Ukusetyenziswa kweeMveliso
Ngokuqhelekileyo i-alloy ingenziwa kwi-diaphragm (ebizwa ngokuba yifilimu) kunye ne-membrane ityhubhu (ebizwa ngokuba yi-tube). Ubukhulu befilimu budla ngokuba yi-50 ukuya kwi-100 microns. Isetyenziselwa ikakhulu ukucocwa kweoksijini, kwaye umgaqo wayo yimowudi yokusasazwa kwesisombululo, kwaye amandla okuqhuba ukusasazwa ngumahluko wenxalenye yoxinzelelo lwehydrogen kumacala omabini enwebu. Kwi-300-500C, xa i-hydrogen imathiriyeli ekrwada icinezelwa kwelinye icala lefilimu, i-molecule ye-hydrogen kuqala i-adsorbs ngokwemichiza kwaye iyahlukana ibe yi-athomu ye-hydrogen kumphezulu wefilimu, le yokugqibela inyibilika kwi-alloy ukwenza iihydrides, kunye nencinci. iiathom ze-hydrogen zibekwe kwisithuba se-alloy lattice kwaye zinokuhamba ngokukhululekileyo. Iqhutywa yi-concentration gradient, ii-athomu ze-hydrogen zisasazeka kwelinye icala le-membrane kwaye zikhuphe ngaphandle, ziphinda zidibanise kwiimolekyuli ze-hydrogen kunye ne-desorption. Ukongeza kwi-hydrogen kunye ne-isotopes yayo, akukho rhasi enye inokudlula kwi-membrane, ngoko ke i-membrane exhobileyo ingasetyenziselwa ukufumana i-hydrogen ecocekileyo ye-ultra-high. Umlinganiselo we-hydrogen transmembrane unxulumene nobushushu, ubukhulu befilimu kunye ne-hydrogen inxalenye yoxinzelelo lwe-P kumacala omabini efilimu. Ukonyuka kwamaqondo obushushu, ukwandisa i-P yomntu kunye nokuncipha kobunzima befilimu kunokonyusa ukufikeleleka kwehydrogen. Nangona kunjalo, ukuba iqondo lokushisa liphezulu kakhulu, liya kwandisa ukusetyenziswa kwamandla kunye nokunciphisa amandla omzimba wefilimu. Ngoko ke, iqondo lobushushu lidla ngokulawulwa malunga nama-400C. Okunye ukungcola kunokukhokelela kwityhefu ye-membrane, ukunciphisa i-ammonia yokungena kwi-membrane, kunye nokutshabalalisa inwebu. Ityhefu yelothe inokubangelwa yimercury, arsenide, halide, oil vapor, sulfur and ammonia substances nothuli. I-alloy ye-aluminiyam ingenziwa ibe yimibhobho (iityhubhu) okanye i-diaphragms (iifilimu).
