    • A fuel cell system that employs a diode electrically coupled between bipolar plates in a fuel cell of a fuel cell stack for preventing the fuel cell between the plates from reversing its polarity. The diode is a thin-sheet p-n diode including doped semiconductor layers and has a thickness relative to the thickness of the MEA in the fuel cell so that the overall stack thickness does not increase. When the fuel cell is operating properly the diode does not conduct and all of the current through the fuel cell goes through the MEA. If the electric load on the stack increases to a level beyond the capability of the fuel cell, where the potential across the fuel cell goes significantly below zero, the diode will begin to conduct so that any current that cannot travel through the MEA with the cell voltage less than one negative forward diode voltage drop is able to go around the MEA through the diode.
    • 一种燃料电池系统,其采用电耦合在燃料电池堆的燃料电池中的双极板之间的二极管,用于防止板之间的燃料电池反转其极性。 二极管是包括掺杂半导体层的薄片p-n二极管,并且具有相对于燃料电池中的MEA的厚度的厚度,使得整个堆叠厚度不增加。 当燃料电池正常工作时,二极管不导通,并且通过燃料电池的电流全部通过MEA。 如果堆叠上的电负载增加到超过燃料电池能力的水平,其中燃料电池两端的电位明显低于零,则二极管将开始导通,使得任何不能通过MEA的电流流过电池 小于1负的正向二极管电压降可通过二极管绕过MEA。

    • Disclosed is an improved tow rope handle for attaching to a tow line. A bridle has two ends and a central loop for attaching the bridle to the tow line. A forward handle portion has two opposing forward sides and extends rearwardly therefrom to terminate at a central rear side. Each forward side is adapted for fixing with one end of the bridle. A rearward handle portion is fixed at a central forward side thereof with the central rear side of the forward handle portion, preferably with a rotational bearing axially aligned with a longitudinal axis of the forward handle portion. The rearward handle portion further includes two opposing handle grips extending laterally away therefrom. Each handle grip may terminate at a cap that includes a forward projecting stop. As such, a virtual stabilizing triangle is formed between each cap and the central attachment loop, but without bridle ropes that can interfere with or injure the user during use.
    • 公开了一种用于连接到牵引线的改进的牵引绳手柄。 桁架具有两个端部和用于将for绳连接到牵引线的中心环。 前手柄部分具有两个相对的前侧并从其向后延伸以终止在中央后侧。 每个前侧都适用于固定在襟翼的一端。 后把手部分与前手柄部分的中央后侧固定在其中心前侧,优选地具有与前手柄部分的纵向轴线轴向对齐的旋转轴承。 后把手部分还包括两个相对的手柄把手,其横向延伸离开。 每个手柄可以终止于包括向前突出的止挡件的盖子。 因此,在每个盖和中心附接环之间形成虚拟稳定三角形,但是在使用期间没有可能干扰或损坏使用者的绷绳。
