摘要： In a hydrocarbon fueled reformed gas fuel cell system having a rated power, a process for cooling reformed gas from a fuel processor prior to feeding the reformed gas to a shift converter includes the steps of providing a cooling zone having a hot gas inlet, a cooled gas outlet and a water inlet, feeding the reformed gas at a temperature of between 600 to 900° F. to the hot gas inlet, redirecting the reformed gas in the cooling zone so as to provide a swirling recirculating flow of the reformed gas in the cooling zone, atomizing water into droplets and contacting the droplets with the redirected reformed gas so as to cool the reformed gas and vaporize the water, and removing a stream of cooled reformed gas from the cooling zone wherein the reformed gas is at a temperature between 400 to 500° F. and the stream is substantially free of water droplets.

摘要： A keep warm system for a fuel cell, power plant (10), typically of the PEM type, prevents freeze-sensitive portions of the power plant, such as the cell stack assembly (CSA) (12) and the water management system (28, 30), from freezing under extreme cold external temperatures, during extended storage (CSA shut-down) periods. Pre-stored and pressurized fuel, typically hydrogen (25), normally used to fuel the anode (16) of the CSA, is used as fuel for a catalytic oxidation reaction at a catalytic burner (66) to produce heated gas that convectively passes in heat exchange relation with the freeze sensitive portions (12, 28, 30) of the power plant (10). The convective flow of the heated gases induces the air flow to the burner (66), obviating the need for parasitic electrical loads. Thermal insulating means (64) substantially enclose the freeze-sensitive CSA (12) and/or the water management system (28, 30), and the convective flow of the heated gas from the catalytic burner (66), to improve system thermal efficiency.

摘要： A burner assembly includes a catalyzed burner for combusting an anode exhaust stream from a polymer electrolyte membrane (PEM) fuel cell power plant. The catalysts coated onto the burner can be platinum, rhodium, or mixtures thereof. The burner includes open cells which are formed by a lattice, which cells communicate with each other throughout the entire catalyzed burner. Heat produced by combustion of hydrogen in the anode exhaust stream is used to produce steam for use in a steam reformer in the PEM fuel cell assembly. The catalyzed burner has a high surface area wherein about 70–90% of the volume of the burner is preferably open cells, and the burner has a low pressure drop of about two to three inches water from the anode exhaust stream inlet to the anode exhaust stream outlet. The burner assembly operates at essentially ambient pressure and at a temperature of up to about 1,700° F. (927° C.). The burner assembly can combust anode exhaust during normal operation of the fuel cell assembly. The burner assembly also includes an adjunct burner which can combust gasoline or anode bypass gas (the latter of which is a reformed fuel gas which is tapped off of the fuel cell stack fuel inlet line) during startup of the fuel cell power plant. Once start up of the fuel cell power plant is achieved, the burner assembly will need only combustion of the anode exhaust by the catalytic burner to produce steam for the reformer.
摘要翻译：燃烧器组件包括用于燃烧来自聚合物电解质膜（PEM）燃料电池发电厂的阳极废气流的催化燃烧器。涂覆在燃烧器上的催化剂可以是铂，铑或其混合物。燃烧器包括由格子形成的开孔，该细胞在整个催化燃烧器中彼此连通。用阳极排气流中的氢燃烧产生的热量用于生产用于PEM燃料电池组件中的蒸汽重整器中的蒸汽。催化燃烧器具有高的表面积，其中约70-90％的燃烧器的体积优选为开孔，并且燃烧器具有从阳极排气流入口至阳极排气口约2至3英寸水的低压降流出口。燃烧器组件在基本环境压力下工作，温度高达约1,700°F（927℃）。在燃料电池组件的正常操作期间，燃烧器组件可以燃烧阳极排气。燃烧器组件还包括辅助燃烧器，其可在燃料电池发电厂启动期间燃烧汽油或阳极旁路气体（其中后者是燃料电池堆燃料入口管路中的重新燃烧的燃料气体）。一旦实现燃料电池发电厂的启动，燃烧器组件将仅需要通过催化燃烧器的阳极排气的燃烧，以产生用于重整器的蒸汽。
