Abstract
The invention pertains to linear electrochemical functional elements which have strip-shaped ion-exchange membranes (IEMs) and/or hydrogen-diffusion electrodes accessible at the ends which are enclosed on all sides in an insulating manner by a jacket of a solid material. The invention describes the structure, production, and use of the functional elements in electrochemical measuring techniques. In one embodiment, a charge state indicator is created by the incorporation of a lead/lead sulfate half-cell into a lead/lead oxide cell. This coupling takes place via a linear functional element in the form of an installed ion-exchanger membrane. It makes it possible to measure three voltage values on the cell and to evaluate them in order to determine the current charge state by conventional methods.
