With respect to the method, this objective is achieved according to the present invention by a method to remove non- proton cationic impurities from the ionomer comprised in a proton exchange membrane and the respective anode side and cathode side catalyst layer of an electrochemical cell, comprising the steps of: a) providing a supply path for an anode feed to the ionomer on the anode side of the proton exchange membrane; b) providing a supply path for a cathode feed to the ionomer on the cathode side of the proton exchange membrane; and c) bringing a regenerating fluid with acidic pH in contact to the ionomer on the cathode side of the proton exchange membrane to accomplish an ion exchange of the non-proton cationic impurities with protons and thus remove the non- proton cationic impurities from the ionomer into the regenerating fluid. These measures allow to remove the non-proton cationic impurities from the ionomer of the electrochemical cell without increasing the risk of corrosion and without an interruption of the process of the electrochemical cell.

摘要： The present invention has the objectives to provide an electrolyte membrane and a method for generating such an electrolyte membrane wherein the resistance of the electrolyte membrane should be as low as possible to minimize ohmic losses. Concurrently, the electrolyte membrane should have a low permeability for the redox- active species. If redox-active species are still crossing the electrolyte membrane, this transport should be balanced during charge and discharge in order to prevent a net vanadium flux and the associated capacity fading. Moreover, the electrolyte membrane should be mechanically robust, chemically stable in the respective electrolyte solution, and be of low cost. The present invention describes a family of ion exchange membranes comprising a bilayer architecture to achieve these requirements. The bilayer membrane comprises two polymers, i) a polymer comprising N-heterocycles with electron lone pairs acting as proton acceptor sites and ii) a mechanically robust polymer that acts as a support, which can be a dense cation exchange membrane or a porous support layer as shown in Figure 2. This bilayer architecture allows the use of a very thin (

摘要： It is the objective of the present invention to provide a membrane with high ion selectivity, high physicochemical stability and low cost is of vital importance. This objective is achieved according to the present invention by an ion exchange membrane with selective ion transport properties, in particular for use in a redox flow battery, comprising: a) a mechanically robust and chemically resistant base polymer film (matrix); b) ion exchange groups covalently bound to the polymer matrix, being anion exchange groups or cation exchange groups or a mixture thereof; c) blocking groups covalently bound to the polymer matrix preventing the passage of redox-active species across the membrane;and d) optionally additional functional constituents, such as crosslinkers or antioxidants; Therefore, this membrane has a highion selectivity, high physicochemical stability and low cost due to the selection of a base polymer film and the ion exchange groups as well as the blocking groups preventing the passage of redox-active species across the membrane. Preferably, the membrane is produced via radiation induced grafting, comprising the steps of: a) exposing the base polymer to ionizing radiation to introduce active sites; b) exposing the irradiated base polymer to a mixture of monomers comprising i) a monomer containing an ion exchange group or a precursor monomer yielding an ion exchange group in a subsequent step, ii) a monomer containing a functional group to block the passage of redox-active species through the membrane or a precursor monomer yielding the functional blocking group in a subsequent reaction step; iii) optional additional monomers, such as a crosslinker and antioxidant;and c) in case of the use of precursor monomers for ion exchange sites and blocking groups, post-treatment of the grafted film to introduce ion exchange sites and/or blocking groups is performed.

摘要： It is the goal of the present invention to provide a method and a plant for a most efficient operation of the industrial operation thereby storing the CO 2 generated by this industrial operation in a way that further processes benefit from the energy stored into the CO 2 separated from the industrial operation (wherein the CO 2 can be subjected to a conversion into another product, such as SNG). This goal is achieved according to the present invention by a method and a plant for storing CO2 stemming from an industrial process as synthetic or substitute natural gas, comprising : a) an industrial operation plant generating CO 2 comprised in a flue gas; said industrial operation plant performing an industrial combustion or calcination process or metallurgical process; b) a CO 2 separating unit for separating a CO 2 containing gas mixture from the flue gas; c) an electrolysis unit for splitting water by electrolysis to produce H2 and O 2 ; d) a methanation unit for converting the CO 2 containing gas mixture and the H 2 by a methanation reaction to a methane rich gas which can be used as or upgraded to synthetic natural gas. Therefore, the present invention forms an integrated process to combine the four steps (combustion and/or calcination of cement; CO 2 separation; electrolysis to produce H 2 and O 2 ; methanation) in a synergetic way to solve both problems described above with a significantly higher efficiency than possible in non-integrated plants.

摘要： A novel approach based on the increase of the intrinsic oxidative stability of uncrosslinked membranes is addressed. Hence, the co-grafting of styrene with methacrylonitrile (MAN), which possesses a protected α-position and strong dipolar pendant nitrile group, onto 25 μm ETFE base film is disclosed. Styrene / MAN co-grafted membranes were compared to styrene based membrane in durability tests in single H 2 /O 2 fuel cells. It is shown that the incorporation of MAN dramatically improves the chemical stability. The membrane preparation based on the copolymerization of styrene and MAN shows encouraging results and offers the opportunity of tuning the MAN and crosslinker content to enhance the oxidative stability of the resulting fuel cell membranes.

摘要： The present invention discloses a composite electrolyte membrane and a method to fabricate it. The composite electrolyte membrane is meant to be used in an electrochemical energy storage or conversion device, including but not limiting to redox flow batteries, fuel cells and electrolyzers. The composite electrolyte membrane is produced according to a method for laminating a polymer electrolyte film onto a porous support layer for generating a composite membrane for energy storage devices; comprising the following steps: a) placing the polymer electrolyte film on a first flat support plate; b) placing the porous support layer on the polymer electrolyte film; c) wetting the porous support layer with a first solution comprising a first solvent, which is a high boiling point solvent, used to partially solubilize the polymer electrolyte film allowing its solubilized fraction to flow into the pores of the porous support and a second solvent, which is a low boiling point solvent, to prevent excessive solubilization of the polymer electrolyte film, wherein the solubilized fraction of the polymer electrolyte film forms an interlocking interface with a superficial part of the porous support layer; d) placing a second flat support plate, preferably with two tissues to absorb solvent excess, on the wetted porous support layer to form a stack having sandwiched the polymer electrolyte film, the interlocking interface and the porous support layer between the first and the second flat support plates; e) hot-pressing the stack at an elevated temperature and an elevated pressure for a pre-defined amount of time; and f) cooling down the hot-pressed stack and removing the first and the second flat support plate to isolate the composite membrane comprising i) the polymer electrolyte film, ii) the now solidified and formerly solubilized fraction of the polymer electrolyte film penetrated into the pores of the porous support layer forming a solidified interlocking interface and iii) the porous support layer.

摘要： It is the objective of the present invention to provide a method for preparing a polymer membrane for a polymer electrolyte water electrolyserin order to achieve thin membranes with high crossover suppression and without showing a negative impact on the cell performance. This objective is achieved according to the present invention by a method to prepare an ionomer of an ion exchange membrane (anion or cation exchange) with a recombination catalyst to prevent gas crossover of species, such as hydrogen and/or oxygen,toanodic and cathodic cell compartments of an electrochemical cell; said method comprising the steps of: a) providing the ionomer as a proton or an anion exchange polymer; b) selecting the recombination catalyst from the precious metals group; c) providing the selected recombination catalyst in an ionic form being comprised in a liquid metal salt solution; d) immersing the ion exchange membrane into the liquid metal salt solution thereby exchanging at least a part of the ionic ionomer ports with the ionic form of the recombination catalyst; e) assembling the immersed ion exchange membrane in the electrochemical cell; and f) at least partially reducing the content of the ionic form of the recombination catalyst into the metallic form by forcing hydrogen to permeate through the ionomer of the ion exchange membrane. Therefore, the present invention presents a new reduction method for Pt-Ions by diffusing hydrogen through the PEM in a PEWE cell. The presented solution provides a way to achieve thin membranes with high crossover suppression, without a negative impact on the cell performance and a reduction in-situ on the flight.
