Abstract
This specification discloses an electrochemical structure having two separate electrochemical cells using liquid electrolytes separated by a material or region which ca 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 with a structure composed of two liquid electrochemical cells using a sulfuric acid electrolyte separated by an enclosed volume. In normal operation, one cell, acting as an emitter, emits hydrogen from a hydrogen ambient into the enclosed volume, which acts as a base region, where it is collected and returned to the ambient by the opposing cell, acting as a collector.
