Abstract:
1. A fuel cell plate, comprising: a unitized plate including a plurality of first headers disposed at a first end of the plate, a plurality of second headers disposed at a second end of the plate, and a plurality of active regions formed thereon, an inlet aperture formed in each of the first headers, an outlet aperture formed in each of the second headers, each of the active regions including a flowfield disposed between one of the first headers and one of the second headers, and each of the flowfields in fluid communication with the inlet aperture of one of the first headers and the outlet aperture of one of the second headers, wherein the active regions are separated and electrically insulated from one another by at least one dielectric divider, the at least one dielectric divider disposed between an adjacent pair of the active regions and abutting an edge of each of the adjacent pair of the active regions, wherein the first headers are separated from one another by the at least one dielectric divider, wherein the second headers are separated from one another by the at least one dielectric divider, wherein the at least one dielectric divider includes an insulating strip, wherein each of the active regions is adapted to receive a dedicated supply of a reactant, wherein the inlet aperture of one of the first headers is adapted to selectively deliver the reactant to one of the active regions, and wherein the outlet aperture of one of the second headers is adapted to selectively exhaust the reactant from one of the active regions.
