I-Australia ithuthukisa uhlelo lwebhethri lokugeleza ngamandla amakhulu wamandla kunamabhethri e-lithium
Sekuvele kunezimoto eziningi zebhethri ezisebenzisa i-hydrogen fuel fuel emakethe, kodwa abacwaningi abavela eRoyal Melbourne Institute of Technology e-Australia babeke umqondo wokuthi “ibhethri eligeleza ibhethri”. Uma ubuchwepheshe bungathandwa, bungakhulisa ukumbozwa kwamasistimu wamandla asuselwa ku-hydrogen futhi buwenze ongena esikhundleni samabhethri e-lithium-ion. buyisa i-hydrogen, idivaysi yokugeleza kweproton isebenza kakhulu njengebhethri ngomqondo wendabuko.

Hlanganisa uProfesa JohnAndrews kanye “neproton flow battery system” yakhe yobufakazi bokuqala bomqondo

Uhlelo lwendabuko lubeka amanzi kugesi futhi luhlukanise i-hydrogen ne-oxygen, bese kubagcina kuzo zombili iziphetho zebhethri le-lithium esebenzisa amandla kaphethiloli. Lapho ugesi usuzovela, kuthunyelwa i-hydrogen ne-oxygen ku-electrolyzer ukuze kusetshenziswe amakhemikhali.

Kodwa-ke, ukusebenza kwebhethri lokugeleza kwe-proton kuhlukile-ngoba kuhlanganisa i-electrode yensimbi yokugcina i-electrode kubhethri eguquguqukayo ye-proton exchange membrane (PEM) esebenzisa amandla kagesi.

Usayizi wale divayisi eyisibonelo ngu-65x65x9 mm

Ngokusho kukaJohn Andrews, umcwaningi oholayo wephrojekthi kanye noprofesa ohambisana noMnyango Wezobunjiniyela Nezokukhiqiza eRoyal Melbourne Institute of Technology (RMIT) School of Aerospace Engineering, ibhethri elinama-electrode wesitoreji ahlanganisiwe. Siqede ngokuphelele i-proton yaba igesi. Yonke le nqubo, bese i-hydrogen iye ngqo kwisitoreji esiqinile. ”

Uhlelo lokuguqula lugcina amandla kagesi ku-hydrogen bese “luvuselela” ugesi

Inqubo yokushaja ayibandakanyi inqubo yokubola kwamanzi abe yi-hydrogen ne-oxygen nokugcina i-hydrogen. Kulolu hlelo lomqondo, ibhethri lihlukanisa amanzi ukukhiqiza ama-proton (i-hydrogen ions), bese lihlanganisa ama-electron nezinhlayiya zensimbi kwi-electrode yebhethri ye-lithium enikwe amandla kaphethiloli.

Idizayini yesistimu yokugcina amandla ebhetri

Ekugcineni, amandla agcinwa ngendlela yama-hydride wensimbi aqinile. Enqubeni ebuyela emuva, ingakhiqiza ugesi (namanzi) iphinde ihlanganise ama-proton ne-oxygen esemoyeni (ukukhiqiza amanzi).

“Ibhethri ye-lithium battery esebenzisa amandla aphindayo” ihlanganiswe nama-electrode wokugcina ama-proton (i-X imele ama-athomu wensimbi aqinile aboshelwe ku-hydrogen)

UProfesa Andrew uthe, “Ngoba kugeleza kuphela amanzi kumodi yokushaja — kuphela ukuhamba komoya kumodi ekhiphayo — sibiza uhlelo olusha ibhethri lokugeleza kwe-proton. Uma kuqhathaniswa ne-lithium-ion, amabhethri ama-proton ayonga kakhulu — Ngoba i-lithium idinga ukwembiwa emithonjeni enjengamaminerali ayindlala, amanzi anosawoti noma ubumba. ”

Isitoreji samandla webhethri egelezayo

Abaphenyi bathi, ngokomthetho, ukusebenza kahle kwamandla kwamabhethri okugeleza kwe-proton kungafaniswa namabhethri e-lithium-ion, kepha ukuminyana kwamandla kukhulu kakhulu. USolwazi Andrew uthe, “Imiphumela yokuqala yokuhlola iyajabulisa, kodwa kusenomsebenzi omningi wocwaningo nentuthuko okufanele wenziwe ngaphambi kokuthi usetshenziselwe ukuhweba.”

Leli thimba selakhe uhlobo lokuqala lomqondo wobufakazi obunomqondo osayizi we-65x65x9 mm kuphela (2.5 × 2.5 × 0.3 inches) futhi walushicilela kumagazini i- “International Hydrogen Energy”.
