Abstract
Embodiment having a channel for transporting a fluid A backflow limiting structure (2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h, 2i) which allows a flow of fluid in one direction (30). The backflow limiting structure (2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h, 2i) can be arranged in a channel (1a, 1b). The channel (1a, 1b) can be part of an electrolyzer (24), fuel cell and / or storage cell. A resistance barrier (5a, 5b, 5c, 5d, 5e, 5f) of a backflow limiting structure (2a, 2b, 2c, 2d) provides an auxiliary section (10a, 10b, 10c, 10d) and a main section (9a, 9b, 9c, 9d). The backflow limiting structure (2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h, 2i) interacts with a fluid, creating a different resistance depending on the direction of flow in the resistance barrier (5a, 5b, 5c, 5d, 5e, 5f).
