Umbono womzobi wento endala kaMars ekusenokwenzeka ukuba yayijongeka ngayo, ngokusekwe kwidatha yejoloji.Wikimedia Izazinzulu zisandula ukungqina ukuba bekukho (kwaye kusekho) amanzi amaninzi kwiMars. Ukufumanisa kukhulu hayi kuphela kuba phi kukho amanzi kukho ubomi , kodwa nangenxa yokuba kuthetha ukuba abantu banokuxhomekeka kula manzi ngenkxaso yobomi kunye nemithombo yamafutha kwimishini yeplanethi yexesha elizayo, endaweni yokuhambisa yonke into eMhlabeni.
Kude kube ngoku, bekukho ingxaki enkulu enye: Phantse onke amanzi kwiPlanethi ebomvu namhlanje akho ngohlobo lwe-brine ice, eshiye ngasemva ngamachibi kunye neelwandle zamanzi amandulo. Ukuyiguqula ibe zi-fuel ezisetyenziswayo yinkqubo entsonkothileyo nexabisa kakhulu. Okokuqala, amanzi kwityuwa kufuneka ahlukaniswe emanzini-ngesiqhelo ngokufudumeza-kwaye ke amanzi acociweyo kufuneka afakwe umbane afumane ioksijini kunye nehydrogen.
Into entsha eyenziwe liqela leenjineli kwiYunivesithi yaseWashington malunga nokutshintsha loo nto ngonaphakade.

Kwi ukufunda epapashwe kwiphephancwadi Iinkqubo ze-National Academy of Sciences (PNAS) NgoMvulo, abaphandi baseYunivesithi yaseWashington i-McKelvey School of Engineering babeke uyilo lwe-electrolyser ekhethekileyo enokukhupha i-hydrogen kunye neoksijini ngokuthe ngqo kumanzi etyuwa. Inkqubo ibonakalisiwe ukuba isebenza ngokugqibeleleyo kwisimo seMartian esilinganayo kwi -36 ° C.
Indlela yethu ibonelela ngendlela eyahlukileyo eya kwinkxaso-yobomi kunye nemveliso yamafutha kwimishini yoluntu yexesha elizayo kwiMars, ababhali bophando babhala kwi-abstract.
I-electrolyzer yemveli ine-anode kunye ne-cathode eyahlulwe ngenwebu ye-electrolyte. Kwi-anode, amanzi ayasabela ukwenza ioksijini kunye ne-hydrogen ion ion ngokuqinisekileyo. Khetha ion hydrogen emva koko udlule kwi-membrane ye-electrolyte ukuya kwi-cathode kwaye wenze igesi ye-hydrogen ngokudibanisa nee-elektroni ezivela kwisekethe yangaphandle.
Ukutshintsha le nkqubo kwimeko yetyuwa, iYunivesithi yaseWashington ilebhu isebenzisa izinto zenoveli ze-anode kunye ne-cathode. I-brine electrolyser yethu ibandakanya i-anode ekhokelayo ye-ruthenate pyrochlore anode ephuhliswe liqela lethu ngokudibeneyo neplatinum kwi-carbon cathode, ucacisa uVijay Ramani, umbhali ophambili wesifundo. Ezi zinto ziyilwe ngononophelo, kunye nokusetyenziswa ngokupheleleyo kwemigaqo yobunjineli yemveli, ivelise oku kusebenza okuphezulu.
Ngokophando, le electrolyser inokuvelisa i-oksijini ephindaphindwe ngama-25 kune-MOXIE yeoksijini yomvelisi kwi-NASA's Perseverance rover. I-MOXIE imfutshane kwi-Oxygen ye-Mars ye-In-Situ Resource Utility Testing.
I-electronyser yethu yaseMartian brine iyitshintsha kakhulu i-calculator ye-calculus ye-mission ukuya kwi-Mars nangaphezulu, uRamani wongeze.
Phambi kokuba umhlaba uhlale kwiMars, le nkqubo inokusetyenziselwa ukufakela amanzi olwandle eMhlabeni kuphononongo olunzulu lwaselwandle, njengokudala ioksijini kwimfuno yeenkwili.
