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.

What a fuel cell is why is it useful in spacecraft?

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.


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!!


Why is a fuel cell useful in spacecraft?

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


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.


What is a fuel cell and why is it important for spacecraft?

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.

How you get a space probe on My Lego network?

send capt Reynolds a space fuel cell and he'll give you a space probe blueprint


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


Why is fuel so useful in spacecrafts?

Fuel is so useful to spacecrafts because without the fuel the spacecraft would not go.


How do you make a fuel cell?

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.


How can you power the hover craft inside the top of the mill?

apparently you make something like fuel but it ain't. you fuel up the hover craft and off it goes
