Abstract: Systems and methods are provided for operating molten carbonate fuel cells to produce increased amounts of H2 in the anode effluent while still maintaining operation of the cell within conventional operation boundaries, such as having a temperature differential between the cathode input flow and the cathode effluent of 35° C. or more, with the cathode effluent being hotter than the cathode input flow. This temperature differential between the cathode input flow and the cathode effluent while still producing excess hydrogen is achieved in part by a) passing an input flow containing hydrocarbons and/or reformable fuel into an external reformer, b) reforming 20 vol % or more of the hydrocarbons and/or reformable fuel in the external reformer prior to c) passing the partially reformed input flow into a fuel cell or fuel cell stack where additional reforming is performed in the anode(s) and/or in a reforming element in the fuel cell stack.

Abstract: Systems and methods are provided for using molten carbonate fuel cells (MCFCs) to reduce, minimize, and/or avoid CO2 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 CO2. The high fuel utilization conditions can allow for mitigation of CO2 over extended periods of time in spite of the challenges of performing CO2 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.

Abstract: A module assembly is provided including a fuel cell stack assembly, a heat exchanger, and a housing enclosing the fuel cell stack assembly and the heat exchanger. The heat exchanger is configured to receive process gas from an external source and output said process gas to the fuel cell stack assembly, and configured to receive process gas from the fuel cell stack assembly and output said process gas. A fuel cell power plant is provided including a module assembly with a first end, a racking structure configured to hold the module assembly, balance of plant equipment, and ducting configured to provide fluid communication between the balance of plant equipment and the first end of the module assembly. The module assembly and the racking structure are configured such that the module assembly may be removed from the racking structure in a direction away from the first end of the module assembly.
