摘要： A flow field plate for a fuel cell includes features in the gas input area that enhance gas distribution to the flow field channels. The input area of the flow field plate directs gases from an input manifold to the flow field channels. The input area includes one or more input channels which are defined by input channel walls. One or more features are included within the input area to enhance the distribution of the gas to the flow field channels. The gas distribution enhancement features may provide support for a sealing element to reduce blockage of the channels and/or may provide a path for fluid communication between adjacent input channels.

摘要： Components that include catalyst layers used in membrane electrode assemblies (MEAs), and methods of making such components are described. The catalyst layers yield more uniform current distributions across the active area of the MEA during operation. The catalyst layers may have a uniform catalyst activity profile of a less active catalyst to achieve more uniform current density over the MEA active area. The catalyst layers may have a variable activity profile, such as an activity profile with a varying slope, to compensate for the inherent nonlinearities of catalyst utilization during operation of an electrochemical fuel cell. Desired variable catalyst activity profiles may be achieved, for example, by varying the catalyst loading across the MEA from inlet to outlet ports or by varying the surface area of the catalyst loading or by varying the surface area of the catalyst support elements.
摘要翻译：描述了包括用于膜电极组件（MEA）中的催化剂层的组件以及制造这些组件的方法。催化剂层在操作期间在MEA的有效区域上产生更均匀的电流分布。催化剂层可以具有较低活性催化剂的均匀催化剂活性曲线，以在MEA活性区域上实现更均匀的电流密度。催化剂层可以具有可变的活性分布，例如具有变化的斜率的活性分布，以补偿在电化学燃料电池操作期间催化剂利用的固有非线性。期望的可变催化剂活性分布可以例如通过改变从入口到出口端口的MEA上的催化剂负载或通过改变催化剂负载的表面积或改变催化剂载体元素的表面积来实现。
