GDE ipfupiso ye electrode yekupararira kwegasi, zvinoreva electrode yekupararira kwegasi. Mukugadzirwa kwayo, catalyst inoputirwa pachikamu chekupararira kwegasi semuviri unotsigira, uye GDE inodzvanywa nekupisa kumativi ese e membrane yeproton nenzira yekudzvanywa nekupisa kuti igadzire electrode ye membrane.
Nzira iyi iri nyore uye yakakura, asi ine zvinhu zviviri zvakaipa. Chekutanga, catalytic layer yakagadzirwa yakakora, ichida Pt load yakakwira, uye catalyst use rate yakaderera. Chechipiri, kubatana pakati pecatalytic layer neproton membrane hakusi pedyo zvakanyanya, zvichikonzera kuwedzera kweinterface resistance, uye kushanda kwese kwe membrane electrode hakuna kukwira. Saka, GDE membrane electrode yakabviswa zvakanyanya.
Musimboti wekushanda:
Chinonzi gas distribution layer chiri pakati pe electrode. Nekumanikidzwa kushoma, ma electrolyte anobviswa kubva musystem iyi ine maburi. Kuramba kudiki kunoita kuti gasi rifambe zvakasununguka mukati me electrode. Pakumanikidzwa kwemhepo kwakakwira zvishoma, ma electrolyte ari musystem ye pore anovharirwa kune working layer. Rutivi rwepamusoro pacharwo rune maburi madiki zvekuti gasi harigone kuyerera nepakati pema electrode kuenda mu electrolyte, kunyangwe pakumanikidzwa kwakanyanya. Electrode iyi inogadzirwa nekupararira uye sintering inotevera kana kudzvanya kupisa. Kuti igadzire ma electrode ane layer yakawanda, zvinhu zvakacheneswa zvinoparadzirwa mu mold uye zvinogadziriswa. Zvadaro, zvimwe zvinhu zvinoiswa muzvikamu zvakasiyana uye kumanikidzwa kunoiswa.
