Abstract
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.
Claims9
A method of operating an electrochemical cell to releasably store hydrogen, the electrochemical cell comprising a cathode, an anode, a microporous separator, an electrolyte, and the method comprising:
- hydrogenating a nitrile to releasably store hydrogen by:
- feeding hydrogen to the anode;
- feeding the nitrile to the cathode;
- and
- applying a hydrogenation cell voltage to the electrochemical cell such that the hydrogen is oxidized via a hydrogen oxidation reaction at the anode and consumed to hydrogenate the nitrile to thereby store the hydrogen in a hydrogenation product amine.
