HIGH PRESSURE ELECTROCHEMICAL CELL

Disclosed are electrochemical cells and methods of use or operation. In one aspect there is disclosed a method for management of an electrochemical cell, the method comprising operating the electrochemical cell at an operational voltage that is below or about the thermoneutral voltage for an electrochemical reaction. In another aspect there is disclosed an electrochemical cell comprising electrodes, an electrolyte between the electrodes, and a catalyst applied to at least one of the electrodes to facilitate an electrochemical reaction at an operational voltage of the electrochemical cell that is below or about the thermoneutral voltage for the electrochemical reaction. Also disclosed are various catalysts for the electrochemical cell comprising mixtures of various catalytic materials and polytetrafluoroethylene (PTFE).
