Okunnyonnyola

Weereza okwebuuza .

Composite graphite bipolar plate kika kya bipolar plate ekipya, nga kino kisinga kukozesebwa mu butoffaali bw’amafuta ng’ekitundu ekikulu. Eyawula n’okusaasaanya oxidant n’amafuta, etambuza current, ewagira membrane electrode, era etereeza ebbugumu ery’omunda erya reactor.

Ensengeka n’obutonde obusookerwako

1. Ebikozesebwa mu matrix:(1) Graphite phase: graphite ey’obutonde, graphite egaziyiziddwa oba graphite ey’obutonde biwa obutambuzi bw’amasannyalaze obw’amaanyi n’okutebenkera kw’eddagala.

Polymer resins: nga phenolic resin, epoxy resin, okutumbula amaanyi g’ebyuma n’okujjuza ekituli.

Conductive filler: carbon black, carbon fiber oba obutundutundu bw’ekyuma okwongera okutumbula obutambuzi.

2. Enkola ya composite: okuyita mu kubumba, okubumba mu mpiso oba okubumba mu kunyigiriza okw’ebbugumu, graphite etabulwa ne resin/filler n’oluvannyuma n’ewona.

Enkola

Composite graphite bipolar plates ziwa ebirungi nga ssente entono, okuziyiza okukulukuta okulungi ennyo, n’okukola obulungi. Bw’ogeraageranya n’ebyuma ebiyitibwa bipolar plates, byewala bulungi ensonga z’okukulukuta eza bulijjo ezisangibwa mu mbeera z’amafuta. Bwe tugeraageranya ku graphite bipolar plates, ziraga okunyweza kwa ggaasi-okusingako n’amaanyi g’okubeebalama. Ate era, ebintu bino ebigatta bisobola okulongoosebwa okuyita mu nnongoosereza entuufu mu butonde bwa resin, emigerageranyo gy’okujjuza okutambuza, n’okukozesa enkola z’okukyusa graphite oba ebirungo ebigatta resin, okusobozesa okulongoosa omulimu omulungi-tuned.

Ebirungi ebikulu

Omugaso gw’omuwendo: omuwendo gw’ebintu guli wansi ebitundu 30%-50% okusinga pulati ya graphite ennongoofu, era esaanira okubumba n’empiso n’enkola endala ez’okufulumya mu kibinja.
Design flexibility: esobola okukolebwa mu ultra-thin flow channel okulongoosa volume power density ya fuel cell stack.
Durability: Life>essaawa 5000 wansi w’embeera y’amafuta, density ya kasasiro y’okukulukuta<1 μA/cm².

Essuubi ly’okusaba

Olw’okukulaakulana okutambula mu tekinologiya w’amasoboza ga haidrojeni n’okukozesa ennyo obutoffaali bw’amafuta obw’oluwuzi oluwanyisiganya pulotoni, obwetaavu bw’akatale obw’ebipande ebibiri ebiyitibwa composite graphite bipolar plates-ekitundu ekikulu mu nkola z’amafuta g’amafuta-busuubirwa okukula buli lukya. Mu kiseera kino, ng’enkola z’okukola zigenda mulongoosebwa era nga n’ebijjuza ebiyiiya ebitambuza amazzi bikolebwa, ebintu bino ebikoleddwa mu ngeri ey’enjawulo bijja kulaba omulimu ogwongezeddwa, nga biwa obuwagizi obw’amaanyi eri okutunda ebikozesebwa mu by’amafuta.
