Its the source of energy.
'and it can even be used to generate electricity for spacecraft.'
From Pearson Education Limited 2002
it holds the fuel
Without fuel, the spacecraft cannot launch.
it lifts up the 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
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!!
because hydrogen is in the fuel cell. hydrogen is useful in many things including spacecrafts. please do not use this for anything important because I'm not sure but i been reading this page about hydrogen and it is true. I know for sure that hydrogen is used for rocket fuel because it is on the sheet. By Georgina thank you 4 going on wikianswers.com
It stores fuel.
The answer, is that there are only two types of rockets which fuel modern spacecraft. they are solid fuel rockets, and liquid fuel rockets
Fuel, food, and hopefully, people.
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
