Final answer:
A permanently orbiting space station would need to generate electricity. Fuel cells can be used to generate electricity by using hydrogen and oxygen.
Step-by-step explanation:
A permanently orbiting space station would need to generate electricity.
Unlike short flights of the shuttle and earlier spacecraft, which carried sufficient power in fuel cells and batteries, a permanently orbiting space station would need a continuous source of electricity. This is because it will stay in orbit for a long time and cannot rely solely on fuel cells and batteries to provide power.
One way a space station can generate electricity is by using fuel cells like the ones used in satellites, space capsules, and other vehicles. Fuel cells use hydrogen and oxygen to produce water and electricity as long as there is a continuous supply of fuel.
