Molten carbonate fuel cell configurations are provided that allow for introduction of an anode input gas stream on a side of the fuel cell adjacent an inlet side of a cathode input gas stream while allowing the anode and cathode to operate under parallel and/or counter flow conditions. A uniform flow distribution across the anode or the cathode is achieved by diverting an input flow of the anode or the cathode into an extended edge sealing region adjacent to an active region of the anode or the cathode, and then using a baffle to provide a sufficient pressure drop, improved flow characteristics are achieved during parallel flow or counter flow operation. A second baffle may be used to create a pressure drop when an output flow exits from the active region into a second extended edge sealing region prior to exiting the fuel cell. 提供了熔融碳酸盐燃料电池单元配置，其允许在燃料电池单元的邻近阴极输入气流的入口侧的一侧上引入阳极输入气流，同时允许阳极和阴极在并向流和/或对向流条件下操作。通过将所述阳极或所述阴极的输入流转向到邻近所述阳极或所述阴极的活性区域的延伸边缘密封区域中，并且然后使用挡板来提供足够的压降，以实现跨所述阳极或所述阴极的均匀流分布，在并向流或对向流操作期间实现改进的流特性。当
