Abstract

An apparatus comprising: one or more cells, each cell comprising: a proton conductor region configured to conduct proton charge carriers; a electron conductor region configured to conduct electrons; a first electrode associated with one of the proton conductor region and the electron conductor region; and a second electrode associated with the other of the proton conductor region and the electron conductor region; a removable barrier layer that is impermeable to water vapor extending over and protecting the one or more cells from water vapor; and a buffer layer that is permeable to water vapor between the one or more cells and the barrier layer.

First claim

We claim:

1. An apparatus comprising:
one or more cells, each cell comprising: a proton conductor region, comprising graphene oxide, configured to conduct proton charge carriers;
a electron conductor region, comprising reduced graphene oxide, configured to conduct electrons;
a first electrode adjacent with one of the proton conductor region and the electron conductor region;
a second electrode adjacent with the other of the proton conductor region and the electron conductor region;
a removable barrier layer that is impermeable to water vapor extending over and protecting the one or more cells from water vapor; and
a buffer layer that is permeable to water vapor between the one or more cells and the barrier layer.

2. An apparatus as claimed in claim 1 , wherein the removable barrier layer is flexible.

3. An apparatus as claimed in claim 1 , further comprising:
a substrate supporting the one or more cells, wherein the removable barrier layer contacts the substrate and forms attractive interactions with at least the substrate and wherein the removable barrier layer contacts the buffer layer.

4. An apparatus as claimed in claim 3 , wherein the removable barrier layer attaches more strongly to the substrate than the buffer layer.

5. An apparatus as claimed in claim 3 , wherein the attractive interactions formed between the removable barrier layer and the substrate are reversible so to remove the barrier layer and reattach the barrier layer.

6. An apparatus as claimed in claim 3 , wherein the attractive interactions formed between the removable barrier layer and the substrate are disrupted by peeling the removable barrier layer from the substrate.

7. An apparatus as claimed in claim 3 , wherein the substrate is flexible.

8. An apparatus as claimed in claim 3 , wherein a substrate comprises a front side and a back side, wherein the front side supports the one or more cells and wherein the removable barrier layer extends over the one or more cells and wraps around the substrate to contact at least the back side of the substrate.

9. An apparatus as claimed in claim 1 , wherein the removable barrier layer comprises polydimethylsiloxane and wherein the buffer layer comprises polyethylene naphthalene.

10. An apparatus as claimed in claim 1 , wherein the buffer layer provides mechanical protection to one or more proton cells when the removable barrier layer is removed from the apparatus.

11. An apparatus as claimed in claim 1 , wherein the buffer layer is flexible.

12. An apparatus as claimed in claim 1 , wherein the buffer layer is meshed material.

13. An apparatus as claimed in claim 1 , wherein the buffer layer is hydrophobic and/or non-stick.

14. An apparatus as claimed in claim 1 , wherein the buffer layer is breathable textile.

15. An apparatus as claimed in claim 1 , wherein the proton conductor region is configured to conduct protons in the presence of water.

16. An apparatus as claimed in claim 1 , wherein the proton conductor region is formed using printed ink.

17. A battery comprising:
one or more battery cells, each battery cell comprising at least one of:
a proton conductor region, comprising graphene oxide, configured to conduct proton charge carriers;
a electron conductor region, comprising reduced graphene oxide, configured to conduct electrons;
a first electrode adjacent with one of the proton conductor region and the electron conductor region;
a second electrode adjacent with the other of the proton conductor region and the electron conductor region;
a removable barrier layer that is impermeable to water vapor extending over and protecting the one or more cells from water vapor; and
a buffer layer that is permeable to water vapor between the one or more cells and the barrier layer.

18. A battery as claim in claim 17 , wherein the battery is a portable energy storage device.
