Definitions
- the invention relates to membranes made from sulfonated polyether ether ketones
- Per or partially fluorinated sulfonic acid group-bearing polymers are sufficiently known from the literature. Membranes made of these polymers that are suitable for electrochemical purposes should have good membrane stabilities, sufficient chemical stability under the operating conditions of fuel cells and electrolysers and high values for proton conductivity (AE Steck in Materials For Fuel Cell Systems I, Proc. Int. Symp. On New Materials for Fuel Cell Systems, O. Savadogo, PR Roberge, TN souroglu, Montreal 1 995, pp. 74-94).
- membranes made from these polymers are expensive due to the necessary fluorination steps for the monomer and are also difficult to process. With fluorinated materials e.g. thin membranes ( ⁇ 50 ⁇ m) cannot be produced or only with great effort, which makes water management in these membranes more difficult. The recycling of the polymers is difficult or even impossible due to the difficult handling of these substances, especially because of their poor solubility.
- the object of the present invention is therefore to make membranes from sulfonated
- the membranes according to the invention are an inexpensive and environmentally friendly replacement for membranes made of fluorinated materials.
- the present invention thus relates to membranes which are particularly suitable for use in polymer electrolyte fuel cells or electrolyzers containing a sulfonated aromatic polyether ether ketone of the general formula (I)
- the ion exchange equivalent (IEC) of the sulfonated polyether ether ketone is in the range from 1.35 to 1.95 mmol (-SO 3 H) / g (polymer), preferably in the range from 1.50 to 1.75 mmol (-SO 3 H) / g (polymer) and the membranes have a long-term stability of at least 1,000 hours at an operating voltage of 0.4 V to 1.1 V.
- the molecular weight of the polymer used is an important parameter.
- the sulfonation of the parent polymer and the associated conversion into a charge-bearing polyelectrolyte leads to partial de-cleavage (see Vollmert, Molecular Heterogeneties in Polymers and Association of Macromolecules, IUPAC Symposium Marienbad, Pure and Appl. Chem. 43, 1 83-205, 1 975 and M. Hoffmann, The interlocking of thread molecules and their influence on the properties of polymers, Prog. Colloid. Pol. Sei. .66, 73- 86, 1 979) of the polymer due to the mutual repulsion of the charge centers on the polymer backbone.
- the membranes according to the invention contain sulfonated polymers with a
- Molecular weight Mw in the range from 50,000 g / mol to 310,000 g / mol, preferably 1 000 000 to 240 000 g / mol (determined in NMP (N-methylpyrollidone), 0.05% lithium chloride additive, 60 ° C., PS calibration , Waters column by GPC). Molecular weights that are too small are manifested by insufficient mechanical properties of the membranes; too large molecular weights require large sulfonation
- the polymers used to produce the membranes according to the invention have, in the dry state, an elastic modulus (E modulus) greater than or equal to 1,300 N / mm 2 and an elongation at break in the dry state after four hours of storage in a climatic cabinet at 23 ° C. and 50% rel.
- E modulus elastic modulus
- the modulus of elasticity of the membranes When wet, the modulus of elasticity of the membranes must not drop below 1 00 N / mm 2 in order to ensure a minimum strength of the membrane or membrane electrode unit even when moistened.
- the degree of sulfonation means the proportion of sulfonated repeat units in relation to the total number of repeat units.
- the ion exchange equivalent (I.E.C) which is expressed in millimoles of sulfonic acid groups per gram of polymer, is proportional to this value.
- the reciprocal of the I.E.C. is called the equivalent weight and usually in grams
- Polymer indicated per mole of sulfonic acid groups The I.E.C. is calculated from the ratio of carbon to sulfur determined by elemental analysis.
- Polyetheretherketones which are suitable for the membranes according to the invention, have an ion exchange equivalent of the sulfonated polyetherketone
- the membrane swells strongly to be expected in contact with water. This swelling behavior severely affects the membrane-electrode assembly (strength mentioned in the wet state). If the degree of sulfonation is above the specified upper limit, the polymer synthesized in contact with water is not mechanically stable enough or is already completely or partially - especially at temperatures above
- the sulfonated polymers used for the membranes according to the invention measured in contact with pure water, have a proton conductivity of> 3x1 0 "3 S / cm, preferably> 2x1 0 " 2 S / cm, in particular up to 300 mS / cm, at room temperature.
- the solution is cooled again to 5 ° C. and slowly poured onto ice water.
- the product is washed sulfate-free with deionized water (test with BaCI 2 solution), dried in a vacuum drying cabinet and ground.
- the degree of sulfonation is calculated by elemental analysis from the carbon / sulfur ratio.
- the ground, dry polymer (particle size approx. 80 ⁇ m, water content ⁇ 0.5%) is quickly introduced into the appropriate amount of NMP and dissolved under inert gas at 80 ° C with intensive stirring, so that an approx. 1 8% solution is obtained .
- the hot solution is filtered through a polypropylene fleece with an average mesh size of 1 ⁇ m and knocked out on glass plates on the same day and dried overnight in a dust-free convection oven at 80 ° C under normal pressure. The films are removed dry from the glass plate.
- Life test sPEEK a membrane with a sulfonation degree of 50% and a thickness of 40 microns on 4300 h when operating with H 2/0 2 at 50 ° C, pressureless.
- the drop in performance at 2700 hours and 3330 hours is due to the fact that the gas supply failed twice when the test was carried out. After renewed gas supply, the fuel cell delivered the same output as before.
- the polyether ketones listed were measured using a fuel cell (operating conditions: cell temperature 45 ° C, normal pressure up to max. 0.2 bar overpressure, humidification on the air side, self-made electrode with 0.2-0.3 mg Pt / cm 2 ).
- Proton conductivity data and mechanical properties are measured in water at 23 ° C (proton conductivity measured with a 4-pole arrangement at a frequency between 30 and 3000 Hz, phase angle between -1 and + 1 Hz).
- the molecular weight data given in Table 2) apply.
- Pretreatment of the membrane to measure the proton conductivity soak at 40 ° C for 30 minutes in 5% nitric acid and then with distilled
- Pretreatment of the membrane to measure the mechanical properties soak at 40 ° C for 30 minutes in 5% nitric acid and then with dist. Wash water. At 23 ° C and 50% rel. Dry air humidity for 4 h and soak at 23 ° C for 30 minutes.
