Why are fuel cells not used
The fuel cell can be dangerous due to its highly flammable nature. This makes it a dangerous fuel to have in a vehicle if it crashes. Last but not the least, the price point. Let alone IC engines, Hydrogen-powered cars are significantly costlier than electric vehicles, almost twice the asking price.
Why aren t fuel cells used more
The vast majority of car companies have turned away from hydrogen because of the high density of energy consumed in its production, as well as poor funding and backing from governments, which is stopping the hydrogen revolution from expanding ever more.
Are fuel cells bad for the environment
Public Health and Environment
Emissions from gasoline and diesel vehicles—such as nitrogen oxides, hydrocarbons, and particulate matter—are a major source of this pollution. Hydrogen-powered fuel cell electric vehicles emit none of these harmful substances—only water (H2O) and warm air.
Why are fuel cells not efficient
The reason why hydrogen is inefficient is because the energy must move from wire to gas to wire in order to power a car. This is sometimes called the energy vector transition. Let's take 100 watts of electricity produced by a renewable source such as a wind turbine.
Why hydrogen fuel cells are not the future
the panels aren't free, they aren't cheap to buy and install either. Hydrogen Fuel Vehicles cannot succeed. Fuel stations are bleeding money, so there is no incentive to privately purchase infrastructure. To make them on par with ICE, you would need 120,000 in the US… will never happen from the government.
Why hydrogen fuel cells are bad
When used in a fuel cell, the only byproducts of hydrogen are heat and water vapor. Hydrogen can also be combusted, like gas,to produce electricity, which results in water vapor and nitrogen oxide (NOx), a harmful pollutant.
Are fuel cells sustainable
Hydrogen fuel cell benefits
As well as zero emissions, hydrogen is a sustainable fuel in comparison, say, to fossil fuel alternatives. It is even ecologically friendly to produce. Many hydrogen production plants run on solar or wind power and use electrolysis to extract it from water – seawater, even.
Why are hydrogen fuel cells so inefficient
The reason why hydrogen is inefficient is because the energy must be transferred from wire to gas and then back to wire in order to power a car – known as the Energy Vector Transition. As an example lets take 100 watts of electricity produced by a renewable source such as a wind turbine locally.
Why did hydrogen fuel cells fail
Low efficiency
Almost 45 percent of energy is lost to produce hydrogen during the electrolysis process in hydrogen cars which lowers their efficiency and energy conservation. Electric vehicles require an optimum amount of energy to charge onboard batteries in them.
What is a disadvantage of fuel cells
Expensive to manufacture due the high cost of catalysts (platinum) Lack of infrastructure to support the distribution of hydrogen. A lot of the currently available fuel cell technology is in the prototype stage and not yet validated. Hydrogen is expensive to produce and not widely available.
Why hydrogen fuel is not the future
Scientists and analysts say that as hydrogen molecules are much smaller and lighter than those in methane, they are harder to contain. Once hydrogen enters pipelines, it can weaken metal pipes which can lead to cracking. Hydrogen is also far more explosive than natural gas which could create safety issues.

Why hydrogen power is not the future
You'd think hydrogen would simply be made by splitting water (H2O) into hydrogen (H2) and oxygen (O), but this proves too inefficient, so about 95 percent comes from fossil fuels, mostly natural gas, a process which creates carbon monoxide and carbon dioxide and makes the first argument pointless.
What are the pros and cons of fuel cells
Hydrogen Fuel Cell Advantages and Disadvantages in MaterialHydrogen Fuel Cell Technology.Advantage: High Energy Density Improves Productivity.Disadvantage: The Use of Fossil Fuels in Hydrogen Production.Disadvantage: Hydrogen Storage and Transportation.Disadvantage: Fuel Cell Efficiency.
What are the pros and cons of fuel cell cars
Hydrogen fuel cells
Pros: No vehicle emissions other than water vapor. Fuel economy equivalent to about twice that of gasoline vehicles. Hydrogen is abundant, and can be made from renewable energy. Cons: This space-age technology is expensive.
What is wrong with hydrogen fuel
While not as bad as using electricity generated using fossil fuels, the process still releases huge amounts of carbon – each tonne of hydrogen produced releases eleven tonnes of CO2, equivalent to driving 72,000 km in a passenger car.
What are the limitations of fuel cells
Limitations of Fuel Cells
Gaseous fuel is tough to handle. The fuel gas (hydrogen, oxygen, etc.) must be held as a liquid in a specifically built cylinder at a very low temperature and high pressure. This rise is due to the increased cost of the cell, which comes with a number of practical issues.
Why are we not using hydrogen energy
Currently, most hydrogen is produced using coal or natural gas as feedstocks. Both emit harmful by-products into the atmosphere, including carbon dioxide. So, while hydrogen itself is eco-friendly the processes used to isolate the chemical element have a significant environmental footprint.

What are the disadvantages of biofuel cells
Disadvantages Of Biofuel:It disturbs the life cycle.Cost of labour and it requires huge space for storage.More water consumption, especially in dry climates.Growing biomass for biofuel production increases the demand for agricultural land.
What are the disadvantages of fuel cars
One of the main cons of owning a traditional gasoline-powered car is the environmental impact. Gasoline cars produce emissions that contribute to air pollution and climate change. This can have a negative impact on the health of both individuals and the planet as a whole.
What are 3 cons of hydrogen fuel
Hydrogen fuel cells
Cons: This space-age technology is expensive. Acceptable range requires extremely-high-pressure, on-board hydrogen storage. Few places to refuel. Hydrogen is very expensive to transport and there is no infrastructure in place yet.
What is the challenge of fuel cell
Fuel cells have undoubtedly the potential to meet the high-power density demand, but the current challenge lies in reducing the size of hydrogen storage systems to meet the market demand of upcoming portable electric devices.
Why are hydrogen fuel cells bad
Cost of Raw Materials. Precious metals such as platinum and iridium are typically required as catalysts in fuel cells and some types of water electrolyser, which means that the initial cost of fuel cells (and electrolysers) can be high. This high cost has deterred some from investing in hydrogen fuel cell technology.
