Ukusetshenziswa Kwemikhiqizo
Ivamise ukugoqwa kusuka ku-alloy futhi ingenziwa ibe i-diaphragm (ebizwa ngokuthi ifilimu) kanye neshubhu le-membrane (elibizwa ngokuthi ishubhu). Ugqinsi lwefilimu luvamise ukuba ngama-microns angama-50 kuye kwayi-100. Isetshenziselwa ikakhulukazi ukuhlanzwa komoya-mpilo, futhi umgomo wayo imodi yokusabalalisa isixazululo, futhi amandla okushayela okusabalalisa umehluko wengcindezi ye-hydrogen ezinhlangothini zombili zolwelwesi. Ku-300-500C, lapho i-hydrogen impahla eluhlaza icindezelwa ohlangothini olulodwa lwefilimu, i-molecule ye-hydrogen iqala ukukhanga ngamakhemikhali bese ihlukana ibe ama-athomu e-hydrogen ebusweni befilimu, eyakamuva iyancibilika ku-alloy yakhe ama-hydrides, bese amancane. ama-athomu e-hydrogen atholakala esikhaleni se-alloy lattice futhi angahamba ngokukhululeka. Eqhutshwa i-concentration gradient, ama-athomu e-hydrogen asakazekela kolunye uhlangothi lolwelwesi futhi ahle aphume, aphinde ahlangane abe ama-molecule e-hydrogen kanye nokuncibilika. Ngaphezu kwe-hydrogen nama-isotopes ayo, ayikho enye igesi engadlula kulwelwesi, ngakho ulwelwesi lwezikhali lungasetshenziswa ukuthola i-hydrogen ehlanzekile kakhulu. Izinga le-hydrogen transmembrane lihlobene nezinga lokushisa, ukujiya kwefilimu kanye nomehluko we-hydrogen ingxenye yengcindezi P nhlangothi zombili zefilimu. Ukwenyuka kwezinga lokushisa, ukukhulisa i-P yomuntu kanye nokuncipha kokujiya kwefilimu kungakhuphula ukungena kwe-hydrogen. Nokho, uma izinga lokushisa liphezulu kakhulu, lizokwandisa ukusetshenziswa kwamandla futhi linciphise amandla angokomzimba efilimu. Ngakho-ke, izinga lokushisa ngokuvamile lilawulwa cishe ku-400C. Okunye ukungcola kungaholela ku-membrane ushevu, kunciphise ukungena kwe-ammonia kulwelwesi, futhi kubhubhise nolwelwesi. Ubuthi bomthofu bungabangelwa i-mercury, i-arsenide, i-halide, umhwamuko kawoyela, isibabule ne-ammonia kanye nothuli. Ingxubevange ye-aluminium ingenziwa ibe amashubhu (amashubhu) noma ama-diaphragm (amafilimu).
