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 else can I help you with?
Why is fuel cells so useful in space craft?
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 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 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!!
Why is fuel cells useful in spacecrafts?
so they can go out on mars and other planets
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 do spacecrafts use fuel cells?
Spacecraft use fuel cells because they are lightweight, efficient, and reliable sources of power. Fuel cells can generate electricity by combining hydrogen and oxygen, producing water as a byproduct, making them a clean energy solution for space missions. Additionally, fuel cells can provide continuous power for long-duration missions in space.
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 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
What is a fuel cell and why is it so useful on a spaceship?
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.
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.
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
