ELECTROCHEMICAL AMINE/NITRILE REDOX METHOD FOR AMBIENT HYDROGEN STORAGE

A method and system for releasably storing hydrogen and generating electricity including an electrochemical cell including a cathode, an anode, an electrolyte, a microporous separator, an electrical connection between the cathode and the anode, an amine source, a nitrile source, a hydrogen source, and an oxygen source, wherein the electrochemical cell is configured to be operated in a hydrogen storage mode, a hydrogen release mode, and electrical generation mode. The amine/nitrile redox couple provides for full cycle electrochemical conversion of hydrogen under mild conditions.
