双极板/集流体在直接甲醇燃料电池（DMFC）中起着重要作用。具有不同几何形状的集流体可对电池性能具有显著影响。本文介绍了分形几何在直接甲醇燃料电池（DMFC）集流体设计中的应用。这种新的集电器设计被命名为CCFG（分形几何集电器）。本研究确定了如何对印刷电路板直接甲醇燃料电池集流体进行更好的自由开放设计。结果表明，双极板上的自由面积比和总孔周长都对电池性能有影响。周长上的孔的总数呈现出比自由开口率更大的影响。使用阴极集电器比使用阳极集电器的电池性能更敏感。
The bipolar plate/current collector plays an important role in direct methanol fuel cells (DMFC). A current collector with different geometries could have a significant influence on cell performance. This paper presents fractal geometry application to current collector design in a direct methanol fuel cell (DMFC). This new current collector design is named CCFG (Current Collectors with Fractal Geometry). This research determined how to make a better free open design for the current collector on a printed circuit board based DMFC. The results show that both the free area ratio and total holes perimeter length on the bipolar plate affect the cell performance. The total number of holes on the perimeter presents greater effects than the free open ratio. The cell performance is more sensitive using a cathode current collector than the anode current collector.
