A fuel cell is like a battery, in that it uses a chemical reaction to create an electrical current. Unlike a battery, a fuel cell will continue to generate a current as long as the reactants are supplied. The Gemini fuel cell used liquid oxygen and liquid hydrogen to generate electricity, with water as a byproduct. Oxygen and hydrogen molecules reacted and combined across a \"proton exchange membrane,\" a thin permeable polymer sheet coated with a platinum catalyst."}, {"label": "Summary", "content": "The Gemini program pioneered the use of fuel cells in space, and this technology was subsequently used in the Apollo Service Module and the Space Shuttle Orbiter.
