Abstract: The invention relates to a solid-state compressor for electrochemically compressing a fluid, including: a compressor cell stack, including at least one compressor cell having a membrane electrode assembly sandwiched between two cell plates, an enclosure, clamping the compressor cell stack at opposing sides thereof, and at least one contact body, interposed between the compressor cell stack and the enclosure and contacting an outer surface of the compressor cell stack, wherein a space is enclosed between the enclosure and the contact body, which space is configured to contain a hydraulic fluid under pressure. The invention further relates to a method for operating such a solid-state compressor.

Abstract: The present invention relates to a solid state hydrogen compressor, including at least one membrane fixed between two porous electrodes, together forming a membrane electrode assembly, a pair of cell plates or bipolar plates, between which the membrane electrode assembly is clamped, wherein the membrane has a larger area than the porous electrodes and protrudes outside an area of the porous electrodes; and the cell plates have a larger area than the membrane and protrude outside an area of the membrane two insulating gaskets each surrounding one of the porous electrodes covering the part of the membrane that protrudes outside the region of the electrodes and protruding outside the area of the membrane, further including a reinforcement layer, arranged between the insulating gaskets, outside the area of the electrodes.
