Abstract: A cassette (1) for an electrolyzer includes two cooling plates (2) contacting each other and forming a cooling flow path (5) between them, and two electrolyte plates (3a, 3c), each electrolyte plate (3a, 3c) contacting one of the cooling plates (2). At least a section of the cooling flow path (5) is split into cooling cells (17) each connecting to a cooling cell supply channel (20) via a cooling cell inlet (21) and to a cooling cell return channel (22) via a cooling cell outlet (23), forming a cooling flow path through each cooling cell (17) from the cooling cell inlet (21) to the cooling cell outlet (23). The cooling cells (17) are distributed across the cooling plates (2) along two directions.

Abstract: A cassette (1) for an electrolyzer includes a cooling plate (2) and an electrolyte plate (3a, 3c) defining an electrolyte flow path (6a, 6c) between them. The electrolyte plate (3a, 3c) is formed with at least one electrolyte fluid inlet (8in, 9in) at a first end section and at least one gas outlet (8out, 9out) at a second, opposite end section and defines an active area between the first end section and the second end section. At least one of the at least one gas outlet (8out, 9out) is partly surrounded by an outlet blockade (28) with an opening (29) formed therein, allowing gas only to leave the second end section towards the at least one gas outlet (8out, 9out) via the opening (29) in the outlet blockade (28).

Abstract: A cassette (1) for an electrolyzer includes two cooling plates (2) and two electrolyte plates (3a, 3c), in the form of an anodic electrolyte plate (3a) and a cathodic electrolyte plate (3c). The two cooling plates (2) contact each other at one surface forming a cooling flow path (5) between them. Each of the cooling plates (2) contacts an electrolyte plate (3a, 3c) at the other, opposite surface and forming an anodic electrolyte flow path (6a) between one of the cooling plates (2) and the anodic electrolyte plate (3a) and a cathodic electrolyte flow path (6c) between the other cooling plate (2) and the cathodic electrolyte plate (3c). The electrolyte plates (3a, 3c) and cooling plates (2) are each formed with cooling openings (7 in, 7out) for a cooling fluid to pass the plate (2, 3a, 3c), at least one anodic electrolyte fluid inlet (8 in) for an anodic electrolytic fluid to pass the plate (2, 3a, 3c), at least one cathodic electrolyte fluid inlet (9 in) for a cathodic electrolyte fluid to pass the plate (2, 3a, 3c), at least one anodic gas outlet (8out) for an anodic gas to pass the plate (2, 3a, 3c), and at least one cathodic gas outlet (9out) for a cathodic gas to pass the plate (2, 3a, 3c).

Abstract: A cassette (1) for an electrolyzer includes a cooling plate (2) and an electrolyte plate (3a, 3c) defining an electrolyte flow path (6a, 6c) between them. The electrolyte plate (3a, 3c) is formed with at least one electrolyte fluid inlet (8in, 9in) at a first end section and at least one gas outlet (8out, 9out) at a second, opposite end section and defines an active area between the first end section and the second end section. An inner gas barrier (26) is formed between the second end section with the at least one gas outlet (8out, 9out) and the active area, and the inner gas barrier (26) is formed with a drain (27).

Abstract: An electrolyte plate (3a, 3c) for an electrolyzer cassette (1), the electrolyzer cassette (1) includes at least one cooling plate (2). The electrolyte plate (3a, 3c) is formed with at least one opening (7in, 7out) for a cooling fluid to pass the electrolyte plate (3a, 3c), at least one electrolyte fluid inlet (8in, 9in) for an electrolytic fluid to pass the electrolyte plate (3a, 3c), and at least one gas outlet (8out, 9out) for a gas to pass the electrolyte plate (3a, 3c). A porous area is formed between the at least one electrolyte fluid inlet (8in, 9in) and the at least one gas outlet (8out, 9out), the porous area being formed with openings (11) adapted to pass gas across the electrolyte plate (3a, 3c) between a membrane (4) to be positioned at the one side of the electrolyte plate (3a, 3c), and an electrolyte fluid path (6a, 6c) positioned at the other side of the electrolyte plate (3a, 3c).
