I-Metal foam yimathiriyeli yesinyithi enomgongxo eyenziwe yinethiwekhi yentsimbi ekhethekileyo, ngenxa yoko inokuqina okuqinileyo, ukukhaphukhaphu, ukuqina komphezulu ophakamileyo, ingxolo ephantsi, ukugquma ubushushu, kunye nezinye iipropathi ezigqwesileyo. Okwangoku, ukusetyenziswa kwe-foam yensimbi kuya kubanzi kwaye kubanzi, kusetyenziswe ngokubanzi kwiinkalo ezahlukeneyo, kunye namandla abanzi kunye nekamva elithembisayo.

Kwinkulungwane yama-21, ngezixhobo zomkhosi eziya zihambela phambili ngokwandayo, zombini ulwaphulo-mthetho kunye nokhuselo kufuneka luxhomekeke kwiinkqubo zenzululwazi, ezinamandla nezikhaphukhaphu zesikrweqe somzimba (izigcina-ntloko, iihempe zangaphantsi, amagxa, iimaski zobuso) ukuzinqanda ekubeni zijikwe zibe ngumxhesho wenkanunu.
Sesiphi isikrweqe somzimba esikhuselekileyo ngoku ekubeni iteknoloji yasemkhosini ihambele phambili? Impumelelo yamva nje ziihempe zangaphantsi ezingangenwa bullet ezenziwe ngogwebu lwentsimbi oludityanisiweyo olunokuqhawula imbumbulu ebhabhayo ngolonwabo.
Ayisiyo nayiphi na isinyithi, kodwa yenziwe ngokunyibilikisa i-aluminiyam malunga nebhola yentsimbi engenanto. I-foam yesinyithi edibeneyo ingaphezulu kwe-70% elula kunentsimbi yentsimbi eqhelekileyo - kwaye ifunxa amandla angama-80 ngaphezu kwentsimbi. Isikrweqe somzimba senziwe nge-foam yentsimbi edibeneyo kunye ne-boron carbide ceramic, ngelixa ipleyiti yangasemva yiKevlar.

I-nickel foam yimathiriyeli ye-foam evuzayo kakhulu, ephantsi, ene-dimensional-dimensional ye-3-dimensional reticulated, into entsha nekhula ngokukhawuleza kwizinto zangoku zesayensi. Ulwakhiwo lwe-foam lunika isinyithi se-nickel i-open-cell structure, esinika ukugqithisela okugqwesileyo kunye nokugqithiswa kobushushu okubalulekileyo kunye neempawu zokulahla.
I-foam ye-nickel yenziwe nge-electroplating kwi-skeleton yeepolymers ezikhethekileyo kunye nesakhiwo sothungelwano esine-ntathu-dimensional, njenge-polyurethane, i-polyester polyurethane kunye nezinye iipolymers ezikhethekileyo (iziponji). Emva kokufakwa, imveliso yokugqibela ye-foam yesinyithi yenziwa ngokutshisa i-polymer yangaphakathi kunye nokunciphisa i-oxides yesinyithi, kwaye ibunjwe ngoomatshini ngonyango lobushushu beekhemikhali.
I-nickel foam, kunye neempawu zayo ezilula kunye nezixhobo zombane, yenye yezona zinto zibalulekileyo zokwakha i-AEM's hydrogen electrolyzers, ebonelela ngesisombululo esifanelekileyo sokuvelisa i-hydrogen esebenzayo kunye nezinzileyo.
