A survey of oxygen generators for spacecraft based on water electrolysis is presented. The water electrolysis cells surveyed are predominantly prototype units including both liquid and vapor feed cells. Cell design, operational performance, gas purity, and problems encountered during testing are discussed. Suggestions are given as to where future research might be concentrated in order to solve some of the more general problems associated with water electrolysis.
