Examples

  • For the engineers responsible for making sure that the “newfangled contraption” was reliable, notably MSC’s Charles W. Matthews, head of the Gemini Project Office, the very idea of a problematic fuel cell literally produced nightmares.

    First Man

  • On their third orbit, in the middle of one of their seventeen planned experiments, Conrad noticed that the oxygen pressure in the fuel cell had dropped for some unknown reason from 800 to 70 pounds per square inch, just when “we’d released a rendezvous pod, had it on radar, and were just getting ready to intercept it—an experiment designed to provide crucial information about never-before-attempted space rendezvous.”

    First Man

  • Now he leaned up against a fuel cell of Segunian design, his rifle dangling from one hand as he flipped up his armor visor with one hand and pressed against his forehead with the other.
