Electrochemical oxygen generating system

This invention relates to devices for separating oxygen from more complex gasses such as air which contains oxygen, and delivering the separated-oxygen at an elevated pressure for use immediately, or for storage and use later. More particularly, the invention relates to solid state electrochemical devices for separating oxygen from more complex gasses to produce the desired oxygen and delivering the oxygen at elevated pressures up to and exceeding 2000 psig.

A buffer zone for the prevention of metal migration

Particle migration, such as silver electro-migration, on a flat ceramic surface (14) is effectively eliminated by an upward vertical barrier formed on the surface or a groove (20) formed in the surface between two silver conductors (10), (12).
