摘要： Molten carbonate fuel cell configurations are provided that allow introduction of an anode input gas flow on a side of the fuel cell that is adjacent to the entry side for the cathode input gas flow while allowing the anode and cathode to operate under co-current flow and/or counter-current flow conditions. Improved flow properties can be achieved within the anode or cathode during co-current flow or counter-current flow operation by diverting the input flow for the anode or cathode into an extended edge seal region (in an extended edge seal chamber) adjacent to the active area of the anode or cathode, and then using a baffle to provide sufficient pressure drop for even flow distribution of the anode input flow across the anode or cathode input flow across the cathode. A second baffle can be used to create a pressure drop at the anode or cathode exit.

摘要： Molten carbonate fuel cell structures are provided that include a structural mesh support layer at the interface between the surface of the cathode and the cathode current collector. The structural mesh layer can have a mesh open area of 25% to 45%. In addition to providing structural support, the structural mesh layer can reduce or minimize ohmic resistance at the interface between the cathode and the cathode current collector.

摘要： Molten carbonate fuel cell configurations are provided that allow for introduction of an anode input gas flow on a side of the fuel cell that is adjacent to the entry side for the cathode input gas flow while allowing the anode and cathode to operate under co-current flow and/or counter-current flow conditions. It has been discovered that improved flow properties can be achieved within the anode or cathode during co-current flow or counter-current flow operation by diverting the input flow for the anode or cathode into an extended edge seal region (in an extended edge seal chamber) adjacent to the active area of the anode or cathode, and then using a baffle to provide sufficient pressure drop for even flow distribution of the anode input flow across the anode or cathode input flow across the cathode. A second baffle can be used to create a pressure drop as the anode output flow or cathode output flow exits from the active area into a second extended edge seal region (in a second extended edge seal chamber) prior to leaving the fuel cell.

摘要： A solid oxide fuel cell (SOFC) system and method, the system including a power module configured to receive a fuel from a fuel conduit of the system, the power module including a fuel cell stack, a module conduit fluidly connecting the fuel conduit and the stack, and a fuel control valve (FCV) configured to control a flow rate of the fuel in the module conduit. The system also includes a first detector configured to detect a first Wobbe Index (WI) of the fuel in the fuel conduit, and a controller configured to control the FCV to change the fuel flow rate based on whether the detected first WI indicates a change in the composition of the fuel.

摘要： An end cell assembly for a fuel cell stack includes an end plate and at least two inactive anode parts disposed adjacent to the end plate. Each inactive anode part comprises a nickel foam anode disposed directly above an anode current collector and a separator sheet disposed 5 above the nickel foam anode.
