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!!
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
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.
It depends on the size of the vessel and the kind of propulsion used... so I can't really give an answer. On a side note 90-95% of a spacecraft's fuel is used to break earth's gravity, once in space it takes very little fuel to move a large distance.
By using the law of action and reaction. The rockets that launch spacecraft expel huge amounts of hot gas from burning fuel out of their exhausts, and this pushes the rocket (vehicle) upward in a rapid acceleration. This is necessary to overcome the force of gravity that pulls down on everyone and everything on the Earth. When the spacecraft is moving fast enough (escape velocity), it is able to enter an orbit around the Earth. From orbit, spacecraft can use smaller rockets to leave Earth entirely, and travel to the Moon or to other planets. The limit to this is that you need to use lots of energy to get to space, and even more to go anywhere else. All of the fuel has to lift its own weight as well as the craft (payload), so this takes very large rockets and huge amounts of fuel.
Mars.!!! However, spacecraft have landed on Venus, but the atmosphere on Venus is such that spacecraft are crushed/collpase. So no exploration has been done on Venus.
Without fuel, the spacecraft cannot launch.

Fuel is so useful to spacecrafts because without the fuel the spacecraft would not go.
They supply power to the spacecraft during missions.
because it is to do with other planets but mostly mars and galexy if we had the tehcnical difficultys in the balance of time, timeloards from doctor who would come back to life if we belived.
The larger and heavier something is, the harder it is to get into space. The more weight you put into a spacecraft, the more fuel you need. And on top of that, you need additional fuel to get that fuel into space, so the need for fuel increases exponentially with the weight of the spacecraft.

A fuel cell is different from a battery cell in so far as reactants are constantly supplied to a fuel cell making it an open system whereas a battery cell is a closed system that stores the reactants within it. A fuel cell works as long as fuel is supplied to it whereas a battery cell requires regular replacements.
