It is emission free because it only produces water
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! :)

Red, blue, green, and violet are found in the emission spectrum of hydrogen.
Niels Bohr studied the emission lines of Hydrogen.
You can't, with just the CO2 emission figure.
The emission output at tail pipe can be used to check causes of little air or too much fuel. The emission output can check the levels of water vapor, sulfur dioxide, hydrogen and particulate carbon soot.
Hydrogen is burnt to boil water. The steam spins the electric generators, as in a fossil fuel (coal, oil and natural gas) power station, except without causing global warming, as the only emission is water.

Niels Bohr in 1913.
Only if Fusion becomes a reality. Since "free" hydrogen is not available it must be "made" (separated from water, etc.). Thus it can "transport" energy, but it can't be a fuel (or energy) source.
Normaly it is called a part of the fuel system.
