Abstract: A gas diffusion layer having a layer (2) comprising fibers (1), whereby the fibers (1) are partially provided with a coating material (3), whereby the fibers (1) lie against each other at contact sites (4) and whereby the layer (2) has boundary surfaces (5) facing the surroundings—in terms of achieving the envisaged objective of ensuring an optimal electric conductivity—is characterized in that the fibers are freed of coating material (3) at the contact sites and/or at the boundary surfaces. Furthermore, a method is proposed for the production of a gas diffusion layer, said method comprising the step that the coating material (3) is selectively removed from the fibers (1) in certain areas.

Abstract: A pressure switch is described with a pressure connection (11), with an electrical pressure sensor (19) to generate a pressure-dependent electrical signal, with an operator-device and/or an adjusting device (16-18) to input at least one pressure switch threshold and with at least one electrical switch output (16-18) [sic; 13,14]. The pressure switch can be adjusted by operation of the operator device (16-18) in such a manner that the electrical signal corresponding to the instantaneously applied pressure (p) is saved as the first saved pressure value (S1) and the electrical signal corresponding to a pressure (p) applied temporally thereafter, is saved as a second saved pressure value (S2), where these two saved pressure values (S1, S2) define the pressure switching threshold(s) in the operating mode. Thus, the saved pressure values can be specified very easily and in a variable manner and saved, and a great variability of operating modes is possible.
