Patent ID: 7879507

Claim:
An electrochemical cassette comprising, at least one electrochemical cell which comprises a membrane electrode assembly (MEA), a reductant flow field, an oxidant flow field, and a separator plate, at least one reductant external manifold and at least one oxidant external manifold, wherein each flow field comprises at least one opening extending through the periphery of the cell and each external manifold comprises a primary manifold and at least one port in fluid contact with the peripheral openings in the flow field to which the external manifold is intended to deliver material, wherein one or more MEA, oxidant flow field, reductant flow field, and separator plate, are assembled and encapsulated about the periphery thereof by a sealant; and wherein each external manifold includes a portion of the sealant having a negative impression of a manifold insert defining a volume at least partially bounded by the sealant and wherein the volume is in contact with the peripheral openings in the flow field to which the external manifold is intended to deliver material.
