    • A fuel system for an energy conversion device includes a deoxygenator system with an oxygen permeable membrane having a textured surface. A sweep gas and/or vacuum maintains an oxygen concentration differential across the membrane to deoxygenate the fuel. The textured surface increases the surface area of the oxygen permeable membrane. The textured surface of the oxygen permeable membrane is fabricated by pressing the textured surface into the oxygen permeable membrane with a microreplication-based tooling system. Another fabrication method presses the textured surface into a sacrificial film and the oxygen permeable membrane is then formed upon the sacrificial film to transfer the textured surface to the oxygen permeable membrane and the sacrificial film is then subsequently removed. Another fabrication method applies additional material to the oxygen permeable membrane through a porous sacrificial film.
    • 用于能量转换装置的燃料系统包括具有带纹理表面的透氧膜的脱氧器系统。 吹扫气体和/或真空保持跨膜的氧浓度差异以使燃料脱氧。 有纹理的表面增加透氧膜的表面积。 通过使用基于微复制的工具系统将有纹理的表面压入透氧膜来制造透氧膜的织构表面。 另一种制造方法将纹理化表面压入牺牲膜中,然后将氧透过膜形成在牺牲膜上以将纹理化表面转移到透氧膜上,然后随后除去牺牲膜。 另一种制造方法通过多孔牺牲膜将附加材料施加到透氧膜。
