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
because they are used to provide water and electricity for the spaceship... so very useful....
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!!
fuel cells converts chemical energy to eletrical power and the only waste product for fuel cells is water
so they can go out on mars and other planets
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.
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.
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.
Hydrogen fuel cells powered the Apollo space craft of the 1960's. They're also used today as large power plants for rural areas
Yes. Fuel cells could viably power the entire car. For evidence, look at NASA's space shuttles. All are totally powered by fuel cells. Fuel cells have even been developed to power, heat, and provide pure drinking water for homes. They're currently expensive, but with increased demand, the price would natural come down.
Fuel is so useful to spacecrafts because without the fuel the spacecraft would not go.
yes extremely useful as they are the cells that defend the body from infection
