Experience in Development and Long-term Operation of Mir's System for Oxygen Generation by Electrolysis

The paper describes the design specifics of the system for oxygen generation by electrolysis Elektron and major results obtained in long-term operation of the system aboard space station Mir.

Operational data analysis makes possible to draw a conclusion that the system is capable to attain life parameters for at least 2 years with maintaining serviceability for no less than 8 years without attendance and unit replacement.

Based on flight operation the possibility of reducing power consumption by 10 per cent is proven.

System design updates are realized in the water electrolysis system intended for the Russian segment of the international space station.
