Nā papa bipolar

Nā papa bipolarhana ʻia me ka graphite a i ʻole ka metala; hoʻolaha like lākou i ka wahie aka mea hoʻoheheʻe oxidant i nā pūnaewele o ke kelepona wahieHōʻiliʻili pū lākou i ke au uila i hana ʻia ma nā kikowaena hoʻopuka.

I loko o kahi keena wahie hoʻokahi-kelepona, ʻaʻohe papa bipolar; eia naʻe, aia kahi papa hoʻokahi ʻaoʻao e hāʻawi anake kahe ʻana o nā electronsI loko o nā cell wahie nona nā cell he nui ma mua o hoʻokahi, aia ma ka liʻiliʻi hoʻokahi papa bipolar (aia ka mana kahe ma nā ʻaoʻao ʻelua o ka papa). Hāʻawi nā papa bipolar i kekahi mau hana i loko o ke cell wahie.

ʻO kekahi o kēia mau hana e pili ana i ka hoʻokaʻawale ʻana o ka wahie a me ka oxidant i loko o nā cell, ka hoʻokaʻawale ʻana o nā cell like ʻole, ka hōʻiliʻili ʻana oke au uilai hana ʻia, ka hoʻokuʻu ʻana o ka wai mai kēlā me kēia cell, ka hoʻohaʻahaʻa ʻana o nā kinoea a me ka hoʻolulu ʻana o nā cell. Loaʻa i nā papa Bipolar nā kahawai e ʻae ai i ka hele ʻana o nā reactants (wahie a me ka oxidant) ma kēlā me kēia ʻaoʻao. Hoʻokumu lākounā ʻāpana anode a me cathodema nā ʻaoʻao ʻē aʻe o ka papa bipolar. Hiki ke ʻokoʻa ka hoʻolālā o nā kahawai kahe; hiki ke linear, coiled, parallel, like me ka comb a i ʻole kaʻawale like e like me ka mea i hōʻike ʻia ma ke kiʻi ma lalo.

ʻO nā ʻano like ʻole o ka papa bipolar [COL 08]. a) Nā kahawai kahe i ʻōwili ʻia; b) nā kahawai kahe coil he nui; c) nā kahawai kahe like; d) nā kahawai kahe interdigitated

Ua koho ʻia nā mea ma muli okūlike kemika, ke kūpaʻa ʻana i ka palaho, kumukūʻai,alakaʻi uila, ka hiki ke hoʻolaha kinoea, ka impermeability, ka maʻalahi o ka mīkini ʻana, ka ikaika mechanical a me kā lākou conductivity thermal.
