    • 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.

    • A process which comprises thermally decomposing in an electrically heated vibrating helical conveyor, manganese carbonate (MnCO.sub.3 x H.sub.2 O) into a manganese oxide (predominantly of Mn.sub.2 O.sub.3 x Mn.sub.5 O.sub.8) catalyst at about 500.degree. C., and processing this catalyst into a highly active electrode paste by dry intensive mixing with a carbon-containing conductive material (carbon black, graphite or activated carbon) and PTFE as the binder. The resulting electrode paste can be rolled into a supporting net made from Ni or Ag. Also a two-step mixing process in which the catalyst powder is first premixed with small amounts of a conductive agent and a binder, compacted and granulated, and then combined with the larger residual amount of the intended amounts of conductive agent and binder in a second mixing step. The finished gas diffusion electrode has a biporous structure consisting of hydrophilic and hydrophobic pore canals, which is highly favorable for the transport processes and the electrochemical reaction. The electrode is useful in fuel cells, alkali chloride electrolyzers and air cells.

    • A manufacturing process for nickel (II) hydroxide suitable as active positive electrode material in alkaline electrochemical cells transforms solid Ni(NO.sub.3).sub.2 directly into Ni(OH).sub.2 using sodium hydroxide and with the least possible homogeneous solute phase of Ni.sup.2+ ions. Ni(NO.sub.3).sub.2 is deposited on the lower end of a diagonally upward moving conveyor belt, to which concentrated NaOH is supplied from the opposite direction. The depressions in the conveyor belt, which prevent downward sliding of the reaction product, discharge at the upper end Ni(OH).sub.2, together with easily separable NaNO.sub.3. At the lower end, the used NaOH is discharged. It can be reconcentrated, after separation of entrained NaNO.sub.3, in a vacuum evaporator and reused. The intermediate products of the process are basic nickel nitrates, for example of the composition Ni(NO.sub.3).sub.2 .times.Ni(OH).sub.2 .times.6H.sub.2 O.
