OG exemplary drawing
 
1. An environment control system that is coupled with an enclosure and comprises:
a) an oxygen control electrolyzer cell,
wherein the oxygen control electrolyzer cell comprises:
i) an ion exchange medium;
ii) an anode;
iii) a cathode;
wherein the anode and cathode are configured on opposing sides of the ion exchange medium;
wherein the oxygen control electrolyzer cell is an integral membrane electrode assembly (MEA) comprising:
a housing attached to said oxygen control electrolyzer cell;
an anode opening in the housing to provide a flow of air to the anode;
a cathode opening in the housing to provide a flow of air to the cathode;
b) a controller that is coupled with a power source and the oxygen control electrolyzer cell to control electrical potential across the anode and the cathode;
wherein an oxygen concentration within the enclosure is controlled by the oxygen control electrolyzer cell;
d) a conditioning chamber in fluid communication with the enclosure;
e) a humidity control chamber;
wherein the oxygen control electrolyzer cell is fluid communication with the conditioning chamber; and
f) a separator configured between the conditioning chamber and the humidity chamber;
wherein the separator comprises ionomer and is substantially air impermeable having no bulk flow of gas therethrough.
