- Graphite bipolar plaque nibintu byingenzi bigize ibice bigize selile ya hydrogène selile, bingana na 60% byubunini bwa stack, hejuru ya 80% byuburemere, na 30-40% yikiguzi. Ntabwo ari isahani yo kugabana ya selire ya batiri gusa, ahubwo ni plaque yumurima hamwe nicyapa cyegeranya, ishinzwe imirimo myinshi nko gukwirakwiza imyuka ya reaction, gukusanya amashanyarazi, ubushyuhe n’amazi, hamwe nubufasha bwa mashini.
- Kuki ukoresha grafite aho gukoresha ibyuma? Ibidukikije bikora bya selile birihariye - hariho aside electrolytike (proton yo guhanahana ibintu), ubuhehere bwinshi, hamwe nikirere cya redox imbere. Ibyuma bipolar byuma bikunda kwangirika muri ibi bidukikije, kandi ibicuruzwa byangirika birashobora kwanduza catalizator, bigatuma imikorere ya batiri igabanuka. Graphite bipolar plaque ifite ubudahangarwa bukomeye bwa chimique, birwanya kure cyane kwangirika kwibyuma, gutwara neza, hamwe nubucucike buke, bigatuma bahitamo inzira nyamukuru ya selile yubucuruzi muri iki gihe.
- Isahani ya bipolar isahani igabanijwemo ibyiciro bitatu ukurikije uburyo bwo gukora:
Plates Isahani ya bipite yuzuye ya bipolar - ikozwe hejuru - grafite isukuye ikoresheje inzira yo gusya neza, hamwe nibikorwa byiza ariko bihenze kandi byigihe kirekire byo gutunganya;
Plate Kwagura plaque bipolar plaque - byakozwe mugushiraho kashe ya grafite yoroheje, hamwe nigiciro gito ariko imbaraga zubukanishi;
③ Gukomatanya isahani ya bipolar - ifu ya grafite + resin ivanze ibumba, kuringaniza ibiciro nibikorwa, kuri ubu niyo nzira nyamukuru.
- Hamwe n’inganda zitanga ingufu za hydrogène, isoko rya grafite bipolar plate riteganijwe kwiyongera kuva kuri miliyari 5 mu 2025 rikagera kuri miliyari zisaga 30 mu 2030, hamwe n’ubwiyongere bw’umwaka buri hejuru ya 40%. Iyi ni inzira ndende yo gukura hamwe nukuri.
