Which of these is a concern with respect to using fuel cell cars use of non renewable resources?
The two prime dangers from fuel cell and hydrogen-powered vehicles are the danger of electrical shock and the flammability of the fuel. Fuel cells power vehicles by electro-chemically combining hydrogen gas (H2) and oxygen (O2) from the surrounding air into water (H20) and electrical energy.
What is the main problem facing with fuel cell?
Fuel cell life cycle and value chain. 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.
Which if these is a benefit of fuel cell cars?
Fuel cell electric vehicles (FCEVs) are powered by hydrogen. They are more efficient than conventional internal combustion engine vehicles and produce no tailpipe emissions—they only emit water vapor and warm air.
What is fuel cell h2 o2 fuel cell?
In a fuel cell, hydrogen and oxygen are combined to generate electricity, heat, and water. ... The protons pass through the porous electrolyte membrane, while the electrons are forced through a circuit, generating an electric current and excess heat.
What do fuel cells use?
A fuel cell uses the chemical energy of hydrogen or other fuels to cleanly and efficiently produce electricity. If hydrogen is the fuel, the only products are electricity, water, and heat.
What is fuel cell advantages and 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.
How do fuel cells work in cars?
Like all-electric vehicles, fuel cell electric vehicles (FCEVs) use electricity to power an electric motor. In contrast to other electric vehicles, FCEVs produce electricity using a fuel cell powered by hydrogen, rather than drawing electricity from only a battery.
Are fuel cell vehicles safe?
Fuel Cell Electric cars are as safe as conventional vehicles. Toyota has spent many years testing hydrogen-powered cars in extreme conditions and temperatures to ensure they can be used safely and reliably, just like any other Toyota.
What is the main problem in using hydrogen as fuel for vehicles?
Explanation: The main problem in using hydrogen as fuel for vehicles is storage of hydrogen. Hydrogen is difficult to store because it leaks easily. Moreover, it is extremely hazardous as fuel due to its low ignition temperature and high combustion energy.
What is the major disadvantage of LPG as a fuel in the automobile?
What is the major disadvantage of LPG as a fuel in the automobile? Explanation: The major disadvantage of LPG is the reduction in the life of the engine and less power compared to gasoline. The other disadvantage of LPG is a special fuel feed system is required for liquid petroleum gas (LPG).

What are the main fuel-related issues for fuel cell safety?
- Thus, the main fuel-related issues for fuel cell safety regard the use of hydrogen. While being a very clean and energy-dense fuel, hydrogen has the tendency to disperse quickly under normal pressure. This causes the need for higher pressure of hydrogen in the fuel transport system than for natural gas.
