  • Solid proton conductors and their use
    Patent number: 4495078
    Abstract: Solid proton conductors are described, which are based on zeolites having oton-containing cations and having six-member and larger rings as secondary structural groups of the zeolitic structure, and in whose crystal lattice passages a phase is present which promotes proton transport. Their use as separator material and electrolyte for electrochemical cells is also described.

  • Process for the production of thermodynamically stable solid ion conductor materials
    Patent number: 4386020
    Abstract: The present invention provides a process for the production of solid ion ductor materials (electrolytes) based on lithium or sodium compounds which stand in thermodynamic equilibrium with their alkali metal and have a high decomposition voltage, wherein two or more binary lithium or sodium compounds with an anion which is formed from one or more elements of the group consisting of nitrogen, phosphorus, arsenic, oxygen, sulphur, selenium, tellurium, hydrogen, fluorine, chlorine, bromine and iodine and which stand in thermodynamic equilibrium with their alkali metal are reacted together in such amounts and for such a period of time that a radiographically phase-pure product is formed.The present invention also provides ion conductor materials based on lithium or sodium compounds, which have the general formula:A.sub.3u+2v+w X.sub.u Y.sub.v Z.sub.

  • Method of measuring activities by means of solid ion conductors
    Patent number: 4352068
    Abstract: A method for measuring the activity of a component of a sample medium using a solid ion conductor having N components wherein N is less than or equal to 3 and having one component which corresponds to the component to be measured is disclosed. The process is carried out by first equilibrating the solid ion conductor with the medium and then with the N-2 adjacent phases of the phase system of the N components of the solid ion conductor. Finally, it is equilibrated with a reference electrode and the voltage between the reference electrode and the medium is measured.
