Definitions
- the invention relates to a device for producing or storing electrical energy, allowing activation controlled by the user, as well as its manufacture and use.
- This device can in particular allow the activation and / or control of fuel cells.
- Fuel cells operate by transporting ions, usually protons, between two electrodes.
- a medium placed between the anode and the cathode must be able to conduct the hydroxonium ions (H30 + ), also denoted in a simplified version H + , but not the electrons.
- This electrolyte in fuel cells comprises a proton exchange membrane, such as in Proton Exchange Membrane Fuel Cells or Polymer Electrolyte Membrane Fuel Cells (PEMFC) and an aqueous liquid allowing ionic displacement.
- PEMFC Proton Exchange Membrane Fuel Cells
- Technological advances have made it possible to develop dihydrogen-dioxygen batteries or enzymatic batteries, in particular glucose-dioxygen enzyme batteries, which are environmentally friendly (cf.
- WO2018 / 185417 on behalf of the CNRS.
- Such cells are compact and can work at low temperature (less than 80 ° C.), optionally with a polymer electrolyte (PEMFC) or an aqueous electrolyte (aqueous solutions, biological fluids). They can be used not only in stationary mode but also in portable mode. These batteries may therefore be suitable for generating low currents and for domestic and / or individual uses.
- PEMFC polymer electrolyte
- aqueous electrolyte aqueous solutions, biological fluids.
- These batteries may therefore be suitable for generating low currents and for domestic and / or individual uses.
- the activation and / or control, or even the deactivation, of such devices remain problematic. To date, the control is carried out by interrupting the electrical circuit.
- the contact of the elements of the cell can degrade these elements, in particular when they contain biological materials (vegetable matter, enzymes ).
- the liquid necessary for the operation of the cell is advantageously added to the membrane at the very moment of its first operation. This is generally carried out by an external addition of liquid to the membrane of the device, in particular by pipette, as described in the patent application US2011287328A1 in the name of Sony, or by the use of a bottle as described in the patent application US2010 / 0297477, on behalf of POWER KNOWLEDGE LTD.
- the problems associated with such devices are also numerous: First of all, the user must have access to a source of liquid (aqueous) having sufficient purity and quality for the required use and the correct functioning of the battery. It must also be able to quantify the volume to be added. This requires the provision of a separate measuring device such as a disposable pipette, or pod, which increases the costs and environmental impact of the device. In addition, the device must include a means for introducing the liquid onto the membrane. The fact that the membrane can be accessible from the outside involves in particular additional contamination problems. Finally, batteries of this type are difficult to store because they can be sensitive to the humidity level of their environment.
- An object of the invention is therefore a device for producing and / or storing electrical energy, in particular electrochemical, characterized in that it comprises:
- a separator such as a diffusion layer, allowing the transfer of at least one compound capable of triggering and / or allowing production and / or storage of electrical energy, arranged between the anode and the cathode, and
- the reservoir in English "storage tank", like any reservoir, defines a place distinct from that of the production and / or storage of energy where the contents of the reservoir are used. It can be adjacent, or even overlapping, but does not define a strictly identical place. In other words, the reservoir and the electrochemical cell are distinct and preferably separate elements. This reservoir can advantageously make it possible to separate the contents of the reservoir from the anode and the cathode, in whole or in part.
- the reservoir and its contents therefore participate in the transition from an inactive to active state of the device.
- the deformation of the reservoir and the release of its contents make it possible to create an ability to activate the device.
- the deformation of the reservoir can therefore allow either to directly trigger the production or storage of energy, or to create an intermediate activation state of the device.
- the device can furthermore comprise one or more activation means, the configuration of which is chosen to allow either the activation, or the increase, or the decrease, or the stopping (or the deactivation) of the. energy production and / or storage.
- the device can also comprise a switch which can be advantageously manipulated by the user.
- a switch may for example comprise a circuit breaker such as a removable tab.
- This switch can then be manipulated by the user before or after bringing the compound capable of triggering production or storage of electrical energy and the separator into contact.
- the activation can be direct or be carried out in several stages. Activation can be carried out, for example, firstly by pressing on the reservoir (and possibly the release of fluids within the reservoir) then by removing a circuit breaker tab by the user.
- the activation of the device by the user in particular sequentially in several steps or in just one, is also an object of the invention.
- the anode and / or the cathode comprises an enzyme.
- the reservoir is breakable, pierceable and / or deformable in whole or in part.
- it can comprise a part which can be destroyed under the action of a user it can comprise a container, for example in the form of a shell (advantageously deformable and / or flexible) having an opening and retention means closing off the opening of the hull or the container.
- This shell for example an optionally semi-spherical dome, therefore forms a cavity containing the compound and comprises an opening.
- the retention means is advantageously a layer, or film, of separation closing off the opening of the shell, or of the container, and forming therewith a closed and preferably impermeable receptacle.
- This type of reservoir is also known by its English name of “blister pack”, or “blister”. It can be characterized by the fact that the opening area is proportionately large, for example 25 to 45%, relative to the total area of the tank.
- the retention means make it possible to retain the compound inside the reservoir and in particular to separate them, at least in part from the anode and the cathode.
- the choice of the material (s) used to form the shell and the separation layer depends on several factors. For example, and if it is intended to accommodate a liquid, a semi-liquid, a gel or substances that can migrate, a Laminate material comprising a layer of a resistant material is placed. It is also possible to choose materials which are inert [3] with respect to the material stored in the tank or materials which absorb water vapor, oxygen (or both) to control the atmosphere at hand. inside the tank and thus preserve the product contained (increased stability over time) [4] It is also possible to choose one or more materials with the lowest environmental impact [2]
- the material is generally a thermoformed material [1] and can be chosen from the group of materials consisting of:
- PVC polyvinyl chloride
- PCTFE polychlorotrifluoroethylene
- ACLAR TM ACLAR TM
- PE polyethylene
- HSL Hot Sealing Lacquer
- PVDC polyvinylidene chloride
- PET polyethylene terephthalate
- PET polyethylene terephthalate modified with glycol
- PET polyethylene terephthalate modified with glycol
- the reservoir may also include laminates, and in particular laminated sheets, of these materials.
- These components have beneficial chemical and / or moisture resistance characteristics.
- PCTFE, PVDC coated PVC or polypropylene is particularly suitable for the tank, and in particular the shell, due to its ability to act as a barrier to air and moisture.
- materials combining a laminated sheet of aluminum and HSL or, of aluminum and VMCH, are also preferred, in particular for providing the means of retention and / or separation.
- a material based on cellulose fibers (such as paper or cardboard) is an advantageous alternative to these materials from an environmental point of view and which can be considered. This material can in particular be combined with films, such as plastic films and in particular a film in one of the aforementioned thermoformed materials.

- the means for contacting the compound (e.g. a liquid) and the separator may include the selection of the material which allows a rupture, preferably a rupture provided at a particular point or a particular area of the reservoir, due to the application. by the user with sufficient pressure on part of the tank. This is the case with blisters for medicinal tablets where the application of pressure on the shell of the blister pack, and its deformation, causes the rupture of the film closing the receptacle, which is less resistant, and the making available of the seal [ cf. 5-9].
- This arrangement may well be suitable for the device according to the invention, the liquids being incompressible.
- the means making it possible to bring the compound and the diffusion layer into fluid contact can comprise piercing means, optionally comprising at least one element having a cutting or pointed end.
- these piercing means can, for example, take the form of needles, blades, protuberance or points.

- the means of bringing the compound into contact with the separator can be the simple juxtaposition and / or direct contact of at least part of the separator with the reservoir and more particularly with a rupture zone thereof, when she exists.
- the separator is advantageously configured to include a part extending beyond the electrodes (that is to say the anode and the cathode) and coming to be positioned opposite the rupture zone (provided) of the tank.
- the separator can be a diffusion or migration layer. It can be a simple space between the anode and the cathode, a space intended to be filled with a compound capable of triggering the production and / or storage of electrical energy. It can also be integrated or separate from the surface of one or more electrodes.
- the separator comprises, or is essentially constituted by, a material suitable for an electrolyte support function. This material includes woven or non-woven fibers (cotton, nylon, polyesters, glass), ceramics and natural substances (rubber, asbestos, wood).
- porous membrane more particularly made of cellulose fiber, such as a sheet of paper and in particular porous paper of the blotter or filter type.
- the basis weight of this paper can be advantageously chosen in the range going from 10 to 300 gm 2 , preferably from 50 to 150 gm 2 .

Thus a thickness of 2mm to 10 ⁇ m, in particular 1mm to 10 ⁇ m, preferably 300 to 150 ⁇ m (eg 190 ⁇ m) can be used. Thus, a 97 gm 2 grammage paper which constitutes the separator, is sandwiched between the two electrodes.
- the separator can include a single or multiple layers / sheets of material.
- the reservoir of the device can comprise one or more compartments. As will be described below, these compartments can comprise identical contents or different from each other. However, it is particularly advantageous to use this configuration to make it possible to release individual doses of compounds or to prepare a composition comprising a mixture of components which are unstable over time.
- the device comprises at least one other reservoir, this other reservoir comprising said compound capable of triggering production and / or storage of electrical energy or another compound capable, or not, of trigger the production and / or storage of electrical energy.

- An external pressure exerted on the shell 12 allows the latter to deform in order to release the contents of the reservoir 10.
- This pressure can be exerted by a user or by automated, hydraulic or pneumatic pressure means.
- Figure 3 schematically illustrates a first variant of a tank 110 with two compartments 112 and 113 and Figure 4 a second variant of a tank 210 with three compartments 212, 213 and 216.
- the various compartments can comprise in particular a solvent (for example water), electrolytes, enzymes, mediators, cofactors, a substrate (eg glucose) or molecules of enzymatic orientation.
- the retention means 14 may be, or include, a seal 16.
- the reservoir comprises two distinct spaces, each comprising several compartments.
- FIG. 5 illustrates a first variant of the device according to the invention in which two reservoirs 10a and 10b are used. Again, these can be the types of tanks described above.
- the reservoir 10a comprises a seal 16 capable of being ruptured and liquid 28.
- the reservoir 10b is located on the other side of the stack and comprises piercing means located outside the chamber of the reservoir 10b and allowing the seal to be pierced. 16.
- the reservoir 10b does not include liquid 28.
- the diffusion means 8 extends from a reservoir 10a to the reservoir 10b and is in contact with both.
- Steps 5A to 5C correspond to steps 1 A to 1 D described above with release of a liquid 28 in diffusion layer 8 and production of electricity according to a re-activatable regime.
- the electric power generation device 2 can be activated by exerting pressure on the reservoir 10A which breaks a seal 16 (as previously described).
- a reservoir 10 made by reusing a drug packaging was filled with approximately 250 ⁇ L of a glucose solution at a concentration of 150 mM in a solution.
- 0.1 M phosphate buffered saline Phosphate Buffered Saline, PBS, in English. It was then covered with a polyethylene film (Brand PARAFILM M) which is a plastic paraffin film on paper produced by the company Bemis North America, a company located in Neenah, Wisconsin (United States). It is a thermoplastic material (therefore it cannot be used in an autoclave), ductile, malleable, waterproof, odorless, cohesive and translucent. Reservoir 10 is then sealed with an adhesive strip to prevent any unwanted leakage of the glucose solution.
- FIGS. 1 and 2 After the electrodes 4 and 6 have dried, the device for producing electrical energy illustrated in FIGS. 1 and 2 is assembled as follows: A sheet of blotting paper of the Whatman filter paper type and of dimensions according to the configuration of the biopile with a thickness of 190 ⁇ m and a basis weight of 97 gm 2 which constitutes the diffusion layer 8, is sandwiched between the two electrodes 4 and 6. This layer of blotting paper comprises a projection 5. A sheet of GDL type graphite ( Gas Diffusion Layer) constituting a conductive layer 20 is positioned on the face of the anode 4 which is not that in contact with the diffusion layer 8.
- GDL type graphite Gas Diffusion Layer
- a conductive and gas diffusion layer 22 also made of a graphite sheet is placed in contact with the cathode 6 (on the opposite side of the face of the cathode 6 in contact with the diffusion layer 8).
- the latter allows the supply of oxygen to the cathode 6.
- It also constitutes a conductive layer.
- the gas is diffused by a hollow path allowing the gas to pass.
- the gas diffusion layer 22 and the cathode 6 are dimensioned and arranged so as to place the retention means 14 of the reservoir 10 directly opposite the diffusion layer 8 in order to allow the diffusion of the gas. content of the reservoir 10 in the diffusion layer 8, when the retention means 14 is pierced.
- drilling means 20 conductive layer
