How can fuel cells be used in aerospace industries?
A. The Apollo Mission space capsules, lunar modules, and orbiters were partially powered by fuel cells. The current Space Shuttle missions receive auxiliary power from fuel cells as well. A side benefit of clean and quiet hydrogen PEM fuel cell power is the pure water produced as a byproduct, which is used by the astronauts for drinking. As metal hydride and nanotube techonology improves, better hydrogen storage will allow more and more power generation from compressed air and hydrogen with a continuous supply of drinking water.
