Hydrogen-Based Electrochemical Energy Storage

Lin Simpson (Inventor)

Research output: Patent


An energy storage device providing high storage densities via hydrogen storage. The device includes a counter electrode, a storage electrode, and an ion conducting membrane positioned between the counter electrode and the storage electrode. The counter electrode is formed of one or more materials with an affinity for hydrogen and includes an exchange matrix for elements/materials selected fromthe non-noble materials that have an affinity for hydrogen. The storage electrode is loaded with hydrogen such as atomic or mono-hydrogen that is adsorbed by a hydrogen storage material such that the hydrogen may be stored with low chemical bonding. The hydrogen storage material is typically formed of a lightweight material such as carbon or boron with a network of passage-ways or intercalantsfor storing and conducting mono-hydrogen, protons, or the like. The hydrogen storage material may store at least ten percent by weight hydrogen at ambient temperature and pressure.
