Self-Contained Aircraft Oxygen System. Volume III. Advanced Oxygen Concentrator Stack Development.

摘要

Recent advances in solid polymer electrolyte (SPE) oxygen concentrator cell technology in the areas of high temperature operating capability,improved anode catalyst,improved current collector materials,more sophisticated cooling techniques and improved freeze/thaw capability indicated potential weight savings for the self-contained aircraft oxygen system in the order of 80% in the concentrator stack and 63% in the oxygen concentrator system. An eleven-month developmental design and test effort was performed which encompassed cell evaluation,fabrication technique development,full size cell test, 4-cell buildup test,full-size 32-cell stack test,systems analysis,and definition of ancillary components required to support the advanced oxygen concentrator stack. The program resulted in a cell design which offers a 65% stack weight savings (46% on a subsystem basis). (Author)
