Abstract:
An electrochemical cell, comprising:a. an electrolyte held within a porous non-conductive matrix having a first major surface and an opposed second major surface;b. an anode electrode supported in intimate contact with the first major surface and a cathode electrode supported in intimate contact with the second major surface; andc. at least one porous support plate including a contact bi-layer adjacent the anode or cathode electrode supported on a porous substrate layer, wherein the contact bi-layer includes hydrophobic phase means for facilitating gas transfer and for restricting liquid absorption through a network of hydrophobic gas passages integrated throughout the contact bi-layer and the contact bi-layer also includes hydrophilic phase means for facilitating liquid transfer through a network of hydrophilic liquid passages integrated throughout the contact bi-layer, and for increasing capacitance of the cell.
