Claim 0:
1. An electrochemical compressor system comprising:
a) an electrochemical compressor comprising:
i) an anode;
ii) a cathode,
iii) an anisotropic anion conducting layer between and in contact with the anode and cathode and comprising an anion conducting polymer;

wherein the anion conducting polymer comprises a backbone selected from the group consisting of: poly(arylene), poly(phenylene) and poly(styrene);
wherein the anisotropic anion conducting layer has a concentration gradient of the functional groups from the anode to the cathode of at least 1.5:1;
b) a working fluid;
c) a power supply coupled electrically with the anode and cathode to produce a voltage potential across the anode and cathode;
wherein the voltage potential at the anode produces hydroxyl ions and wherein the voltage potential at the cathode consumes hydroxyl ions to create a pH gradient to transfer the working fluid from the anode to the cathode;
wherein the working fluid comprises carbon dioxide;
wherein the carbon dioxide is in equilibrium with bicarbonate ions and wherein the bicarbonate ions are transported through the anion conducting layer from the anode to the cathode and reformed into carbon dioxide at the cathode.
