1. 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.
