    摘要: Systems and methods provide for the thermal management of a high temperature fuel cell. According to embodiments described herein, a non-reactant coolant is routed into a fuel cell from a compressor or a ram air source. The non-reactant coolant absorbs waste heat from the electrochemical reaction within the fuel cell. The heated coolant is discharged from the fuel cell and is vented to the surrounding environment or directed through a turbine. The energy recouped from the heated coolant by the turbine may be used to drive the compressor or a generator to create additional electricity and increase the efficiency of the fuel cell system. A portion of the heated coolant may be recycled into the non-reactant coolant entering the fuel cell to prevent thermal shock of the fuel cell.

    摘要: Methods and systems provide for the creation of power, water, and heat utilizing a fuel cell. According to embodiments described herein, fuel is provided to a fuel cell for the creation of power and a fuel byproduct. The fuel byproduct is routed to a byproduct separation phase of a power and water generation system, where water is separated from the fuel byproduct. The remaining mixture is reacted in a burner phase of the system to create additional heat that may be converted to mechanical energy and/or utilized with other processes within the system or outside of the system. According to other aspects, the separated water may be utilized within a biofuel production subsystem for the creation of biofuel to be used by the fuel cell.

    摘要: Apparatus, systems, and methods provide for the management of a high temperature electrolysis process. According to embodiments described herein, a fuel cell electrolyzer stack is utilized in an electrolysis process. One implementation includes the use of a solid oxide electrolyzer. Input voltage is cycled around a thermal neutral voltage such that the fuel cell electrolyzer stack cycles between operation in an exothermic mode and an endothermic mode. The waste heat generated by operation in the exothermic mode is used to support the endothermic operation. By cycling between operation modes, the temperature of the fuel cell electrolyzer stack may be controlled without the use of a cooling loop or recirculated reactant flow, and the efficiency of the electrolysis process is maximized.
