I heard its from fuel cells? Even heard that the astronauts carry enough water for themselves? Please and thanks guys
The fuel cells on the shuttle created electricity by regulating the reaction where oxygen and hydrogen combine. This reaction produces both energy (electrical in the case of a fuel cell) and water. The water could be collected and used. Production of water could be up to 11kg of water per hour. abyss.uoregon.edu/~js/space/lectu spaceflight.nasa /shuttle/refe
They don't bring a whole lot with them, actually. It is very expensive to bring too much. Most of their water is recycled while they are out there. Their urine, their sweat, everything. There's a filtration system on the shuttle that recycles all of the moisture that they emit. -------------------------- I don't get the thumbs-down. Somebody show me where I'm wrong, because I've listened to interviews of NASA employees and astronauts who have explained the same thing. If I'm incorrect, I apologize, but I've heard this several times.
To generate electricity the space shuttle used fuel cells. These were essentially the reverse of the classic electrolysis we've all done in school. When you put an electric current through water you get gas bubbles forming at the electrodes: one is oxygen, the other hydrogen, formed from the splitting of water. In a fuel cell this process is reversed. Hydrogen and oxygen are combined and this generates an electrical current and water is the byproduct. When they developed the fuel cells on the arly Gemini and Apollo flights in the 1960s they found that the fuel cells generated so much water that they had enough to drink, enough to run the cooling system of the electronic systems and they still had some left over.
It doesn't. It hasn't flown for over a year.
