He pā bipolar, he mea nui o ka wahie

Nā papa bipolar

Nā papa bipolarhana ʻia me ka graphite a i ʻole metala; puunaue like lakou i ka wahie aka oxidant i nā pūnaewele o ka wahie. ʻOhi pū lākou i ke au uila i hana ʻia ma nā hopena puka.

I loko o ka pahu wahie hoʻokahi-cell, ʻaʻohe pā bipolar; akā naʻe, aia kahi papa ʻaoʻao hoʻokahi e hāʻawike kahe ana o na electrons. I loko o nā pūnana wahie i ʻoi aku ma mua o hoʻokahi keena, aia ma ka liʻiliʻi hoʻokahi pā bipolar (aia ka mana kahe ma nā ʻaoʻao ʻelua o ka pā). Hāʻawi nā papa bipolar i nā hana he nui i loko o ka cell fuel.

ʻO kekahi o kēia mau hana, ʻo ia ka hāʻawi ʻana i ka wahie a me ka oxidant i loko o nā cell, ka hoʻokaʻawale ʻana o nā ʻāpana like ʻole, ka hōʻiliʻili oke au uilahana ʻia, ka hoʻokuʻu ʻana o ka wai mai kēlā me kēia cell, ka humidification o nā kinoea a me ka hoʻomaha ʻana o nā cell. Loaʻa i nā papa bipolar nā ala e hiki ai ke hele i nā mea hoʻoheheʻe (ka wahie a me ka oxidant) ma kēlā me kēia ʻaoʻao. Hoʻokumu lākounā ʻāpana anode a me ka cathodema nā ʻaoʻao kūʻē o ka pā bipolar. ʻOkoʻa paha ka hoʻolālā ʻana o nā kahawai kahe; he laina laina, ʻōwili, ʻālike, like me ka huila a i ʻole like ʻole e like me ka mea i hōʻike ʻia ma ke kiʻi ma lalo.

ʻO nā ʻano like ʻole o ka pā bipolar [COL 08]. a) nā kahawai kahe i wili ʻia; b) nā kaha kahe o ka coil; c) nā kahawai kahe like; d) nā kahawai kahe interdigitated

Koho ʻia nā mea ma muli oka launa pū kemika, pale ʻino, koina,uila uila, hiki ke hoʻoheheʻe kinoea, impermeability, maʻalahi o ka mīkini, ka ikaika mechanical a me kā lākou conductivity thermal.
