Hydrogen fuel cells powered the Apollo space craft of the 1960's. They're also used today as large power plants for rural areas
the fuel cells convert hydrogen into energy using a converter and that energy is used to power the vehicle
Fuel cells primarily rely on hydrogen as their energy source. Hydrogen gas is fed into the fuel cell where it reacts with oxygen to produce electricity, heat, and water as byproducts.
More mass is converted to energy in a fusion reaction than in a chemical reaction, such as that found in a fuel cell. - APEX
The hydrogen on sugars and fats.
Carbon and hydrogen
The waste byproducts of hydrogen fuel cells are typically heat and water vapor. As the hydrogen gas is converted into electricity, the only emission produced is water, making fuel cells a clean energy source.

The waste byproducts of hydrogen fuel cells are heat and water vapor. When hydrogen is converted into electricity in a fuel cell through a chemical reaction with oxygen, these are the only emissions produced, making fuel cells a clean and efficient energy source.
Alternative energy
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! :)
