Definitions

  • the present invention relates to a fluid distributing device according to the preamble of Claim 1.
  • a fluid distributing device of this kind is disclosed by the 'Abstract' of Japanese Patent Application 58-155666.
  • this device two grids provided with diamond-shaped meshes are placed on top of one another.
  • the mesh width of the various grids differs, so that the reactant (gas) can spread across the electrode in all directions.
  • the reactant gas
  • the electrodes For fuel cells, consisting at least of an anode, cathode, electrolyte and separator plate, it is important to provide the electrodes with gas which takes part in the reaction leading to the generation of electricity, and to discharge gas which is formed during the reaction. To this end, the gas should be spread over the active surface of the anode or cathode in a manner which is as evenly distributed as possible.
  • a pressure drop of this kind can be realized, in particular, by means of long channels.
  • the channels are produced by milling channels from a solid block of graphite, which is particularly complicated and time-consuming.
  • the boundaries of the channels are required to be electrically conductive, because the current generated in the electrodes has to be conducted to the separator plate. Moreover, the boundary of the channels has to be resistant to the fluid used, which can be aggressive under certain circumstances.
  • SPFC cells Solid Polymer Fuel Cell
  • the channel can be led across the electrode surface in any chosen manner, starting at the inlet opening and ending at the outlet.
  • connections between channels are possible at any desired location, as well as at the inlet and outlet openings.
  • two adjacent channels are connected to one another at the point which is situated furthest from the inlet opening, so that a serpentine-like channel is formed.
  • plates of this kind from which a channel is constructed, are particularly easy to manufacture. If the plates comprise, for example, metal plates, the openings can be produced in a particularly simple manner by punching or (electrochemical) etching.
  • a serpentine-like channel By using two metal plates provided with a series of openings, a serpentine-like channel can be formed.
  • the fluid distributing device according to the invention can be used in all exchanging surfaces. This means heat exchangers and electrochemical cells in general.
  • the above-described plates which form the channels can be produced from any material known from the prior art, such as graphite. Preferably, however, stainless steel is used. This is a comparatively inexpensive material which can be readily provided with openings by punching.
  • One of the plates can comprise the backing of the electrode. By making openings therein, a continuous channel can be obtained.
  • a backing of this kind generally has a thickness of a few tenths of a millimetre.
  • the openings which are to be made can have any form known from the prior art, but are preferably of essentially rectangular design, the longest side of the rectangle extending in the direction of flow of the fluid in question.
  • a sealing ring can be arranged around the plates which form the channels.
  • the plates may optionally be firmly connected to one another.
  • Fig. 1 shows, in perspective view, a cut-away part of a fuel cell
  • Fig. 2 shows a top view of the structure according to Fig. 1;
  • Fig. 3 shows the bottom plate of the structure according to Figs. 1 and 2;
  • Fig. 4 shows the top plate of the structure according to Figs. 1 and 2.
  • Fig. 1 shows part of a fuel cell, specifically the part which adjoins an electrode, for example the anode 2.
  • the electrolyte, cathode and the current collector which adjoins the cathode are not shown.
  • the part which is connected to the cathode can, in principle, be designed in the same way as the part which is arranged on the anode, which will be explained in more detail below.
  • a ring 1 is placed on the anode 2.
  • Plate 3 is arranged inside the ring, followed by plate 4. Details of plate 3 emerge from Fig. 3, while details of plate 4 emerge from Fig. 4.

  • the plate itself preferably consists of a stainless steel material, ⁇ a indicates perforations which ensure the transportation of the fluid in the longitudinal direction, in a manner which will be described in more detail hereinbelow.
  • 8b indicates punched-out pieces, which provide the connection between the channels which have been formed.
  • Fig. 4 shows the second, or top, plate 4. It will be seen that a pattern of perforations is likewise present. This pattern differs from the pattern shown in Fig. 3.
  • a zigzag-like channel is formed. This must be differentiated from the meander or serpentine curve which is shown by arrow 14.
  • a number of parallel channels are formed, indicated by 9-12. These are connected, on the one hand, to an opening 6 in ring 1 as inlet, and, on the other hand, to opening 7 of the same ring as outlet. These openings form part of gas-lead-through channels.
  • the length of the openings mention may be made of a range between 1 and 200 mm, more particularly between 2 and 100 mm, and preferably between 2 and 50 mm.
  • the width of the openings is preferably between 0.5 and 10 mm, in particular between 1 and 5 mm, and more particularly between 2 and 4 mm.
  • the width of the areas between the perforations is likewise important, in order to provide the contact surface between electrode and separator plate 5 in electrochemical cells. Preference is given to a width lying between 0.2 and 10 mm, in particular between 0.5 and 5 mm, and more particularly between 0.5 and 2 mm.
  • the thickness of the plates can vary within a range of values, and is, inter alia, dependent on the material used and the fluid which flows through them. This thickness can lie between, for example, 0.05 and 5 mm, in particular between 0.1 and 2 mm, and more particularly between 0.2 and 1 mm.
  • the channels interact on one side with the anode 2 and are enclosed on the other side by partition or separator plate 5. It will be understood that this plate 5 can be replaced by another electrode or an actively exchanging part.

Abstract

Dispositif de distribution de fluide, dans lequel un fluide vient en contact d'échange avec une surface. Ce fluide peut être, par exemple, un gaz dans une pile électrochimique, telle qu'une pile à combustible. Afin de créer des canaux compliqués de façon particulièrement simple et économique, de manière à distribuer un fluide de ce type aussi uniformément que possible au-dessus de la surface d'échange, l'invention propose de construire ces canaux à partir de plusieurs plaques perforées (3, 4). Les ouvertures (8) sont disposées de manière à se recouvrir partiellement, quand les plaques sont placées exactement les unes au-dessus des autres. Ces canaux sont scellés latéralement, ce qui permet d'effectuer une mesure exacte des gaz à travers les différents canaux, ainsi que d'assurer une chute de pression suffisante pour évacuer toute humidité susceptible de se former.
