They supply power to the spacecraft during missions.
so they can go out on mars and other planets
None of the Apollo spacecrafts has solar cells. All of them used fuel cells and chemical batteries to provide energy.
Fuel is so useful to spacecrafts because without the fuel the spacecraft would not go.
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.
They supply power to the spacecraft during missions.
The fuel used by the Apollo 15 spacecraft as well as all the Apollo spacecrafts , was a mixture of oxygen and nitrogen gases.

The heavier it is the stronger the engine has to be. And the stronger the engine the more fuel will it burn. And the more fuel it burns the more fuel has to be carried in the rocket. And the more fuel the rocket has to lift the stronger the engine has to be. While some Spacecrafts are not light weight such as the Apollo 11 But is the Largest And Fastest That Got to the moon
Hydrogen peroxide can be used in certain types of fuel cells called direct borohydride fuel cells. In these fuel cells, hydrogen peroxide is used as an oxidant in place of oxygen. However, the efficiency and practicality of using hydrogen peroxide in fuel cells is still being researched and developed.
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
The main element used in fuel cells is typically hydrogen, which is combined with oxygen to produce electricity through an electrochemical reaction.
Anything that needs electricity can be fed from a fuel cell.Power vehicles
