  • Publication number: 20250062380
    Abstract: In various aspects, molten carbonate fuel cell configurations are provided that include a reforming catalyst and alkali traps integrated with one or more structures within the anode gas-collection volume. The purpose of the reforming catalyst is to reform methane (or some other reformable fuel) into hydrogen. In operation, alkali metals may migrate from the fuel cell electrolyte into the anode. Unless trapped, the alkali metals may deactivate the reforming catalyst. The alkali trap prolongs the operating life of reforming catalyst within the anode volume by capturing some portion of the alkali metal in the anode gas-collection volume. This reduces an amount of alkali metal that interacts with the reforming catalyst in the anode gas-collection volume. The prolonged life of the reforming catalyst prevents a decrease in catalyst activity.

  • Patent number: 11888199
    Abstract: An elevated target amount of electrolyte is used to initially fill a molten carbonate fuel cell that is operated under carbon capture conditions. The increased target electrolyte fill level can be achieved in part by adding additional electrolyte to the cathode collector prior to start of operation. The increased target electrolyte fill level can provide improved fuel cell performance and lifetime when operating a molten carbonate fuel cell at high current density with a low-CO2 content cathode input stream and/or when operating a molten carbonate fuel cell at high CO2 utilization.

  • Patent number: 11888187
    Abstract: Molten carbonate fuel cells (MCFCs) are operated to provide enhanced CO2 utilization. This can increase the effective amount of carbonate ion transport that is achieved. The enhanced CO2 utilization is enabled in part by operating an MCFC under conditions that cause transport of alternative ions across the electrolyte. The amount of alternative ion transport that occurs during enhanced CO2 utilization can be mitigated by using a more acidic electrolyte.

  • Publication number: 20230246215
    Abstract: Systems and methods are provided for improving the operation of molten carbonate fuel cells that include cathode current collector structures that have reduced contact area with the cathode in order to create increased cathode open surface area. Molten carbonate fuel cells that have cathode collectors with reduced contact area with the cathode can have an increased tendency to suffer structural difficulties during operation, such as formation of gaps between electrolyte and one or both electrodes. Use of a sintered anode in such a fuel cell can reduce or minimize the impact of such structural difficulties. The sintered anode can provide higher pore volume and/or a more stable pore structure and/or increased structural stability in a fuel cell that includes a cathode collector that has a reduced contact area with the cathode. This can maintain a more stable interface between the cathode and electrolyte and/or between the anode and the electrolyte.

  • Patent number: 11695122
    Abstract: A layered cathode structure for a molten carbonate fuel cell is provided, along with methods of forming a layered cathode and operating a fuel cell including a layered cathode. The layered cathode can include at least a first cathode layer and a second cathode layer. The first cathode layer can correspond to a layer that is adjacent to the molten carbonate electrolyte during operation, while the second cathode layer can correspond to a layer that is adjacent to the cathode collector of the fuel cell. The first cathode layer can be formed by sintering a layer that includes a conventional precursor material for forming a cathode, such as nickel particles. The second cathode layer can be formed by sintering a layer that includes a mixture of particles of a conventional precursor material and 1.0 vol % to 30 vol % of particles of a lithium pore-forming compound.
