Hydrogen is not burned in a fuel cell. It works the same way as lithium does in an li-ion battery. However, you can use hydrogen in a combustion engine, also as a compound for energy storage. Also, "fuel storage and refueling" is a huge advantage because you don't need to worry about slow recharging. This is often seen as an advantage.

You might rather refer to a color-coded periodic table which shows which elements are gases and which are solids at room temperature. That's a much more relevant concern than whatever you're trying to say.
