    • A flow control valve for a fuel cell that has particular application for controlling the flow of cathode air through a cathode flow channel of the fuel cell. The valve includes an element that controls the flow through the flow channel in response to changes in the voltage potential of the fuel cell. The valve includes a shape memory alloy wire and a flow control element secured to both ends of the shape memory alloy wire. The ends of the wire are also coupled to the anode and cathode of the fuel cell. When no current is flowing through the wire, the flow control element holds the wire in a pre-strained condition. If the voltage generated by the fuel cell increases, the current passing through the wire will heat the wire and cause it to shrink or contract which forces the flow control element into the flow path.
    • 一种用于燃料电池的流量控制阀,其特别用于控制通过燃料电池的阴极流动通道的阴极空气的流动。 阀包括响应于燃料电池的电压电位的变化来控制通过流动通道的流动的元件。 阀包括形状记忆合金线和固定到形状记忆合金线的两端的流量控制元件。 导线的端部也耦合到燃料电池的阳极和阴极。 当没有电流流过电线时,流量控制元件将电线保持在预应变状态。 如果燃料电池产生的电压增加,则通过电线的电流将加热电线并使其收缩或收缩,这迫使流量控制元件进入流动路径。

    • A three-dimensional (3D) ordered polymer microstructure having a length, a width and a height and including a plurality of waveguides that can be formed utilizing a mask and collimated light. The plurality of waveguides includes a first waveguide having a first finite propagation distance extended along a first direction, a second waveguide having a second finite propagation distance extended along a second direction and a third waveguide having a third finite propagation distance extended along a third direction. Here, only one of the length, width and height of the 3D ordered polymer microstructure is limited by the first finite propagation distance of the first waveguide, the second finite propagation distance of the second waveguide and the third finite propagation distance of the third waveguide.

    • A method for creating or forming a functionally graded 3D ordered open-cellular microstructure, and a functionally graded 3D ordered open-cellular microstructure. In one embodiment, the functionally-graded three-dimensional ordered open-cellular microstructure includes a first three-dimensional interconnected pattern of polymer waveguides having a first three-dimensional pattern; a second three-dimensional interconnected pattern of polymer waveguides having a second three-dimensional pattern differing from the first three-dimensional pattern; and an interface connected with the first three-dimensional interconnected pattern of polymer waveguides and the second three-dimensional interconnected pattern of polymer waveguides. Here, the term “functionally graded” refers to a spatial variation in the physical microstructure—and thus the properties—through the thickness of the material.
