I-GDE yisifinyezo se-electrode yokusabalala kwegesi, okusho i-electrode yokusabalala kwegesi. Enqubweni yokukhiqiza, i-catalyst imbozwa ungqimba lokusabalala kwegesi njengomzimba osekelayo, bese i-GDE icindezelwa ngokushisa kuzo zombili izinhlangothi ze-membrane ye-proton ngendlela yokucindezela ngokushisa ukuze kwakheke i-electrode ye-membrane.
Le ndlela ilula futhi ivuthiwe, kodwa inezinkinga ezimbili. Okokuqala, ungqimba lwe-catalytic olulungisiwe lujiyile, ludinga umthwalo we-Pt ophezulu, kanti izinga lokusetshenziswa kwe-catalyst liphansi. Okwesibili, ukuxhumana phakathi kwengqimba ye-catalytic kanye ne-proton membrane akusondelene kakhulu, okuholela ekuqineni kokumelana kwe-interface, futhi ukusebenza okuphelele kwe-membrane electrode akuphezulu. Ngakho-ke, i-GDE membrane electrode isusiwe ngokuyisisekelo.
Isimiso sokusebenza:
Ingqimba ebizwa ngokuthi igesi itholakala phakathi kwe-electrode. Ngokucindezela okuncane kakhulu, ama-electrolyte ayasuswa kulesi simiso esinezimbobo. Ukumelana nokugeleza okuncane kuqinisekisa ukuthi igesi ingageleza ngokukhululeka ngaphakathi kwe-electrode. Ngokucindezela komoya okuphezulu kancane, ama-electrolyte ohlelweni lwezimbobo agcinwa kungqimba olusebenzayo. Ingqimba engaphezulu ngokwayo inezimbobo ezincane kangangokuthi igesi ayikwazi ukugeleza ngama-electrode iye ku-electrolyte, ngisho noma ingcindezi iphezulu. Le electrode yenziwa ngokuhlakazeka kanye nokusila okulandelayo noma ukucindezela okushisayo. Ukuze kukhiqizwe ama-electrode anezingqimba eziningi, izinto ezincane ezisatshalaliswa ku-mold bese zibushelelezi. Bese, ezinye izinto zisetshenziswa ezingqimbeni eziningi bese kusetshenziswa ingcindezi.
