Beschreibung
Zusammenfassung:	A cryocooler is disclosed which includes a reservoir ( 11 ), an electrochemical cell or proton conductive membrane (PCM) compressor ( 12 ) coupled to a source of AC current, and a gas expander in the form of a pulse tube expander module ( 13 ). The compressor ( 12 ) includes a proton conductive membrane ( 17 ) positioned between a pair of electrically conductive electrodes ( 18 ) and ( 19 ). The pulse tube expander module 13 includes a regenerator ( 21 ), a pulse tube ( 22 ), and in inertance tube ( 23 ). The regenerator ( 21 ) has a heat rejection part or aftercooler ( 25 ) and a cooling part or cold heat exchanger ( 26 ). The pulse tube ( 22 ) includes a heat rejection portion or hot heat exchanger ( 27 ).
