What is the main problem of fuel cells
Cost and durability are the major challenges to fuel cell commercialization. However, hurdles vary according to the application in which the technology is employed. Size, weight, and thermal and water management are barriers to the commercialization of fuel cell technology.
What are the challenges of the fuel cells industry
As a new energy technology, fuel cells have not yet significantly penetrated the energy market. Cost, durability, and reliability are the main challenges in the commercialization of fuel cells.
What are the pros and cons of hydrogen fuel cell technology
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 are the 5 common issues of fuel system
Here are are 7 common signs that your car has a fuel system failure, according to LightHouse Automotive:The Engine is Sputtering. This often happens the faster you drive.Difficulty Starting the Car.Fuel Tank Whining Noise.Lack of Power.Loss of Gas Mileage.The Car is Surging.Fuel is Leaking.
What is the biggest problem with using hydrogen in a fuel cell
Fuel Storage
Hydrogen's energy content by volume is low. This makes storing hydrogen a challenge because it requires high pressures, low temperatures, or chemical processes to be stored compactly.

Why aren t fuel cells more popular
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.
What are the disadvantages of fuel cells
The downside of hydrogen fuel cells is the rather high cost of the materials used to produce the catalysts. In addition, the efficiency of this type of system is lower than when storing energy in batteries. The process of producing hydrogen also requires some energy input.
What is the problem with hydrogen fuel cells
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.
What are the disadvantages of fuel cell
Disadvantages: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.

What are the disadvantages of fuel system
Disadvantages of Petrol Injection System:It is important to filter the fuel carefully this may cause damages.Construction is difficult.Cost is high.It required more maintenance.It produces more sound.It may cause wear.There is an additional requirement of the nozzle, for every cylinder.

What is the problem with hydrogen technology
A key problem with the hydrogen economy is that pollution-free sources of hydrogen are unlikely to be practical and affordable for decades. Indeed, even the pollution-generating means of making hydrogen are currently too expensive and too inefficient to substitute for oil.
Which of these is a disadvantage of hydrogen fuel cells
Disadvantage: The Use of Fossil Fuels in Hydrogen Production
A common way to isolate hydrogen is to extract it from natural gas in a process called reforming. This process is costly and emits carbon dioxide, which is counterproductive to using an emission-free energy source.
What are two problems with hydrogen fuel cell vehicles
In enclosed locations with normal temperatures, spilled liquid hydrogen will create enormous gas pressures, tearing apart vessels without safety valves. The two prime dangers from fuel cell and hydrogen-powered vehicles are the danger of electrical shock and the flammability of the fuel.
What is the biggest problem with hydrogen
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.
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 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.
What are the disadvantages of hydrogen fuel cells in cars
They are complex, and expensive to build. Rumour has it that hydrogen cars cost more to make than they are sold for. Hydrogen is flammable and therefore dangerous if not properly stored or handled. Hydrogen has to be highly compressed for road use.
What is the disadvantage of hydrogen fuel
Hydrogen is a highly inflammable substance and explosive in nature; it cannot be easily transported from one place to another and it can be generated by the hydrolysis of water but it is a very expensive process.
What are the problems with the hydrogen economy
The major challenges to scaling of circular hydrogen economy include waste and cost management challenges, hydrogen transport and storage infrastructure requirements as well as environmental safety concerns.
Why are fuel cells inefficient
20 – 30% of energy is lost in the process of creating hydrogen. The hydrogen must then be compressed and stored, losing another 10%. Finally, another 30% is lost when converting the hydrogen into electricity. This leaves you with 30 – 40% of the original energy used.
What are the disadvantages of hydrogen fuel and fuel cells
The cost for a unit of power from hydrogen fuel cells is currently greater than other energy sources, including solar panels. This may change as technology advances, but currently this cost is a barrier to widespread use of hydrogen even though it is more efficient once produced.
