What are the key differences between hydrogen fuel cell vehicles and electric cars in terms of their environmental impact and efficiency?
Hydrogen fuel cell vehicles produce water as their only emission, making them cleaner than electric cars that rely on electricity generated from fossil fuels. However, the production of hydrogen can be energy-intensive. Electric cars are more efficient in terms of energy conversion and have a lower overall environmental impact if the electricity comes from renewable sources.

What are the key differences between battery and hydrogen fuel cell technologies in terms of efficiency and sustainability?
Battery technology stores energy in chemical form, while hydrogen fuel cells generate electricity through a chemical reaction between hydrogen and oxygen. In terms of efficiency, hydrogen fuel cells are generally more efficient than batteries in converting energy into electricity. However, batteries are more sustainable as they can be recharged multiple times, while hydrogen production often relies on fossil fuels.
What kind of charge would an electric dipole have on a hydrogen atom?
Hydrogen has a positive charge.
How do you separate Hydrogen from deuterium consurning extracting hydrogen from heavy water in the poles on mars?
To separate hydrogen from deuterium in heavy water (D₂O) on Mars, one can use methods such as fractional distillation or electrolysis. Fractional distillation exploits the slight differences in boiling points between D₂O and H₂O, allowing for separation based on temperature variations. Electrolysis can also be employed, where an electric current is passed through heavy water to break it down into hydrogen and oxygen, with careful control of the process to preferentially produce hydrogen. These methods can be effective in extracting hydrogen for future use in Martian exploration.
Why is the volume of gas collected twice of the volume of other gas when electric current is passed through water?
When an electric current is passed through water, water is split into it's two component gasses- hydrogen and oxygen. You will get about twice as much hydrogen as oxygen- since water (H2O) has twice the hydrogen as oxygen.
When adding electric energy to water molecules can it cause the bonds between Hydrogen and oxygen to break?
Yes, adding electric energy to water molecules can cause the bonds between hydrogen and oxygen to break through a process called electrolysis. In electrolysis, an electric current is passed through water, which results in the splitting of water molecules into hydrogen and oxygen gas. This occurs when the energy supplied is sufficient to overcome the bond energy of the H-O bonds in water.
What are the key differences between hydrogen and nuclear energy in terms of efficiency, safety, and environmental impact?
Hydrogen energy is less efficient than nuclear energy because it requires more energy to produce hydrogen. However, hydrogen is safer to handle and has lower environmental impact compared to nuclear energy, which produces radioactive waste and poses risks of accidents.
What is the differences between electric car and hydrogen fuel cell cars?
Electric cars are powered by batteries that store electrical energy, which is used to drive an electric motor. In contrast, hydrogen fuel cell cars generate electricity through a chemical reaction between hydrogen and oxygen in a fuel cell, producing only water as a byproduct. While electric cars rely on charging infrastructure and battery technology, hydrogen fuel cell vehicles require hydrogen refueling stations. Additionally, electric vehicles tend to have a higher energy efficiency compared to hydrogen fuel cell vehicles.
When was Hydrogen Electric Racing Federation created?
Hydrogen Electric Racing Federation was created in 2007.
Which is better hydrogen car or electric car?
hydrogen
Is hydrogen better or car or electric car and why?
Not because hydrogen is more expensive and there are better electric charging point networks than hydrogen worldwide.

What causes minimum environmental degradation hydrogen or coal or diesel or kerosene?
hydrogen
How do you get the Hydrogen?
Hydrogen can be obtained through various methods such as electrolysis of water, steam-methane reforming of natural gas, biomass gasification, and electrolysis of brine solutions. Each method has its own set of advantages and disadvantages in terms of cost, efficiency, and environmental impact.
Finding a Hydrogen Electric Car?
To buy the best hydrogen electric car, you should be out there and doing some research on hybrid cars. It is very important for you to find hydrogen electric cars that will save you money on gasoline. The best hydrogen electric cars can be charged at your home during the night. It is a great idea to invest in these cars and a few extra batteries for them as well.
Does hydrogen gas conduct electric electricity?
no
What kind of charge would an electric dipole have on a hydrogen atom?
Hydrogen has a positive charge.
What is the difference between a hydrogen electric and and an electric car?
Electric cars can be charged with electricity, where as hydrogen cars use a fuel cell that would have to be refilled at a refueling station. It doesn't look like there will be many hydrogen cars on the road until 2020.
