Patent ID: 7374837

Claim:
An electrochemical cassette comprising at least one electrochemical cell which comprises: a liquid electrolyte flow field having at least one reactant manifold opening extending through the thickness thereof, at least one electrolyte manifold opening extending through the thickness thereof; a fuel flow field and an oxidant flow field, each component having at least one reactant manifold opening extending through the thickness thereof, at least one electrolyte manifold opening extending through the thickness thereof, and at least one sealant manifold opening extending through at least a portion of the thickness thereof, at least two gas permeable porous conductive electrodes having a catalyst deposited on a surface of each electrodes wherein the porous conductive electrodes are interposed between each of the oxidant flow field and the fuel flow field and the liquid electrolyte flow field such that the catalyst is in contact with the liquid electrolyte flow field; wherein the one or more liquid electrolyte flow field, the oxidant flow field, the fuel flow field, and the porous conductive electrodes are assembled and encapsulated about the periphery thereof by a sealant; and wherein the sealant contemporaneously seals the respective channels of the one or more liquid electrolyte flow field, the oxidant flow field, the fuel flow field, and the porous conductive electrodes to selectively block one or more ports in proximity thereto.
