Hydrogen is very abundant in our world and easy to acquire through the electrolysis of water. Hydrogen also burns clean; producing water as a byproduct. This is preferable to carbon emissions in our atmosphere.
Some industrial chemistry gives hydrogen as a by product fro example the electrolysis of brine (salt water) would give hydrogen. We can also electrolyse water to give hydrogen for fuel.
It would be simplistic to claim that hydrogen is a bad fuel, but hydrogen does present certain complications as a fuel. Because it is a gas, it is not as easy to store as a liquid fuel such as gasoline. And depending upon how it is stored, it is more likely to explode, in the event of an accident, than gasoline would be. But in some ways hydrogen is an excellent fuel. The only combustion product of burning hydrogen is water. It is completely nonpolluting. And since hydrogen can be made from water (by electrolysis) there is in principle an unlimited supply, as long as you can generate the electricity needed to perform the electrolysis.
fossil fuel may be depleted soon. but hydrogen gas can me made available. also, if there are cheaper ways to split water into hydrogen and oxygen, then the better it is as water is available everywhere ----------------------------------------------------------------- Fuel cells produce hydrogen gas from fossil fuels, and renewable fuel sources. Hydrogen can also be made from other energy (electric) sources and electrolysis of water, but compressing and transporting it poses it's own problems. Despite this, the production of hydrogen as a fuel source uses more energy than can be gained from the hydrogen itself.
Because Hydrogen is the fuel of Stars, hydrogen consumed and Helium is formed.
You probably mean a fuel cell, which is a device for combining a fuel (usually hydrogen) with an oxidizer (usually oxygen), creating electricity (and some waste heat).
Advantages are very low emissions. Disadvantage is rarity of hydrogen fuel stations.
The advantages of using hydrogen fuel cells are that they are an alternative fuel to fossil fuels, like coal, oil and gas. Also, burning or reacting hydrogen with oxygen runs electric motors and it's only emission is water vapour. The disadvantages of using hydrogen fuel cells is that hydrogen does not occur naturally on Earth and thus is not an energy source. It takes a great deal of energy to extract Hydrogen from water. Hope this helps! :)

Hydrogen can be used as fuel.
There are no commercially available hydrogen fueled cars.
Hydrogen is plentiful therefore cheep. It is also volatile if not handled properly. Comparatively, a hydrogen explosion can be close to a nuclear explosion damage wise.
Liquid hydrogen IS used as a fuel. It's used in rockets - and some cars.

It keeps me in a job !!
The most important advantage of fuel cells is that their only byproduct is water, and of course discarded parts. The disadvantage is that the hydrogen used in them has to be electrolyzed from water or found in some other way. Because of the law of conservation of energy, fuel cells do not produce energy, they only store it.

Fuel cells operate by combining hydrogen and oxygen without actual combustion as in gasoline engines. A catalyst separates the electrons and protons to combine the elements. (Some versions of fuel cells are high-temperature only.) Hydrogen gas
