because they are used to provide water and electricity for the spaceship... so very useful....

What a fuel cell is why is it useful in spacecraft?
a fuel cell is a cell that produces electricity they are used to provied power and water for the spacecraft so the space craft could'nt really survive with out fuel cells
Why is a fuel cell so useful in space craft?
Because a fuel cell converts the chemical energy of a fuel and an oxidant into electricity. This means that the space craft uses this electricity to work. It is basically like a giant battery which powers the space craft. Hope this answers your question.
Why is a fuel cell so useful in spacecraft?
they are used to provied power and water for the spacecraft so the space craft could'nt really survive with out fuel cells Because fuel cells do actually fart it's well documented. And they do a poo when they get tired! < SOOO TRUE!!
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
How did SMART-1crash?
There was not enough fuel in the space craft to land.
How could fuel cells give space crews electricity and water?
fuel cells converts chemical energy to eletrical power and the only waste product for fuel cells is water
Why is fuel cells useful in spacecrafts?
so they can go out on mars and other planets
Why are fuel cells useful in space?
spacecraft need electrical power and clean water (for humans and for cooling) fuel cells efficiently produce electrical power and clean water from oxygen and hydrogen, saving the need to carry extra water which is quite heavy and costly to lift into space The Gemini and Apollo spacecraft used fuel cells for power and water. however, fuel cell complexity and the ever lowering cost and improved efficiency of solar panels has led to a decline in their use no new spacecraft uses them
What battery does NASA use for their space shuttles?
They get electricity through the use of fuel cells. not batteries. The current limiter to the length of a mission is the amount of hydrogen and oxygen carried to use in the fuel cells.
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.
Why does space probe need very little fuel?
In space there is no friction, so once the space craft gets moving it will stay in motion until it runs into something. The lack or resistance (friction) means it doesn't have to keep pushing to continue moving. It only needs enough fuel to get it up to speed then it will continue on by itself.
Why is fuel so useful in spacecrafts?
Fuel is so useful to spacecrafts because without the fuel the spacecraft would not go.
