Patent ID: 7270908

Claim:
An electrochemical cell stack, comprising: a first endplate, said first endplate comprising a fluid passage for a water feed, a fluid passage for an oxygen output, and a fluid passage for a hydrogen output; a second endplate; an electrochemical cell disposed between a first separator and a second separator, said electrochemical cell including a first electrode in electrical communication with said first separator, a second electrode in electrical communication with said second separator, and a membrane layer between said first electrode and said second electrode, said first electrode being in fluid communication with said fluid passage for said water feed and said fluid passage for said oxygen output, and said second electrode being in fluid communication with said fluid passage for said hydrogen output; a first conductor being accessible through said first endplate, said first conductor being in electrical communication with said first separator; and a second conductor being accessible through said second endplate, said second conductor being in electrical communication with said second separator.
