Abstract
The present disclosure provides a gas diffusion layer for a proton exchange membrane fuel cell. The gas diffusion layer is a graphene membrane, and graphene lamellae in the graphene membrane are arranged irregularly. The present disclosure further provides a preparation method for the gas diffusion layer, and the proton exchange membrane fuel cell including the gas diffusion layer.
Claims8
A gas diffusion layer for a proton exchange membrane fuel cell, comprising:
- a graphene membrane with graphene lamellae arranged irregularly.
A method of preparing a gas diffusion layer for a proton exchange membrane fuel cell, comprising:
- heating a graphene oxide solution while stirring and/or under ultrasonication to remove a solvent, thus obtaining a graphene oxide membrane including graphene oxide lamellae, wherein the graphene oxide lamellae in the graphene oxide membrane are arranged irregularly;
- and
- heating and reducing the graphene oxide membrane at a temperature not lower than 900° C., to obtain a graphene membrane including graphene lamellae, wherein the graphene lamellae in the graphene membrane are arranged irregularly.
