ABSTRACT:
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.
