摘要： A fuel cell assembly (20) has an extended operational life, in part, because of unique startup and shutdown procedures used for operating the fuel cell assembly. In disclosed examples, a purge gas mixture of hydrogen and nitrogen includes less than 2% hydrogen for selectively purging portions of the assembly during a startup or shutdown procedure. In a disclosed example, the hydrogen-nitrogen mixture contains less than 0.1% hydrogen.

摘要： A thermal priority fuel cell power plant includes a cell stack assembly for generating an electrical power output. The cell stack assembly includes an anode, a cathode, and a waste heat recovery loop. The anode is configured to receive a fuel, the cathode is configured to receive an oxidizer, and the cell stack assembly is configured to generate the electrical power output by electrochemically reacting the anode fuel and the cathode oxidizer in the presence of a catalyst. The waste heat recovery loop includes a coolant inlet conduit and a coolant outlet conduit, and is configured to remove waste heat generated from the electrochemical reaction. A waste heat recovery loop is thermally coupled to the cell stack assembly for managing the waste heat of the cell stack assembly and for supplying thermal power to a thermal load demand. The waste heat recovery loop includes a heat exchanger in heat exchange relationship with the coolant outlet conduit and the thermal load demand. A controller is operatively associated with the cell stack assembly and the waste heat recovery loop. The controller controls the operation of the cell stack assembly by adjusting a fuel cell power plant parameter responsive to the thermal load demand. In one aspect, the fuel cell power plant parameter is reactant utilization. In another aspect, the fuel cell power plant parameter is a temperature for a thermal management system accumulator.

摘要： The condenser heat exchanger includes a housing that provides a gaseous stream flowpath and a bottom wall. A gaseous stream contains acid. The housing has a fluid inlet configured to introduce a liquid, such as water. A coolant tube is disposed within the housing in the gaseous stream flowpath and provides a coolant path. Acid condenses on and falls from the coolant tube into a collection area that is provided at the bottom wall near the coolant tube. The collection area is configured to maintain storage of a predetermined amount of fluid that includes the liquid, which dilutes the condensed acid.

摘要： Fuel processing by a reformer (42) and a shift reactor (44) converts hydrocarbon feedstock (12) and steam (36) to hydrogen-rich reformate (11), such as for use in a fuel cell power plant (47). Some of the reformate is recycled through a restriction (18) to the inlet (15) of a feedstock pump (14), thereby increasing its pressure sufficiently to cause recycle flow through a hydrodesulfurizer (21) and the secondary inlet (26) of an ejector (28) driven by the steam (36). Recycle pressure (48) is maintained by steam pressure through a valve (34) regulated by a controller (17).
