Disclosed is an anode for a molten carbonate fuel cell (MCFC) having improved creep property by adding an additive for imparting creep resistance to nickel-aluminum alloy and nickel as materials for an anode. Improved sintering property, creep property and increased mechanical strength of a molten carbonate fuel cell may be obtained accordingly.

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.

In various aspects, systems and methods are provided for integration of molten carbonate fuel cells with a Fischer-Tropsch synthesis process. The molten carbonate fuel cells can be integrated with a Fischer-Tropsch synthesis process in various manners, including providing synthesis gas for use in producing hydrocarbonaceous carbons. Additionally, integration of molten carbonate fuel cells with a Fischer-Tropsch synthesis process can facilitate further processing of vent streams or secondary product streams generated during the synthesis process.

The invention relates to a method, an electrolyte membrane, and a corresponding electrolysis cell or an electrolysis stack for producing hydrogen and oxygen from water vapor using electric energy and/or a corresponding fuel cell or a fuel cell stack in order to produce electric energy using hydrogen and oxygen by means of a redox reaction of lithiated iron oxide iron which is dissolved in a liquid alkali carbonate salt. The membrane for splitting water vapor into hydrogen and oxygen consists, in the embodiment according to the invention, of a novel lithiated iron oxide electrolyte which is dissolved in a liquid alkali carbonate salt mixture, generally also referred to as a carbonate melt, which includes lithium carbonate among others. The electrolyte and the liquid carbonate salt are bonded in a heat-resistant non-conductive matrix, for example consisting of lithium aluminate LiAlO.sub.2 and/or another heat-resistant material with a capillary effect.

Systems and methods are provided for using molten carbonate fuel cells (MCFCs) to reduce, minimize, and/or avoid CO.sub.2 emissions in a marine vessel environment. The systems and methods can include operation of MCFCs on a marine vessel under high fuel utilization conditions in order to provide power and capture CO.sub.2. The high fuel utilization conditions can allow for mitigation of CO.sub.2 over extended periods of time in spite of the challenges of performing CO.sub.2 mitigation in a potentially isolated environment such as a marine vessel. Additionally, the high fuel utilization can also reduce or minimize exhaust of fuels, such as methane, to the environment.
