Abstract:
1. A solid state electrochemical device, comprising: an electrically conductive housing member; at least one unit in electrical contact with said conductive housing member, said unit comprising a first electrochemical cell and a second electrochemical cell, each electrochemical cell comprising a laminate of a first fuel electrode and a second air electrode, separated by a planar, solid state electrolyte, said air electrode having a current collector attached thereto, the current collector of at least one of said air electrodes connected to said electrically conductive housing member, the first and second electrochemical cells having a first end and a second end, and sealed to one another by a seal at their first and second ends, the seal at the first end electrically conductive, the seal at the second end electrically insulating, and wherein each electrochemical cell is positioned adjacent to one another such that electrodes of one type are facing inward toward one another and the electrodes of the other type are each facing outward, the inwardly spaced electrodes positioned so as to define a space there between sufficient for passage of a gas during operation of the device.
