    摘要： A process including: providing a cylindrical substrate rotating about the long axis; applying at least one coating layer with a direct writing applicator on the outer surface of the rotating substrate; and curing the resulting coated layer or layers. The use of a direct writing applicator provides precision in the dispensing of organic photoconductor coating layers with respect to line width and line thickness.

    摘要： A bipolar plate includes angled facets oriented to form V-shaped projections on the plate edge. Liquid leaving the reactant channels is drawn back into the V-shaped grooves of the projections, leaving no liquid to obstruct the channel exit openings. The bipolar plate includes one portion of the bipolar plate offset from another portion of the bipolar plate so as to expose the reactant channels. The liquid is drawn toward the end portions of the reactant channels by capillary forces, while the gas flows can exit near the beginning of the offset portion. A fuel cell stack includes angled facets that are rotated to lie in the plane of the bipolar plate edges. The edges are chamfered so the channel exit openings of the reactant channels are at the tip portions thereof, thus allowing the liquid to flow away from the channel exit openings and the gas to exit freely.

    摘要翻译： 双极板包括定向成在板边缘上形成V形突起的倾斜小平面。 离开反应物通道的液体被拉回到突起的V形槽中，没有液体阻碍通道出口。 双极板包括从双极板的另一部分偏移的双极板的一部分，以暴露反应物通道。 液体通过毛细管力被吸引到反应物通道的端部，而气体流可以在偏移部分的开始附近离开。 燃料电池堆包括旋转以位于双极板边缘的平面中的倾斜小平面。 边缘被倒角，使得反应物通道的通道出口开口处于其顶端部分，从而允许液体从通道出口开口和气体离开自由地流出。

    摘要： A fuel cell including a water blocking layer positioned between anode gas flow channels and a gas diffusion media. The blocking layer prevents water from propagating through the gas diffusion media layer and entering the anode flow channels, while allowing gas from the flow channels to flow through the diffusion media layer to the membrane. A water accumulation channel can be provided around the perimeter of the gas diffusion media layer where blocked water is accumulated, and allowed to expand during cell freezing. A porous capillary wick can be provided in the accumulation channel for wicking water to the inlet end of the flow channels where it is used to humidify the anode gas coming into the fuel cell. The wick can have a tapered configuration so that it has a larger diameter at the gas input end of the flow channels.

    摘要翻译： 一种燃料电池，包括位于阳极气体流动通道和气体扩散介质之间的阻水层。 阻挡层防止水通过气体扩散介质层传播并进入阳极流动通道，同时允许来自流动通道的气体流过扩散介质层至膜。 可以在气体扩散介质层的周边周围设置积聚通道，其中堵塞的水被积聚，并允许在细胞冷冻期间膨胀。 可以在积聚通道中提供多孔毛细管芯，用于将水吸收到流动通道的入口端，在那里用于加湿进入燃料电池的阳极气体。 芯可以具有锥形构造，使得其在流动通道的气体输入端处具有较大的直径。
