Abstract

A process for manufacturing a reinforced membrane-seal assembly includes: (i) providing a carrier material; (ii) providing a planar reinforcing component having one or more first regions including pores and a second region including pores, the first regions being patches and non-continuous and the second region surrounding the first regions and being continuous; (iii) depositing an ion-conducting component; (iv) drying the ion-conducting component; (v) depositing a seal component; (vi) drying the seal component (vii) removing the carrier material. In embodiments, ion-conducting component fills the pores in the first regions and seal component fills the pores in the second region; steps (ii), (iii) and (v) can be carried out in any order; step (iv) is carried out subsequent to step (iii); step (vi) is carried out subsequent to step (v); and steps (iv) and (vi) are carried out subsequent to step (ii). Also disclosed is an assembly prepared by such process.

Claims (16)

1. A process for the manufacture of a reinforced membrane-seal assembly, said process comprising the steps of:

(i) providing a carrier material onto which components comprising the reinforced membrane-seal assembly are applied;

(ii) providing a planar reinforcing component having one or more first regions comprising pores and a second region comprising pores, the first regions being patches and non-continuous and the second region surrounding the first regions and being continuous;

(iii) depositing an ion-conducting component as a liquid or dispersion;

(iv) drying the ion-conducting component;

(v) depositing a seal component as a liquid or dispersion wherein the seal component is non-ion-conducting;

(vi) drying the seal component

(vii) removing the carrier material; wherein ion-conducting component fills the pores in the first regions and seal component fills the pores in the second region and wherein steps (ii), (iii) and (v) can be carried out in any order, wherein step (iv) is carried out subsequent to step (iii) and wherein step (vi) is carried out subsequent to step (v) and wherein steps (iv) and (vi) are carried out subsequent to step (ii).

2. A process according to claim 1 , wherein steps (ii), (iii) and/or (v) are carried out more than once.

3. A process according to claim 1 , wherein steps (iv) and (vi) are carried simultaneously.

4. A process according to claim 1 , wherein the planar reinforcing component has more than one first region.

5. A process according to claim 4 , wherein the carrier material is provided as a roll-good product.

6. A process according to claim 4 , wherein the planar reinforcing component is provided as a roll-good product.

7. A continuous roll of multiple reinforced membrane-seal assemblies prepared by the process according to claim 4 .

8. A process according to claim 2 , wherein steps (iv) and (vi) are carried simultaneously.

9. A process according to claim 5 , wherein the planar reinforcing component is provided as a roll-good product.
