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.
A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction. It is useful in spacecraft because it provides a reliable and efficient way to generate power in space without the need for combustion. Fuel cells have high energy density, are lightweight, and produce clean electricity, making them ideal for use in space where reliability and efficiency are crucial.
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
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.
A fuel cell is an electrochemical device that converts chemical energy into electrical energy. It is important for spacecraft because it provides a reliable and efficient power source for long-duration missions in space. Fuel cells can generate electricity using hydrogen and oxygen as fuel, producing water as a byproduct, which is crucial for life support systems on spacecraft.

because they are used to provide water and electricity for the spaceship... so very useful....
There was not enough fuel in the space craft to land.
Without fuel, the spacecraft cannot launch.
it lifts up the spacecraft

send capt Reynolds a space fuel cell and he'll give you a space probe blueprint
A fuel cell is an electrochemical device that converts the chemical energy of a fuel, typically hydrogen, and an oxidant, often oxygen, into electricity, water, and heat through a reaction. In a spaceship, fuel cells are highly useful because they provide a reliable source of power while producing minimal waste, primarily just water, which can be recycled for drinking and other uses. Additionally, fuel cells operate quietly and efficiently, making them ideal for the constrained environment of space missions. Their lightweight and compact design also contribute to their effectiveness in spacecraft applications.
To find the fuel cell in Poptropica's Astronight Island, head to the space station area. Look for a door that leads to the interior of the station, and navigate through the rooms until you reach the area with the fuel cell. Interact with the fuel cell to collect it, which is necessary for completing the island's mission. Be sure to explore thoroughly, as some areas may require solving puzzles or overcoming obstacles to access the fuel cell.
Hydrogen fuel cells powered the Apollo space craft of the 1960's. They're also used today as large power plants for rural areas
This is a specialised topic and there are a variety of different types possible, only time and experience wil show which type is the most useful. My best advice is to read the Wikipedia entry 'Fuel Cell', which covers the ground pretty thoroughly.
