    摘要： A coolant system is proposed for addressing temperature concerns during start-up and shut-down of a cell stack assembly. The coolant system comprises a coolant exhaust conduit in fluid communication with a coolant exhaust manifold and a coolant pump, the coolant exhaust conduit enabling transportation of exhausted coolant away from a coolant exhaust manifold. A coolant return conduit is provided to be in fluid communication with a coolant inlet manifold and a coolant pump, the coolant return conduit enabling transportation of the coolant to the coolant inlet manifold. The coolant system further includes a bypass conduit in fluid communication with the coolant exhaust conduit and the coolant return conduit, while a bleed valve is in fluid communication with the coolant exhaust conduit and a gaseous stream. Operation of the bleed valve enables venting of the coolant from the coolant channels, and through said bypass conduit.

    摘要： A cell stack assembly (102) coolant system comprises a coolant exhaust conduit (110) in fluid communication with a coolant exhaust manifold (108) and a coolant pump (112). A coolant inlet conduit (120) enables transportation of the coolant to the coolant inlet manifold. The coolant system further includes a bypass conduit (132) in fluid communication with the coolant exhaust manifold and the coolant inlet manifold, while a bleed valve (130) is in fluid communication with the coolant exhaust conduit and a source of gas. Operation of the bleed valve enables venting of the coolant from the coolant channels, and through a shut down conduit (124). An increased pressure differential between the coolant and reactant gases forces water out of the pores in the electrode substrates (107,109). An ejector (250) prevents air form inhibiting the pump. Pulsed air is blown (238,239,243,245) through the coolant channels to remove more water.

The system includes at least one fuel cell for producing electrical energy from the reducing and oxidant fluid streams; a thermal management system that directs flow of a cooling fluid for controlling temperature within the plant including a porous water transport plate adjacent and in direct fluid communication with a cathode catalyst of the fuel cell; a direct antifreeze solution passing through the water transport plate; and, fuel processing components secured in fluid communication with the thermal management system for processing a hydrocarbon fuel into the reducing fluid and for controlling a concentration of a direct antifreeze in the direct antifreeze solution. The fuel processing components may include a boiler that receives a portion of the direct antifreeze solution from the thermal management system; a steam separator that directs separated steam from the boiler to a reformer for reforming the hydrocarbon fuel to the reducing fluid, and that directs separated liquid direct antifreeze solution back to the thermal management system. A preferred direct antifreeze solution is an alkanetriol selected from the group consisting of glycerol, butanetriol, and pentanetriol.

    摘要： A method of imprinting a workpiece includes lasing the workpiece to create a depression or other opening, depositing a laser-fusible polymer material into the depression, and then lasing the material so as to fuse the material into the depression. Preferably, the laser-fusible polymer material is fusible in the near infrared spectrum. An alternate method for imprinting using colored powder paints includes an additional step of heating the workpiece to ensure thermosetting of the colored powder paint. Laser fusible materials having particular physical characteristics and compositions may be used to facilitate the process.
