Claim 0:
1. A water electrolysis and cryogenic hydrogen liquefaction system, comprising:
a water stream in fluid communication with an anode side chamber of an electrolyzer; the electrolyzer comprising the anode side chamber, a cathode side chamber, and an electrolyzer membrane and electrode assembly located between the anode side chamber and the cathode side chamber;
a deep space oxygen radiator in fluid communication with the anode side chamber of the electrolyzer via a separated oxygen stream;
a cryogenic heat exchanger comprising an oxygen storage tank in fluid communication with the deep space oxygen radiator via a cooled oxygen stream;
an electrochemical hydrogen compressor in fluid communication with the cathode side chamber via a separated hydrogen stream;
a hydrogen storage tank in fluid communication with the electrochemical hydrogen compressor via a cooled hydrogen stream that is cooled by at least one recuperative heat exchanger and at least one deep space hydrogen radiator;
wherein at least a portion of the cooled hydrogen stream is in a first fluid communication with an expansion valve and the cryogenic heat exchanger that is located downstream of the expansion valve;
wherein the hydrogen storage tank is in a second fluid communication with the electrochemical hydrogen compressor via a warmed hydrogen stream that is warmed by the at least one recuperative heat exchanger; and
wherein the cryogenic heat exchanger is in fluid communication with the warmed hydrogen stream via a heat-exchanged hydrogen stream.
