Abstract: A packaging structure, packaging material and a packaging method for a battery pack including multiple battery cell units, multiple conductive units and one or more packaging materials are provided. The conductive units are electrically connected to the battery cell units. The packaging material is filled to gaps between the battery cell units and tightly bonded to surfaces of the battery cell units. The battery pack has an integrated structure. Therefore, the battery cell units do not move relative to each other, and breaking of connections between the battery cell units and a conductive metal line or sheet can be avoided.

Abstract: Layered proton exchange membrane and method for preparing the same. The layered proton exchange membrane comprises an organic/inorganic composite membrane and at least one proton exchange membrane wherein the organic/inorganic composite membrane comprises inorganic proton conductors and an organic base polymer. The method comprises mixing inorganic proton conductors with an organic base polymer to form an organic/inorganic composite membrane, and combining the organic/inorganic composite membrane with at least one proton exchange membrane.
