A reinforced membrane, said reinforced membrane comprising: (i) a planar reinforcing component made from metal, carbon, polymer or a composite thereof, and (ii) an ion-conducting material, characterised in that the planar reinforcing component is a cellular structure, comprising a plurality of discrete cells, wherein the wall of each cell extends through the thickness of the component such that the cell wall is impermeable to the proton- conducting material and wherein the proton-conducting material fills the cells of the planar reinforcing component is disclosed. Such a membrane is of use in a fuel cell or an electrolyser. |
