An orthographic projection of the pressure relief structure (24) toward the first sidewall (14) at least partially falls within the recessed structure (141). A part of the first sidewall (14) is recessed outward to form the recessed structure (141), and the orthographic projection of the pressure relief structure (24) toward the first sidewall (14) at least partially falls within the recessed structure (141), and therefore, a distance between the pressure relief structure (24) and the first sidewall (14) can be increased, and a cushion space (1411) between the pressure relief structure and the first sidewall (14) can be enlarged.

Resumen de: EP4597010A1
The present application provides a cathode for an oxygen processing device, and an oxygen processing device and refrigerator, wherein the cathode comprises: a mesh conductive film comprising at least one movable intersection point configured to absorb stress through movement. When the cathode is subjected to stress, since the movable intersection point on the mesh conductive film can absorb stress through movement, the stress can be transferred to and "concentrated" at the movable intersection point. The movement of the movable intersection point will not cause significant changes in a shape of the mesh conductive film. Therefore, the mesh conductive film as a whole will hardly undergo significant deformation due to stress, which is beneficial for improving the structural stability of the cathode.
