Abstract

Hydrogen orbital replacement unit serial number 00002 of the oxygen generation assembly was exhibiting an increasingly anomalous low voltage condition in cell #1 of electrolysis cell stack serial number 00005. The hydrogen orbital replacement unit was removed on November 16, 2016, and the on-board spare hydrogen orbital replacement unit serial number 00003 installed to continue oxygen generation system operation. The removed orbital replacement unit was returned from the International Space Station to Collins Aerospace for test, teardown, and evaluation, and failure analysis.
