Abstract
The determination of the hydrogen pressure equivalent to one amp hour of stored capacity has been conducted at various rates of charge and discharge and at different temperatures. Cell temperature control in this determination contrasts isothermal versus cold plate conditions. Selected regions of the hydrogen pressure plots are evaluated in terms of consistent cell pressure factors. Pressure factors determined on charge suggest a maximum coulombic efficiency of 96% to that obtained on discharge.
