Zusammenfassung: | An exemplary fuel cell device includes porous plates. Electrode assemblies (24) are adjacent the porous plates (22). Partially porous plates (26) are adjacent the electrode assemblies (24) on an opposite side from the porous plates (22). The porous plates have coolant channels (32) that are configured to carry a liquid coolant. The partially porous plates have flow field channels (40) on one side that are configured to permit a fluid in the flow field channels to contact the corresponding immediately adjacent electrode assembly (24). An opposite side of the partially porous plates have a non-porous surface (42) that is configured to isolate the partially porous plate from any liquid in the coolant channels (32) of an adjacent one of the porous plates (22). Any liquid in the partially porous plate is exclusively from a reaction at the corresponding immediately adjacent electrode assembly. |
