Claim:
1. A water-vapor transfer unit for a fuel-cell system, the water-vapor transfer unit comprising: a plate-stack comprising: a plurality of dry-side headers extending along the stacking dimension, each of the plurality of dry-side headers defined by respective ones of the dry-side aperture group; a plurality of wet-side headers extending along the stacking dimension, each of the plurality of wet-side headers defined by respective ones of the wet-side aperture group; a dry-side integrated fluid conduit for flow of the dry-side fluid therethrough, the dry-side integrated fluid conduit defined by the dry-side face-seal group, the plurality of dry-side headers, and the dry-side flow channels; and a wet-side integrated fluid conduit for flow of the wet-side fluid therethrough, the wet-side integrated fluid conduit defined by the wet-side face-seal group, the plurality of wet-side headers, and the wet-side flow channels, wherein the dry-side fluid enters the dry-side integrated fluid conduit through a first dry-side face-seal of the dry-side face-seal group, travels through a first dry-side header of the plurality of dry-side headers along the stacking dimension, is generally distributed through the plurality of dry-side flow channels from the first dry-side header, travels through a second dry-side header of the plurality of dry-side headers along the stacking dimension, and exits through a second dry-side face-seal of the dry-side face-seal group, and wherein the wet-side fluid enters the wet-side integrated fluid conduit through a first wet-side face-seal of the wet-side face-seal group, travels through a first wet-side header of the plurality of wet-side headers along the stacking dimension, is generally distributed through the plurality of wet-side flow channels from the first wet-side header, travels through a second wet-side header of the plurality of wet-side headers along the stacking dimension, and exits through a second wet-side face-seal of the wet-side face-seal group.
