House power for our moon men will come from an efficient new fuel cell developed by Pratt & Whitney Aircraft for the National Aeronautics and Space Administration's Manned Spacecraft Center. The fuel cell will generate life-sustaining electrical power during the Apollo spacecraft's round-trip voyage to the moon. Pratt & Whitney Aircraft provides design and manufacturing leadership in power for many applications, in and out of this world.
