20120129079 | HIGH DIFFERENTIAL PRESSURE ELECTROCHEMICAL CELL COMPRISING A SPECIFIC MEMBRANE - The present invention pertains to a high differential pressure electrochemical cell which encompasses a high pressure chamber and a low pressure chamber, said chambers being separated by a membrane, the membrane being ion-conductive, in particular proton-conductive, and electrically insulating, the membrane having a first surface in the high pressure chamber and a second surface in the low pressure chamber, the first surface being provided with a first electrode, and the second surface being provided with a second electrode, the first and second electrodes being electroconductively connected to each other via an electric circuit, wherein the membrane comprises at least two ion-conductive layers, wherein at least one of said ion-conductive layers is electrically insulating and at least one of said ion-conductive layers is electrically conductive. The high differential pressure electrochemical cell preferably is an ionic gas compressor, an ionic gas decompressor, or a high pressure electrolyser. | 05-24-2012 |
