System and a method for manufacturing an electrolyte using electro deposition

1. A method of forming an electrolyte, comprising:

removably coupling a perimeter support to a temporary substrate;

electrodepositing a structural material and an electrolyte material to form an electrolyte composite film on said temporary substrate such that a perimeter of said film is supported by said perimeter support; and

electrodepositing a layer of ions on said electrolyte composite film.

2. The method of claim 1 , wherein said layer of ions comprises at least one of perfluorosulfonate ionomers or sulfonate polyetherketones.

3. The method of claim 1 , wherein said electrodepositing of said layer of ions comprises electrolytic deposition.

4. The method of claim 1 , wherein electrodepositing said layer of ions seals said electrolyte composite film.

5. The method of claim 1 , wherein electrodepositing said electrolyte composite film comprises electrophoretic deposition and electrodepositing said layer of ions comprises electrolytic deposition.

6. A method of forming an electrolyte, comprising:

removably coupling a perimeter support to a temporary substrate; and

electrodepositing an electrolyte composite film on said temporary substrate such that a perimeter of said film is supported by said perimeter support;

wherein said electrolyte composite film and said perimeter support comprise an electrolyte assembly and farther comprising removing said electrolyte assembly as an integral unit from said temporary substrate.

7. The method of claim 6 , further comprising electrodepositing a layer of ions on said electrolyte composite film.

8. The method of claim 7 , wherein said layer of ions is thinner than said electrolyte composite film.

9. The method of claim 7 , wherein said layer of ions comprises part of said electrolyte assembly and is removable as part of said integral unit from said temporary substrate.

10. The method of claim 6 , wherein said electrolyte composite film conducts ions when moisture is present.

11. The method of claim 6 , further comprising forming a cathode and anode on opposite sides of said integral unit.

12. The method of claim 6 , wherein said electrodepositing is performed by placing said temporary substrate in a solution already comprising polymer units and attracting those polymer units to said temporary substrate using an electric field.

13. The method of claim 6 , wherein said electrolyte composite film comprises a structural material and an electrolyte material.

14. The method of claim 13 , wherein said electrolyte material comprises perfluorosulfonate ionomer particles.

15. The method of claim 13 , wherein said structural material comprises ceramic particles.

16. A method of forming a fuel cell electrolyte, comprising:

disposing a temporary substrate in a solution already comprising polymer units;

electrodepositing said polymer units on said temporary substrate so as to form said fuel cell electrolyte on said temporary substrate; and

electrodepositing a layer of ions on said electrolyte composite film, wherein said layer of ions is thinner than said fuel cell electrolyte.

17. The method of claim 16 , wherein said layer of ions comprises at least one of perfluorosulfonate ionomers or sulfonate polyetherketones.
