Abstract

A cassette (1) for an electrolyzer is disclosed. The cassette (1) comprises 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).
