ABSTRACT:
A process of manufacturing an electrochemical device including a pumping cell having a first and a second electrode, and a sensing cell having a third and fourth electrode such that the electrodes are disposed on at least one solid electrolyte body, and the second and fourth electrodes are exposed to the atmosphere in an internal cavity formed in the device. The process comprises a step of interposing an insert consisting essentially of a sublimable material in the cavity to be formed during superposition of green sheets or layers of the solid electrolyte bodies and electrodes into an unfired laminar structure, such that the insert is disposed opposite to the unfired layers of the second and fourth electrodes, and further comprises a step of co-firing the unfired laminar structure incorporating the insert so as to cause the insert to disappear through sublimation. The insert prevents portions of the solid electrolyte bodies from being extruded or displaced into the cavity while the stack of the green sheets of solid electrolyte is compressed into the unfired laminar structure.
