Abstract

An electrolyte plate (3a, 3c) for an electrolyzer cassette (1), the electrolyzer cassette (1) further comprising at least one cooling plate (2), is disclosed. 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).
