GDE ni iki?

GDE ni incamake ya electrode ikwirakwiza umwuka, bivuze electrode ikwirakwiza umwuka. Mu gihe cyo gukora, catalyst ishyirwa ku gice cyo gukwirakwiza umwuka nk'umubiri ushyigikira, hanyuma GDE igakandagira ku mpande zombi za membrane ya proton mu buryo bwo gukandagira gushyushye kugira ngo habeho electrode ihuza umwuka.

Ubu buryo bworoshye kandi bukuze, ariko bufite ingaruka mbi ebyiri. Ubwa mbere, urwego rwa catalytic rwateguwe rurakomeye, rusaba umutwaro mwinshi wa Pt, kandi igipimo cyo gukoresha catalytic ni gito. Icya kabiri, aho urwego rwa catalytic ruhurira n'urugingo rwa proton rutari hafi cyane, bigatuma habaho kwiyongera kwa resistance, kandi imikorere rusange ya electrode ya membrane ntabwo iri hejuru. Kubwibyo, electrode ya GDE membrane yakuweho muri rusange.

Ihame ry'imikorere:

Icyitwa urwego rwo gukwirakwiza gazi kiri hagati muri electrode. Iyo umuvuduko muke cyane, electrolyte zikurwa muri iyi sisitemu ifite imyenge. Ubudahangarwa buke bw'amazi butuma gazi ishobora gutembera neza muri electrode. Iyo umuvuduko w'umwuka uri hejuru gato, electrolyte ziri muri sisitemu y'imyenge zishyirwa ku rwego rw'imikorere. Urusobe rw'amazi ubwarwo rufite imyobo mito ku buryo gazi idashobora gutembera muri electrode ijya muri electrolyte, ndetse no mu gihe cy'umuvuduko mwinshi. Iyi electrode ikorwa hakoreshejwe gukwirakwira no gushyuha nyuma. Kugira ngo hakorwe electrode zifite imyenge myinshi, ibikoresho bifite imyenge mito bikwirakwizwa mu ibumba hanyuma bigatunganywa neza. Hanyuma, ibindi bikoresho bishyirwa mu byiciro byinshi hanyuma umuvuduko ugashyirwamo.
