Abstract
The present disclosure relates to an electrode of an electrochemical measuring system and includes a housing having a chamber in which an electrolyte is arranged, and a potential-forming element which is at least partially arranged in the chamber such that the electrolyte at least partially wets the potential-forming element. A discharge line is made of coinage metal or of an alloy comprising a coinage metal and contacts the potential-forming element. A closure element closes the housing and guides discharge line therethrough. An adhesion promoter which comprises a glass and/or a glass-ceramic material and is arranged between the closure element and the discharge line.
Claims13
An electrode of an electrochemical measuring system, comprising:
- a housing having a chamber in which an electrolyte is arranged;
- a potential-forming element which is at least partially arranged in the chamber such that the electrolyte at least partially wets the potential-forming element;
- a discharge line which is made of coinage metal or of an alloy comprising a coinage metal and which contacts the potential-forming element;
- a closure element which closes the housing and through which the discharge line is guided;
- and
- an adhesion promoter which comprises a glass and/or a glass-ceramic material and is arranged between the closure element and the discharge line,
- wherein the adhesion promoter has a working range below 700° C., in which the dynamic viscosity of the adhesion promoter has a value between 103 dPas to 108 dPas.
A method for producing an electrode of an electrochemical measuring system, comprising the steps of:
- applying an adhesion promoter to a discharge line which is made of coinage metal or of an alloy comprising a coinage metal and which contacts a potential-forming element, wherein the application takes place at a temperature which is selected to be lower than the melting temperature of the discharge line and wherein the temperature for applying the adhesion promoter is less than 700° C.;
- and
- inserting at least a section of the discharge line provided with the adhesion promoter into a closure element, which closes a housing containing an electrolyte such that the potential-forming element contacts the electrolyte.
