1. A solid-state compressor for electrochemically compressing a fluid, comprising:
a compressor cell stack, comprising at least one compressor cell having a membrane electrode assembly sandwiched between two cell plates,
an enclosure comprising two opposing and interconnected flanges, clamping the compressor cell stack at opposing sides thereof, and
two contact bodies, each of the two contact bodies interposed between the enclosure and a different one of two opposing sides of the compressor cell stack, and
two spaces, each of the two spaces enclosed between the enclosure and a respective contact body of the two contact bodies, each of the two spaces configured to contain a hydraulic fluid under pressure,
wherein a first space of the two spaces located on a first side of the opposing sides is hydraulically connected to a hydraulic fluid reservoir by means of a hydraulic fluid line;
wherein a second space of the two spaces located on a second side of the opposing sides is not hydraulically connected to the hydraulic fluid reservoir or the first space to maintain a passive pressure compensation system on the second side;
wherein the first side of the opposing sides is the cathode side of the membrane electrode assembly; and
wherein the two opposing flanges respectively grip around each of the two contact bodies, thereby entirely enclosing a first surface of a first contact body of the two contact bodies opposing a second surface of the first contact body of the two contact bodies contacting an outer surface of the compressor cell stack and a first surface of a second contact body of the two contact bodies opposing a second surface of the second contact body of the two contact bodies contacting the outer surface of the compressor cell stack.
