Abstract

The present invention relates to a material for an electrochemical device, especially a fuel cell, an electrolyzer or a storage battery, comprising a matrix and activated boron nitride contained in the matrix.

Claims (16)

1. A method of manufacturing a material for an electrochemical device, the method comprising:

activating a quantity of boron nitride; and

inserting the activated boron nitride into a matrix such that the activated boron nitride is contained in the matrix, thereby forming the material for an electrochemical device.

2. The method as claimed in claim 1 , wherein the activated boron nitride is in the form of percolated grains.

3. The method as claimed in claim 1 , wherein the activated boron nitride is in the form of sintered grains.

4. The method as claimed in claim 1 , wherein the activated boron nitride is crystallized in a hexagonal form.

5. The method as claimed in claim 1 , wherein the activated boron nitride is turbostratic.

6. The method as claimed in claim 1 , wherein the matrix is a mineral matrix.

7. The method as claimed in claim 1 , wherein the matrix comprises at least one of an organic material and an inorganic material.

8. The method as claimed in claim 1 , wherein the activated boron nitride is present in the material in a mass proportion ranging from 5% to 100%.

9. The method of claim 1 , further comprising extruding a film from the matrix.

10. A method of manufacturing a proton-exchange membrane comprising a layer of the material manufactured via the method as claimed in claim 1 .

11. A method of manufacturing an electrode for an electrochemical device, the electrode being at least partially made of the material manufactured via the method as claimed in claim 1 .

12. The method as claimed in claim 8 , wherein the activated boron nitride is present in the material in a mass proportion of about 70%.

13. The method as claimed in claim 8 , wherein the activated boron nitride is present in the material in a mass proportion of about 80%.

14. The method as claimed in claim 8 , wherein the activated boron nitride is present in the material in a mass proportion of about 98%.
