Definitions

  • the opposite surface of the electrolyte plate to the one in the bending direction of the flanges may be essentially flat. Similarly to the embodiments described above, this ensures a good and firm contact between the electrolyte plate and the membrane.
  • the openings formed in the porous area may be formed with a larger length than width. According to this embodiment, the openings have an elongate shape. The shape and size of the openings influences the flow of gasses (hydrogen or oxygen).
  • the openings formed in the porous area may be symmetric with two halves mirroring each other.
  • the symmetric feature of the openings evens out the deep drawn stresses induced with pressing forces and reduces or even prevent the occurrence of deformations.
  • the openings formed in the porous area may have a width at a centre portion, which is smaller than an upper width or diameter of a contact column formed in a neighbouring cooling plate when the electrolyte plate and the cooling plate are connected to each other in an electrolyzer cassette.
  • the contact column ensures appropriate spacing between the electrolyte plate and the neighbouring cooling plate, and may further ensure electrical contact between the plates. However, this is obtained with minimum obstruction of flow through the openings formed in the porous area due to the contact column.
  • Fig. 3B is an illustration of openings in an electrolyte plate formed by a recessed section
  • Fig. 1 illustrates a basic setup of a cassette 1 for an electrolyzer according to the present invention.
  • the cassette 1 is formed of two cooling plates 2 and two electrolyte plates 3a, 3c, respectively an anodic plate 3a, and a cathodic plate 3c.
  • the flanges 11c will then reach towards the respective cooling plate 2, preferably without contacting it, and thus into the respective electrolyte path 6a, 6c.
  • Figs. 5A-5D illustrate the two cooling plates 2 positioned between an anodic electrolyte plate 3a and a cathodic electrolyte plate 3c.
  • Outer gaskets 31 may be positioned at the outer circumference of the respective openings 7in, 7out, 8in, 8out, 9in, 9out to seal towards the externals when connected to another cassette 1.
  • the openings combine into opening volumes that reach through all four plates 3a, 3c, 2 of all cassettes 1.
  • a lower inner gas barrier 26a may be positioned at the gas barrier drain 27, immediately at the side facing the active area below the inner gas barrier drain 27.
  • fixations 4a, 13a', 13', 14', 15, 16 could be positioned at regular intervals at the circumference of the membrane 4.
  • the contact columns 19 may be fixedly attached to the respective electrolyte plates 3a, 3c, e.g. by welding or soldering. Alternatively, the contact columns 19 may simply be pushed into contact with the respective electrolyte plates 3a, 3c by pressing the plates 2, 3a, 3c together.
  • the area of the cooling plates 2 formed with cooling cells 17 may be adapted to be aligned with the active area of the electrolyte plates 3a, 3c, enabling a control of the temperature in the gas generating processes occurring in the electrolytic fluids in the electrolyte flow paths 6a, 6c.

Abstract

Une plaque d'électrolyte (3a, 3c) pour une cassette d'électrolyseur (1) est divulguée, la cassette d'électrolyseur (1) comprenant en outre au moins une plaque de refroidissement (2). La plaque d'électrolyte (3a, 3c) est formée avec au moins une ouverture (7in, 7out) pour qu'un fluide de refroidissement passe la plaque d'électrolyte (3a, 3c), au moins une entrée de fluide d'électrolyte (8in, 9in) pour qu'un fluide électrolytique passe la plaque d'électrolyte (3a, 3c) et au moins une sortie de gaz (8out, 9out) pour qu'un gaz passe la plaque d'électrolyte (3a, 3c). Une zone poreuse est formée entre la ou les entrées de fluide d'électrolyte (8in, 9in) et la ou les sorties de gaz (8out, 9out), la zone poreuse étant formée avec des ouvertures (11) conçues pour faire passer un gaz à travers la plaque d'électrolyte (3a, 3c) entre une membrane (4) à positionner sur un côté de la plaque d'électrolyte (3a, 3c) et un trajet de fluide d'électrolyte (6a, 6c) positionné de l'autre côté de la plaque d'électrolyte (3a, 3c).
