Hydrogren
because water is not a fuel but it is a byproduct of burning of hydrogen. while petrol is itself is fuel.
When hydrogen is burned the product is pure water vapor. Here is the equation: 2H2 + O2 = 2H2O
sugar
coal
when an excess of oxygen is used CO2 and water (in the form of steam) is produced but if a quantity too small for the reaction is used CO is produced and again water (in the form of steam!) i hope this helps :)
Hydrogen is the only fuel that forms exclusively water when burned. Other fuels will form water in addition to other by-products such as carbon dioxide.
Its byproduct is water.
The only byproduct of using pure hydrogen as a fuel is water, often in vapor form.
Water.
Water is the benefit of a hydrogen fuel cell ;)
I think it is water pretty sure it is water :)
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.

Water.
Water vapor is the sole byproduct of fuel cell electric vehicles.
Water vapor is the sole byproduct of fuel cell electric vehicles.
water which is an electrolyte in this case , or hydrogen in the water is used and burned
