Abstract: Disclosed herein are embodiments of a cable assembly including an optical fiber cable connectorized at one or both ends. The optical fiber cable of the cable assembly includes a cable jacket having an inner surface and an outer surface. The inner surface defines a central bore extending along a longitudinal axis of the optical fiber cable, and the outer surface defines an outermost surface of the optical fiber cable. At least one tensile strand is disposed between the inner surface and the outer surface of the cable jacket, and at least one optical element is disposed within the central bore of the cable jacket. Also disclosed herein are a method of preparing a cable assembly by attaching a connector to the optical fiber cable as and a method of preparing the optical fiber cable.

Abstract: A spacer for an electrolyzer cell of substantially annular shape comprises: a peripheral part having two parallel principal faces opposite each other, the distance separating the two principal faces defining a thickness of the spacer, and an internal part having a thickness strictly less than the thickness of the spacer, the peripheral part and the internal part being in one piece and connected to each other forming an internal annular shoulder so that the internal part has a substantially annular intermediate face extending in a plane parallel to the two principal faces of the peripheral part and situated between the two principal faces.

Abstract: A seal for an electrolyser cell and an electrolyser cell provided with such a seal. A seal (100) for an electrolyser cell comprising a core (101) and a shell (201). The core (101) is generally annular and has two faces mutually opposite each other in a thickness direction and at least two openings (111, 113). The two openings (111, 113) are through-openings in the thickness direction and are substantially diametrically opposed to each other. The shell (201) at least partially covers the two faces, leaving the two openings (111, 113) at least partially flee. The shell (201) has at least one first rib (203) extending over a first (103) of the two faces according to a contour enclosing an inner edge (107) of the core (201) and the two openings (111, 113) in such a way as to allow a fluid to circulate between the two faces in the thickness direction.

Abstract: The inventive stage system for producing hydrogen consists of at least two upstream/downstream stages, respectively, each of which comprises, optionally, a catalytic reactor (C1 to C5) followed by a separator comprising a space (E1 to E4) for circulation of a gaseous mixture contacting at least one oxygen extracting membrane and a hydrogen collecting space, wherein the reactor (C1) of the upstream stage is connected to a reaction gaseous mixture source, the circulation stage (E1) of the upstream stage separator is connected to the reactor (C2) of the downstream stage and the spaces for extracting/collecting oxygen from two separators are connected to a hydrogen collecting circuit (TC, 8) which is common for two stages.
