Abstract
A sealless, planar fuel cell stack system, including a continuous bottom plate, a first permeable or interconnect layer, a continuous cell, a second permeable or interconnect layer, a continuous top plate, a fuel supply member, and an oxidant gas supply member, is provided. The fuel cell system of the present invention does not require glass-based sealants to seal its planar components. In the present system, the continuous cell of the system is supported by the first permeable layer. The second permeable layer is supported by the continuous cell. The fuel supply member supplies fuel into the first permeable layer. The fuel supply member extends between an outer edge and a center region of the first permeable layer and allows distribution of the fuel in a radial fashion. Further, the fuel supply member is connected to an external fuel manifold adjacent the outer edge. The oxidant gas supply member supplies oxidant gas into the second permeable layer. The oxidant gas supply member extends between an outer edge and a center region of the second permeable layer and allows distribution of the oxidant gas in a radial fashion. The oxidant gas supply member is connected to an external oxidant gas manifold adjacent the outer edge.
