Definitions
- the invention relates to a method of manufacturing at least a portion of an electrolytic cell.
- the invention also relates to a part of an electrolytic cell manufactured from such a method.
- the invention also relates to an electrolyzer stack comprising such an electrolytic cell.
- electrolyzer stack usually consists of a block of electrolytic cells, which are stacked in series from an electrical point of view and in parallel from a fluidic point of view, and of sealing joints.
- Each electrolytic cell aims to promote the electrolysis of an electrolytic solution (alkaline water, pure water, unpurified water, salt, aqueous chloride solution, aqueous bromide solution, aqueous hydrochloric acid solution, etc.).
- an electrolytic solution alkaline water, pure water, unpurified water, salt, aqueous chloride solution, aqueous bromide solution, aqueous hydrochloric acid solution, etc.
- an electrolyzer cell for example, the functionality of an electrolyzer cell is to promote the reaction of production of dihydrogen (H2) and dioxygen (O2) gas resulting from the dissociation of water after injecting a direct electric current into an alkaline solution, usually potassium hydroxide (KOH) or sodium hydroxide (NaOH).
- H2 dihydrogen
- O2 dioxygen
- KOH potassium hydroxide
- NaOH sodium hydroxide
- Each electrolytic cell considered as a part mainly metallic and conductive (but some parts of which may be non-metallic), is generally composed of two bipolar plates, framing two intercalators (better known under the English term of "flow field material"), themselves framing two electrodes generally in the form of plates or grids or metallic fabrics.
- said electrodes are generally made of nickel.
- the two electrodes (a cathode and an anode) are separated by a membrane (also called a diaphragm or porous separator in the case of the alkaline electrolyzer cell), which ensures electrical insulation between the two electrodes, the separation of gases as well as ionic conduction within the electrolytic cell.
- the interlayer has two functionalities: i) to provide a low resistivity metallic path between each bipolar plate and the associated electrode and ii) to allow proper circulation of the electrolytic solution for cooling of the electrolyzer stack and transport of the generated gases.
- bipolar plate comes from the fact that since the electrolytic cells are all attached to each other, a bipolar plate N will have a potential: higher compared to the bipolar plate N+l downstream, so that the bipolar plate N will play the role of anode within an electrolytic cell defined by the bipolar plates N and N+l; lower compared to the bipolar plate Nl upstream, so that the bipolar plate N will play the role of cathode within an electrolytic cell defined by the bipolar plates Nl and N.
- the distribution plates which allow the power supply and electrical distribution of the electrolytic cells
- the bottom plates allowing the delimiting of all the electrolytic cells and ensuring the clamping of said electrolytic cells between them and their sealing.
- the electrolyser stack ends with two bottom plates located just before the first electrolytic cell and just after the last stacked electrolytic cell, in other words one bottom plate is located upstream of the block of electrolytic cells and the other bottom plate is placed downstream of the latter in order to physically delimit the two ends of said block of electrolytic cells.
- One aim of the invention is to propose a solution making it easier to manufacture an electrolyzer cell.
- the plate thus manufactured comprises a layer playing both the role of an interlayer of the prior art (by the mesh) and the role of an electrode of the prior art (by the at least one free end of the mesh). Consequently, the manufacture, and in particular the assembly, of an electrolyser cell comprising such a plate is greatly facilitated.
- the bipolar plate is also manufactured by additive method.
- the bipolar layer and/or plate is printed in a nickel-based material.
- the layer is a first layer, the method comprising the step of printing on a second face of the bipolar plate by additive manufacturing at least one second layer, a first face of which is integral with the second face of the bipolar plate and the second face of which forms at least one free end, the second layer being formed of a mesh drawing a honeycomb structure.
- the first layer is the same shape as the second layer.
- the second layer is in the same material as the first layer.
- the two layers are printed at the same time.
- the bipolar plate is a first bipolar plate, the method comprising the step of printing on a first face of a second bipolar plate by additive manufacturing at least one layer, a first face of which is integral with the first face of the bipolar plate and of which the second face forms at least one free end, the layer being formed of a mesh forming an alveolar structure.
- the two bipolar plates are joined together while being separated by a membrane, so that the second faces of the layers of the two bipolar plates are both facing the membrane.
- the invention also relates to a part of an electrolytic cell manufactured by a method as mentioned above.
- the invention also relates to an electrolyzer stack comprising a portion of cells as mentioned above.
- Figure 1 is a diagram illustrating different steps of manufacturing a part of an electrolytic cell according to a particular implementation of the invention
- Figure 2 schematically represents a portion of an electrolyzer stack integrating the cell part whose manufacture was illustrated in Figure 1,
- Figure 3 schematically represents a variant of the electrolyzer cell portion illustrated in Figure 2.
- a bipolar plate 1 is chosen.
- the bipolar plate 1 is for example a bipolar plate already manufactured by manufacturing methods of the prior art and for example a bipolar plate manufactured by the present applicant.
- the bipolar plate 1 is made of a material capable of withstanding the corrosive environment prevailing inside the electrolytic cell.
- the bipolar plate 1 is for example nickel-based and is for example made of nickel or nickel-plated carbon steel.
- the bipolar plate 1 is further shaped so as to have a first main face 2a and a second main face 2b.
- a first layer 3 is printed on the first main face 2a, by additive manufacturing, having a first face 4a (i.e. the first layer printed on the first main face 2a) and a second face 4b (i.e. the last printed layer of the first layer 3).
- the first layer 3 is preferably of a single material.
- the first layer 3 is made of the same material as that of the bipolar plate 1.
- the first layer 3 is nickel-based and is, for example, made of nickel or nickel-plated carbon steel.
- the first layer 3 is formed of a mesh drawing an alveolar structure.
- the first layer 3 draws at least a plurality of loops.
- the lowest point of the loop is the only point of the loop in contact with the first main face 2a.
- first layer 3 is thus integral with the first main face 2a.
- the contact between the first face 4a and the first main face 2a is not a plane/plane contact over the entire surface of the first main face 2a. It is noted that due to the alveolar structure of the first layer 3, the contact between the first face 4a and the first main face 2a is also not a plurality of linear contacts. In reality, the contact between the first face 4a and the first main face 2a is formed by a plurality of point contacts between the first layer 3 and the first main face 2a. In reality, the contact between the first face 4a and the first main face 2a is formed only by a plurality of point contacts between the first layer 3 and the first main face 2a. There is thus neither surface contact nor linear contact between the first layer 3 and the first main face 2a.
- the first layer 3 thus has two functions: providing a low resistivity metallic path between the bipolar plate 1 and its second face 4b, allowing appropriate circulation of the electrolytic solution for cooling the electrolyzer stack and transporting the gases generated.
- the second face 4b of the first layer 3 forms at least one free end. It is noted that due to the alveolar structure of the first layer 3, there is in reality a plurality free ends of the first layer 3.
- a second layer 5 having a first face 6a (i.e. the first layer printed on the second main face 2b) and a second face 6b (i.e. the last printed layer of the second layer 5) is also printed on the second main face 2b by additive manufacturing.
- This third step 103 can be carried out simultaneously with the second step 102 or successively with the second step 102.
- the second layer 5 is preferably made of a single material.
- the second layer 5 is formed from the same material as the first layer 3 or from a different material.
- the second layer 5 is made of the same material as that of the bipolar plate 1.
- the second layer 5 is nickel-based and is, for example, made of nickel or nickel-plated carbon steel.
- the second layer 5 is formed of a mesh drawing an alveolar structure.
- the second layer 5 draws at least a plurality of loops.
- the lowest point of the loop is the only point of the loop in contact with the second main face 2b.
- the second layer 5 is thus integral with the second main face 2b.
- the contact between the first face 6a and the second main face 2b is not a plane/plane contact over the entire surface of the second main face 2b. It is noted that due to the alveolar structure of the second layer 5, the contact between the first face 6a and the second main face 2b is also not a plurality of linear contacts. In reality, the contact between the first face 6a and the second main face 2b is formed by a plurality of point contacts between the second layer 5 and the second main face 2b. In reality, the contact between the first face 6a and the second main face 2b is formed only by a plurality of point contacts between the second layer 5 and the second main face 2b. There is thus neither surface contact nor linear contact between the second layer 5 and the second main face 2b.
- the second layer 5 thus has two functions: providing a low resistivity metallic path between the bipolar plate 1 and its second face 6b, allowing appropriate circulation of the electrolytic solution for cooling the electrolyzer stack and transporting the gases generated.
- the second face 6b of the second layer 5 forms at least one free end. It is noted that due to the alveolar structure of the second layer 5, there is in reality a plurality of free ends of the second layer 5.
- the second layer 5 is identical to the first layer 3 in shape and/or material.
- This assembly 7 can play both the role of a bipolar plate but also of an interlayer and an electrode for a first electrolytic cell 9 (via the first layer 3) as well as the role of a bipolar plate but also of an interlayer and an electrode for a second electrolytic cell 10 (via its second layer 5), second electrolytic cell 10 directly adjacent to the first electrolytic cell 9.
- the assembly 7 therefore makes it possible to play the role of an anode or a cathode for the first electrolytic cell 9 and the role of a cathode (respectively anode) for the second electrolytic cell 10.
- Such an assembly 7 also makes it possible to optimize the electrolysis inside the first electrolytic cell 9 and the second electrolytic cell 10 in particular due to the homogeneity of the structure of said assembly 7.
- the assembly 7 proves in particular to be homogeneous between the interior of each layer 3, 5 (playing the role of the interlayer) and the corresponding second face 4b, 6b (playing the role of the electrode): there is in fact no junction between these two sub-layers since everything is printed at the same time.
- an electrolyzer stack comprising such an assembly 7 is simplified, particularly in terms of assembly.
- the contact between the membrane 8 and each of the second faces 4b, 6b of the layers 3, 5 in contact with it is not a plane/plane contact over the entire surface of the membrane 8. It is noted that, due to the alveolar structure of the second layer 5 and the first layer 3, the contacts between the membrane 8 and each of the second faces 4b, 6b of the layers 3, 5 are also not a plurality of linear contacts. In reality, the contact between the membrane 8 and each of the second faces 4b, 6b of said layers is formed by a plurality of point contacts (the free ends of the layers 3, 5) between the layer considered 3, 5 and the membrane 8.
- the second layer 5 draws at least a plurality of loops, for at least one loop, the highest point of the loop is the only point of the loop in contact with the membrane 8.
- the highest point of the loop is the only point of the loop in contact with the membrane 8.
- first assembly 7, a first membrane 8, a second assembly 7, a second membrane 8,... it is possible to create a block of electrolytic cells 11 extending longitudinally in a general direction A.
- Said block of electrolytic cells 11 can then be used in a standard electrolyser stack (as a replacement of part or all of the electrolytic cell block of the prior art).
- the block of electrolytic cells 11 thus defined extends longitudinally in the general direction A (the main faces of at least one of the bipolar plates 1 extending in planes normal to the general direction A).
- Figure 2 shows a possible mode of application of this block of electrolytic cells 11 in which the general direction A extends vertically.
- the first layer 3 and/or the second layer 5 is shaped so that its mesh is similar or identical to that of an interlayer of the prior art and/or so that the free ends of the mesh are similar or identical to the contact zones of an electrode of the prior art with the membrane 8.
- the mesh of the first layer 3 and/or of the second layer 5 can thus be regular (as is the case for the interlayers of the prior art).
- the first layer 3 and/or the second layer 5 is shaped differently than a mesh of an interlayer of the prior art and/or the free ends of the mesh are shaped differently than the contact zones of an electrode of the prior art with the membrane 8.
- the first layer 3 and/or the second layer 5 can thus be formed from a mesh with less regular meshes than the existing and/or non-regular meshes.
- the first layer 3 and/or the second layer 5 can thus be formed of a mesh composed on at least one zone (and optionally on the entire first layer 3 and/or the second layer 5) of at least one pattern repeating in at least one direction of space and preferably at least two directions of space orthogonal to each other and optionally in three directions of space orthogonal to each other.
- the pattern may be a geometric pattern and for example a polygonal pattern (square, hexagon, etc.) or circular.
- the aforementioned pattern(s) is/are repeated at least in one plane of the layer considered, a plane which is orthogonal to the thickness of said layer (the thickness of the layer being its smallest dimension).
- the bipolar plate 1 may also be manufactured by additive manufacturing.
- the bipolar plate 1 may be entirely manufactured during a first step by additive manufacturing (the layers then being printed on its faces) or may be manufactured partially on one side only so as to first finish printing the first layer 3 before continuing to print the bipolar plate 1 then the second layer 5.
- one of the layers 3, 5 may be the first 3 printed then the bipolar plate 1 then the second 5 of the two layers 3, 5.
- Other printing orders are of course possible.
- the bipolar plate 1 may then optionally be printed in the same material as that of at least one layers 3, 5 or in another material.
- At least the first layer 3 or the second layer 5 may be printed from at least two different materials. Only one layer 3 or 5 may be printed on the bipolar plate 1.
- One or more joints may also be arranged between two aforementioned assemblies 7.
- the aforementioned assemblies 7 may be fixed in pairs or be fixed by means of tie rods passing through the entire block of electrolytic cells 11.
- the bipolar plates 1 and/or the layers 3, 5 will for example be shaped to include one or more orifices ensuring their fixings within the electrolyser stack.
- the second layer 5 may not be identical to the first layer 3 in terms of materials and/or shape.
- the bipolar plate 1 as well as its two layers 3, 5 are based on nickel
- at least one area of the bipolar plate 1 and/or of at least one of the layers 3 or 5 may be in another material.
- at least one of the layers may be printed in a material based on a material other than nickel and for example be printed in a material based on chromium, iron, ...
- the honeycomb structure may have a shape other than that indicated.
- the structure may include at least one area without a repeating pattern and/or may have at least one non-homogeneous area. If a pattern is present, it may be non-geometric and/or non-polygonal.
