Abstract
An electrochemical capacitor is prepared by assembling a stacked assembly of at least two bipolar electrodes, where each of the bipolar electrodes includes a metal foil electrode substrate having a porous, electronically conductive substrate coating, preferably porous platinum, on each surface. The stacked assembly further has a porous separator layer between each of the electrodes, made of a material that is electronically non-conductive. An ionic conductor electrolyte, preferably a polyoxometalate, that wets both the substrate coating and the separator layer at temperatures above the melting point of the solid ionic conductor electrolyte is provided, the ionic conductor electrolyte having a melting point above about 30.degree. C. The ionic conductor electrolyte is introduced into the stacked assembly, as by external infiltration with an optional applied pressure to assist the infiltration.
