GDE ke khutsufatso ea electrode ea phallo ea khase, e bolelang electrode ea phallo ea khase. Ha ho etsoa tlhahiso, "catalyst" e koahetsoe holim'a lera la phallo ea khase e le 'mele o tšehetsang, ebe GDE e hatelloa ka mahlakoreng ka bobeli a lera la proton ka tsela ea ho hatella ho chesang ho etsa lesela la electrode.
Mokhoa ona o bonolo ebile o hōlile, empa o na le mefokolo e 'meli. Ntlha ea pele, sekhahla se lokiselitsoeng sa catalytic se teteaneng, se hlokang mojaro o phahameng oa Pt, 'me sekhahla sa tšebeliso ea lisebelisoa se tlaase. Ea bobeli, ho kopana pakeng tsa lera la catalytic le lera la proton ha le haufi haholo, ho fella ka ho eketseha ha khanyetso ea li-interface, 'me ts'ebetso ea kakaretso ea membrane electrode ha e phahame. Ka hona, elektrode ea membrane ea GDE e felisitsoe.
Molao-motheo oa ts'ebetso:
Seo ho thoeng ke kabo ea khase lera e teng bohareng ba eleketrode. Ka khatello e fokolang haholo, li-electrolyte li tlosoa tsamaisong ena ea porous. Phallo e nyane. ho hanyetsa ho tiisa hore khase e ka phalla ka bolokolohi ka har'a electrode. Ha khatello ea moea e phahame hanyane, li-electrolyte tse tsamaisong ea pore li koalehile lera le sebetsang. Sebaka se ka holimo ka boeona se na le masoba a matle hoo khase e ke keng ea phalla ka li-electrode ho ea ho electrolyte, esita le khatello ea tlhōrō. Electrode ena e entsoe ka ho hasana le sintering e latelang kapa ho tobetsa ho chesang. Ho hlahisa li-electrode tsa multilayer, lisebelisoa tse ntle li qhalakanngoa ka hlobo 'me li boreleli. Joale, lisebelisoa tse ling li sebelisoa ka mekhahlelo e mengata 'me ho sebelisoa khatello.
