Abstract
Abstract An electrical element which comprises at least one circuit component consisting of a solid ionic conductor, and wherein the electron flow through the ionic conductor is supressed without substantially hindering the ion flow therethrough, by at least one pn junction formed across the direction of ion flow. The pn junction is formed by at least one of p-conductive and n-conductive zones in or adjoining the ionic conductor and which is capable of being reversed-biased relative to the electron flow. The p-conductive and n-conductive zones comprise a material conductive of the same ions as the ionic conductor.

Claim 2
Dependent Claim
102 words
An electrical component having a circuit comprising between at least two points thereof, a solid ionic conductor so that the current between the two points is substantially an ionic current and means for suppressing the electron flow through the ionic conductor without substantially hindering the ion flow therethrough including at least one pn junction formed across the direction of ion flow in or adjoining the ionic conductor and which is capable of being reversed biased relative to the electron flow and wherein the p-conductive and n-conductive zones of the p-n junction comprise material conductive of the same ions as the ionic conductor.
Claim 3
Dependent Claim
42 words
