Abstract
An improved method of separating hydrogen gas entrained with a first aqueous electrolytic solution of a water electrolyser for producing said hydrogen and said oxygen gas entrained with a second aqueous electrolyte solution, said method comprising producing a first two-phase flow discharge of said hydrogen gas in said first solution; producing a second two-phase flow discharge of said oxygen gas in said second solution; feeding said first discharge to a first separation chamber having a portion defining a hydrogen chamber to effect separation of said hydrogen gas from said first discharge; feeding said second discharge to a second separation chamber having a portion defining an oxygen chamber to effect separation of said oxygen gas from said second discharge; collecting said hydrogen gas from said hydrogen chamber; collecting said oxygen gas from said oxygen chamber; collecting said first discharge; collecting said second discharge; the improvement wherein at least one of said first discharge is discharged into said hydrogen chamber and said discharge is discharged into said oxygen chamber.
