摘要： An example of a stable electrode structure is to use a gradient electrode that employs large platinum particle catalyst in the close proximity to the membrane supported on conventional carbon and small platinum particles in the section of the electrode closer to a GDL supported on a stabilized carbon. Some electrode parameters that contribute to electrode performance stability and reduced change in ECA are platinum-to-carbon ratio, size of platinum particles in various parts of the electrode, use of other stable catalysts instead of large particle size platinum (alloy, etc), depth of each gradient sublayer. Another example of a stable electrode structure is to use a mixture of platinum particle sizes on a carbon support, such as using platinum particles that may be 6 nanometers and 3 nanometers. A conductive support is typically one or more of the carbon blacks.
摘要翻译：稳定的电极结构的一个例子是使用梯度电极，该梯度电极在靠近常规碳上负载的膜和较小的铂颗粒附近使用较大的铂颗粒催化剂，该电极更靠近负载在稳定的碳上的GDL。有助于电极性能稳定性和ECA变化的一些电极参数是铂 - 碳比，电极各部分中铂颗粒的大小，使用其它稳定的催化剂代替大粒径的铂（合金等），每个梯度子层的深度。稳定的电极结构的另一实例是使用铂载体上的铂粒子的混合物，例如使用可能为6纳米和3纳米的铂颗粒。导电载体通常是一种或多种炭黑。

摘要： A fuel system for an energy conversion device includes a deoxygenator system with a porous membrane. The deoxygenator includes an oxygen receiving channel separated from the fuel channel by the porous membrane. The capillary forces counteract the pressure differential across the membrane, preventing any leakage of the fuel, while the oxygen concentration differential across the membrane allows for deoxygenation of the fuel through the porous membrane.

摘要： A system and method for warming a fuel cell on an aircraft, the system includes at least one fuel cell. The fuel cell includes an anode and a cathode for creating thermal and electrical energy. A temperature sensor measures a first temperature of the fuel cell. A control unit is coupled to the temperature sensor. The control unit increases the first temperature to a second temperature in response to the first temperature being at least equal to a selected temperature threshold. Increasing of the first temperature is indicative of the control unit operating in a warming mode. The second temperature is higher than the selected temperature threshold.

摘要： A power system for an aircraft includes a solid oxide fuel cell system which generates electric power for the aircraft and an exhaust stream; and a heat exchanger for transferring heat from the exhaust stream of the solid oxide fuel cell to a heat requiring system or component of the aircraft. The heat can be transferred to fuel for the primary engine of the aircraft. Further, the same fuel can be used to power both the primary engine and the SOFC. A heat exchanger is positioned to cool reformate before feeding to the fuel cell. SOFC exhaust is treated and used as inerting gas. Finally, oxidant to the SOFC can be obtained from the aircraft cabin, or exterior, or both.

摘要： A fuel system for an energy conversion device includes a deoxygenator system with a multitude of flow impingement elements which are interleaved to provide a fuel channel with intricate two-dimensional flow characteristics. The flow impingement elements break up the boundary layers and enhance the transport of oxygen from the core of the of the fuel flow within the fuel channel to the oxygen permeable membrane surfaces by directing the fuel flow in a direction normal to the oxygen permeable membrane. The rapid mixing of the relatively rich oxygen core of the fuel with the relatively oxygen-poor flow near the oxygen permeable membrane enhances the overall removal rate of oxygen from the fuel. Because this process can be accomplished in fuel channels of relatively larger flow areas while maintaining laminar flow, the pressure drop sustained is relatively low.
摘要翻译：用于能量转换装置的燃料系统包括具有多个流动冲击元件的脱氧器系统，其被交错以提供具有复杂二维流动特性的燃料通道。流动冲击元件通过沿着与透氧膜垂直的方向引导燃料流而分解边界层并增强氧从燃料通道内的燃料流的核心输送到氧气渗透膜表面。燃料的相对富氧核心与氧气渗透膜附近的相对贫氧流的快速混合提高了氧气从燃料中的总体去除速率。因为该过程可以在维持层流的同时在相对较大的流动区域的燃料通道中实现，所以压力下降相对较低。
