hydrogen is highly explosive.

What are some advantages and disadvantages of hydrogen fuel cells?

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! :)

Which energy has no disadvantages?

There are no energy sources without disadvantages.

What are the disadvantages about hydrogen?

What are some disadvantages of hydrogen energy?

Hydrogen Energy is currently more expensive than any other fuel source, there is also no existing infrastructure to accommodate a Hydrogen fuel cell. The process for extracting Hydrogen to be used also usually requires the use of burning fossil fuels, thus creating pollution. Then there is the fact Hydrogen is both hard to store and distribute.

Why is hydrogen an excellent energy source?

It isn't - there are no large deposits of hydrogen anywhere. Hydrogen can be used for energy STORAGE.

How is hydrogen an alterative energy source?

Since there are no significant amounts of free hydrogen, it should be considered more of an energy storage than an energy source. In other words, it takes energy to separate water into hydrogen and oxygen; you get that energy back when the hydrogen is burned.
