Yes, the only byproduct of hydrogen is water.
The only byproduct of using pure hydrogen as a fuel is water, often in vapor form.
Peroxisome produce hydrogen peroxide (H2O2) as a byproduct of their metabolic processes.
The only byproduct of an oxygen and hydrogen fuel cell is water. There are other less common types of fuel cells, such as zinc and air cells, which do produce other byproducts.
Hydrogen is very flammable and can easily explode. Look back the Hindenburg blimp that used hydrogen. Hydrogen burns very cleanly leaving just water vapor of a byproduct. Using Hydrogen as a fuel for cars sounds great except that you need to make it by splitting water into Hydrogen and Oxygen. That uses up as much energy as the burning of Hydrogen releases. In use as a fuel for cars, you can imagine the explosion when a hydrogen tank bursts and ignites.
most permanent hair dyes, the human body makes peroxide as byproduct for some cellular processes
Its byproduct is water.

Water is the benefit of a hydrogen fuel cell ;)

Water.
You don't. Sea water is the combustion byproduct of hydrogen. That is, water is water you get when you burn hydrogen.
The success of the hydrogen car is because the the hydrogen fuel cell. This cell converts hydrogen into electricity and powers the car and the only byproduct is heat and water.
A fuel cells uses hydrogen and oxygen to make electricity, and produces water as a byproduct.

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.
