Provided herein are fabricated ionic polymer-composite metal membranes and energy storage systems comprising the same. The energy storage systems are particularly suitable for solar powered, portable hydrogen fuel cells. The systems are capable of converting renewable energy, such as solar radiation, into electrical energy, which is used to perform water electrolysis to create and store hydrogen fuel. The system can then act as a fuel cell, converting the hydrogen fuel into electrical energy that can be used, for example, to charge a mobile device. The membranes are advantageously smaller and more efficient than prior art electrolyzer membranes. This is due to an advanced fabrication technique also described herein.

A proton conductor includes a coordination polymer having stoichiometrically metal ions, oxoanions, and proton coordinating molecules capable of undergoing protonation or deprotonation. The coordination polymer including coordination entities that are repeatedly coordinated to bond the coordination entities with one another. Each coordination entity is either a first coordination entity or a second coordination entity. The first coordination entity is one metal ion of the metal ions coordinated with either at least one oxoanion of the oxoanions or at least one proton coordinating molecule of the proton coordinating molecules. The second coordination entity is the metal ion coordinated with each of at least one oxoanion of the oxoanions and at least one proton coordinating molecule of the proton coordinating molecules. At least a part of the proton conductor is non-crystalline. The proton conductor has high ion conductivity at high temperature.
