Abstract
An electrolyte conductor (1) has a nonwoven fabric (2), onto which a plastic film (3) is laminated. A process is provided for the manufacture of the electrolyte conductor (1). An electrochemical gas sensor (10) is provided with such an electrolyte conductor (1). A gas-measuring device is provided with such a gas sensor (10).
Claims20
A process for manufacturing an electrolyte conductor comprising a nonwoven fabric;
- and a plastic film laminated onto the nonwoven fabric, the process comprising the steps of:
- providing a first web of nonwoven fabric;
- providing a second web of plastic film;
- laying the first web of nonwoven fabric and the second web of plastic film on top of one another;
- bonding the first web and the second web together to form a composite web by laminating, wherein the second web of plastic film is laminated partially onto only one side of the first web of nonwoven fabric in a pattern, the first web of nonwoven fabric comprising another side located opposite the one side, wherein the another side is free of lamination;
- and
- punching or cutting a two-dimensional shape out of the composite web or winding up the composite web to form a roll.

A process for manufacturing an electrolyte conductor, the process comprising the steps of:
- providing a first web, the first web comprising a nonwoven fabric;
- providing a second web, the second web comprising a plastic film;
- laying the first web and the second web on top of one another;
- partially laminating the second web onto only a single side of the first web in a pattern to form a composite web after laying the first web and the second web on top of one another, the first web comprising a second side opposite the single side, wherein the second side is not laminated;
- and
- punching or cutting a two-dimensional shape out of the composite web or winding up the composite web to form a roll.
