Abstract

A cassette (1) for an electrolyzer is disclosed. The cassette (1) comprises 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 (7in, 7out) for a cooling fluid to pass the plate (2, 3a, 3c), at least one anodic electrolyte fluid inlet (8in) for an anodic electrolytic fluid to pass the plate (2, 3a, 3c), at least one cathodic electrolyte fluid inlet (9in) 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).
