摘要： A method for preparing a membrane to be assembled in a membrane,electrode assembly is disclosed comprising the step of swelling an ion-conducting membrane in a liquid containing at least one solvent or to an atmosphere containing the vapor phase of at least one solvent by controlling the content of the solvent in the ion conducting membrane. Further, a method for manufacturing a membrane electrode assembly using a ion conducting membrane is disclosed, comprising the steps of: providing a ion conducting membrane in a pre-swollen state; coating of the ion conducting membrane on both sides with an electrode layer to form a sandwich; and hot-pressing the sandwich to form an ion conducting bonding of the afore-mentioned layers of the sandwich. Furthermore, a membrane electrode assembly is disclosed comprising a hot pressed sandwich comprising an electrode layer, a ion conducting membrane and again an electrode layer, thereby using the ion conducting membrane in its pre-swollen status prior to the hot-pressing.

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： 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： A method for preparing a membrane to be assembled in a membrane electrode assembly (10) is disclosed, comprising the steps of : a) irradiating sections (4) of a polymer film (2) with electromagnetic and/or particle radiation with a predetermined irradiation profile in order to both define irradiated sections (4) and to form reactive centers, i.e. radicals, in said irradiated sections (4) of the membrane; thereby separating the irradiated sections (4) from each other by separation bands (6) of un-irradiated membrane sections; b) exposing the film (2) comprising the irradiated sections (4) to a monomer or a mixture of monomers amenable to radical polymerization in order to achieve the formation of a graft copolymer in said irradiated sections (4).

摘要： It is the objective of the present invention to provide a method for preparing a polymer membrane for a polymer electrolyte water electrolyser in 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, to anodic 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 insitu on the flight.

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 (
