Abstract
This specification discloses an electrochemical structure having two solid electrochemical cells separated by a material or region which can take up the electrochemically active species appropriate to the cells in neutral form. Combined with external circuitry, the structure can be made to exhibit transistor action and further can be made to show ac voltage, current and power gain. For example, transistor action occurs at elevated temperatures, such as at 800.degree. C., with a structure composed of two ceramic zirconium dioxide electrochemical cells separated by an enclosed volume. In normal operation, one cell, acting as an emitter, emits oxygen from an ambient atmosphere into the volume, which acts as a base region, where it is collected and returned to the ambient by the opposing cell, acting as a collector.
