cars contribute significantly to reducing noise pollution.

What You'll Learn
Fuel cell cars are quieter than combustion engines
The noise produced by a car is an important factor in the overall driving experience. While some people may prefer a louder engine sound, others may opt for a quieter ride. When it comes to fuel cell cars, also known as hydrogen fuel cell cars, they are indeed quieter than traditional combustion engines.
Fuel cell cars are electric cars that are powered by hydrogen fuel cells. These vehicles generate electricity using a fuel cell, which then powers the electric motor. This process is much quieter than the thousands of tiny explosions that occur in a combustion engine, resulting in a more peaceful driving experience.
The unique sound of a fuel cell car can be described as otherworldly or alien. While it may not be as loud as a traditional engine, it still produces a distinct noise that sets it apart from other vehicles. This sound is particularly noticeable when the car whooshes past, adding an element of intrigue to the driving experience.
One study found that hydrogen fuel produced slightly higher noise levels outside the vehicle compared to gasoline. However, the difference was minimal and may not be noticeable to the human ear. Additionally, the noise generated by fuel cell cars is not from the engine but from other components, such as the compressor or pumps.
Overall, fuel cell cars offer a quieter and more environmentally friendly option for drivers. With their efficient power plants and reduced emissions, these vehicles provide a sustainable alternative to traditional combustion engines, making them an appealing choice for those seeking a quieter and greener ride.

Hydrogen fuel cells are more expensive than petrol or diesel
Hydrogen fuel cell cars are known to be quieter than vehicles powered by internal combustion engines, which produce powertrain noise from thousands of tiny explosions. Electric cars are known to be quiet, with a slight whine, while hydrogen fuel cell cars add a different, almost otherworldly, auditory experience.
While hydrogen fuel cell technology has many advantages, such as being a non-toxic fuel source with zero emissions, it is currently more expensive than petrol or diesel. The cost of hydrogen fuel is expected to decrease in the future as production increases and more efficient methods of production are developed. However, as of now, hydrogen fuel cells are generally more expensive for consumers.
The current cost of a kilogram of hydrogen is around 14 euros, and a fuel cell car can travel approximately 100 kilometers on one kilogram of hydrogen. This makes the cost per kilometer of a hydrogen car comparable to that of combustion vehicles. However, the limited availability of hydrogen-powered vehicles and the higher prices of these cars contribute to the overall higher cost of hydrogen fuel cell technology.
The average prices of hydrogen-powered cars from Toyota and Hyundai range from £55,000 to £67,000. In contrast, traditional fossil fuels like petrol and diesel have lower upfront costs for vehicles, and the fuels themselves are currently more affordable. However, it is important to note that the prices of petrol and diesel are expected to rise due to decarbonization commitments and reduced production levels.
In conclusion, while hydrogen fuel cell technology has promising environmental benefits, the higher costs of the vehicles and fuel make it more expensive than petrol or diesel options in the short term. However, with expected advancements and increased production, hydrogen fuel cells may become more cost-competitive in the future.

Hydrogen fuel cells are safer than combustion engines
Hydrogen fuel cells also have numerous safety features in place. Hydrogen fuel cells do not rely on combustion, instead, they use a safe chemical transfer without burning fuel. Hydrogen is non-toxic and non-poisonous to humans, making it safer to work with than fossil fuels. Additionally, hydrogen is lighter than air, which means it dissipates quickly, aiding in rapid and safe dispersal in the event of a leak.
The hydrogen in fuel cell cars is stored in gaseous form in thick-walled tanks, which have been proven safe through numerous crash tests. These tanks remain undamaged and no hydrogen leaks have been reported. Hydrogen technology is not new, it has been tried and tested in various areas, and its use is expected to increase in the transport and infrastructure industries.
The use of hydrogen fuel cells in cars can also make them quieter than traditional combustion engines. Electric cars are known to be quiet, with a slight whine, while hydrogen fuel-cell cars add an otherworldly audio element to the driving experience. This lack of engine noise can be a safety concern, as it may pose a risk to pedestrians, but this is often counteracted by simulated engine sounds.

Hydrogen fuel cells are more sustainable than combustion engines
Hydrogen fuel cell cars are known to make a distinct noise, described as "otherworldly" by some. These cars are powered by an electric motor and are classified as e-cars. They are different from battery-powered electric cars as they produce electricity themselves. Hydrogen fuel cells convert chemical energy directly into electrical energy, making them more efficient than traditional internal combustion engines.
Hydrogen fuel cells are a more sustainable alternative to combustion engines. Unlike traditional engines, which run on fossil fuels and emit greenhouse gases and pollutants, hydrogen fuel cells emit only water vapour and warm air. This makes them ideal for sectors where direct electrification is challenging, such as heavy industry and long-haul transport. Additionally, hydrogen fuel cells can store surplus renewable energy and release it when needed, facilitating a shift towards more sustainable energy systems.
The use of hydrogen fuel cells can also help strengthen national energy security and conserve petroleum resources. Hydrogen can be produced from a variety of domestic resources, including natural gas, coal, solar energy, wind, and biomass, with the potential for near-zero greenhouse gas emissions. This diversity of production methods enhances the resilience of the transportation energy system.
However, the sustainability of hydrogen fuel cells depends on certain factors. Firstly, it relies on using renewable energies in hydrogen production and expanding the technical infrastructure to shorten transport routes. Secondly, the availability of hydrogen generation and refueling infrastructure is crucial for its widespread adoption. To achieve this, investments in production, storage, and distribution infrastructure are necessary. Lastly, the cost of fuel cells needs to become more competitive without compromising performance. With these considerations in mind, hydrogen fuel cells have the potential to power a more sustainable future.

Hydrogen fuel cells are not widely available
Hydrogen fuel cell cars are quiet during operation as they have few moving parts. They produce a different, almost otherworldly sound compared to vehicles powered by internal combustion engines. However, hydrogen fuel cell technology is not yet widely available due to several factors.
Firstly, the availability of hydrogen fuel itself is a challenge. For example, despite plans for California to have 100 hydrogen fuel stations, the current number is less than 60, and this number is not growing significantly. The closure of hydrogen stations, such as Shell's recent shuttering of its seven stations in California, further exacerbates the issue. The limited availability of hydrogen fueling infrastructure can deter potential consumers from adopting hydrogen fuel cell vehicles.
Another critical barrier to the widespread adoption of hydrogen fuel cells is the cost of energy generated by these cells. Hydrogen fuel cells were more expensive than batteries or petrol as of 2020, primarily due to the costs associated with manufacturing the cells. Platinum, for instance, is one of the most costly components of a direct hydrogen-fueled polymer electrolyte membrane fuel cell. While technological advancements have driven down prices, with a roughly 60% drop in prices from 2006 to 2018, further reductions in cost are necessary to make hydrogen fuel cells competitive on the market.
The production of hydrogen fuel cells also faces challenges. Electricity is a major component of the cost of green hydrogen, and the efficiency of electrolysers in producing green hydrogen impacts the overall cost. Technological advancements, such as the ultra-efficient electrolyser developed by Hysata, aim to address this issue by boosting efficiency and lowering costs. Government support for green hydrogen production, as seen in Tasmania, Australia, can also encourage the wider use of hydrogen fuel cells.
While hydrogen fuel cell vehicles offer ecological benefits, such as reduced emissions and clean energy transport options, the limited availability of hydrogen fuel, the high cost of energy generated by fuel cells, and the challenges in production currently restrict their widespread adoption. However, ongoing innovations and increasing government support indicate a potential shift towards more widespread use in the future.
