Fuel cells produce energy from hydrogen by?
the fuel cells convert hydrogen into energy using a converter and that energy is used to power the vehicle
What is the external fuel of choice used by cells as a ready source of energy?
Cells do not choose their source of energy.
Where does the energy that moves a car come from?
From fuel used in car
Did Apollo 11 have solar cells?
None of the Apollo spacecrafts has solar cells. All of them used fuel cells and chemical batteries to provide energy.
What are advantages of fuel cells?
The most important advantage of fuel cells is that their only byproduct is water, and of course discarded parts. The disadvantage is that the hydrogen used in them has to be electrolyzed from water or found in some other way. Because of the law of conservation of energy, fuel cells do not produce energy, they only store it.

Why are fuel cells used on the space shuttle instead of batteries?
Two reasons:Weight. Batteries are heavier per energy unit than fuel cells.Capacity. Fuel cells can store much more energy than batteries.As a bonus, the weight for the fuel cell fuel reduces the weight of another required consumable: water. The "exhaust" of fuel cells is pure water which astronauts can drink.
Has hydrogen fuel cells been used as energy yet?
Hydrogen fuel cells powered the Apollo space craft of the 1960's. They're also used today as large power plants for rural areas
What major fuel is used for the cell's activities in the human body?
Cells primarily use carbohydrates, especially glucose, which is broken down during cellular respiration, forming molecules of ATP, which are used by the cells in order to get energy to do work (cellular activities). Cells get energy from ATP molecules when they are broken down into ADP and P, which releases energy.
What is the fuel used in a fuel-cell automobile?
Fuel cells come in many varieties. Low-temperature designs such as proton exchange membrane fuel cells [PEMFC's, also known as polymer electrolyte membrane fuel cells] are mostly aimed at portable and transport applications
Hydrogen fuel cells combine hydrogen and oxygen to produce water and energy Assume 1 kg of fuel is used and the mass of the water produced is 1.10 x 10-11 kg How much energy is produced by this fuel?
do the math
Are fuel cells a renewable or non renewable source of energy?
Fuel cells are a manufactured item and are not renewable. The fuel that is used in the fuel cells can either be renewable (alcohol, methane from waste digestion,hydrogen from wind or solar conversion of water) or non-renewable (Hydrogen or methane from oil and gas production, alcohol from industrial processes)
