Patent ID: 8445159

Claim:
A joint for a segment-in-series electrochemical device, comprising: a metal joint housing; a first electrochemical cell, comprising, a first porous electrode, a second porous electrode, separated from the first porous electrode by a solid electrolyte, and an insulating member disposed between the metal joint housing and the electrolyte and second electrode, and one or more brazes structurally and electrically connecting the first electrode to the metal joint housing and forming a gas tight seal between the first electrode and the second electrode; wherein the metal joint housing is disposed adjacent to ends of the first and second porous electrodes and the solid electrolyte of the first electrochemical cell such that it is configured for segment-in-series connection to an adjacent electrochemical cell such that ends of first and second porous electrodes and a solid electrolyte of the adjacent electrochemical cell are also adjacent the metal joint housing such that the cells are joined end-to-end.
