Hoʻouna wikiwiki ʻia no Kina Graphite Bipolar Plate no Pem Fuel Cell kiʻi i hōʻike ʻia

ʻO ka wehewehe pōkole:

ʻO ka pā Bipolar ke kākoʻo kumu nui o ka waihona wahie, a ʻo kāna hoʻolālā hoʻolālā e hoʻokumu i ke kahawai kahe o ka hydrogen, ea a me ka wai i loko o ka waihona. E like me ke ʻano nui o ka waihona, ʻo ka mānoanoa o ka pā bipolar e pili pono i ka mana o ka pā. I kēia manawa, ma muli o ka paepae kiʻekiʻe o ka ʻenehana electrode membrane i ka ʻoihana, ua lohi ka holomua holomua, a ʻo ka hoʻomaka ʻana o ka hoʻomaikaʻi ʻana i ka hana o nā huahana stack ka mea nui ma ka pā bipolar.

Pono ka pā bipolar o ka wahie cell e hoʻokō i kēia mau koi hana:

I mea e pāʻani ai i kahi hana i loko o ke kelepona hoʻokahi, pono ke kiʻekiʻe ka conductivity o ka pā bipolar; e hoʻokaʻawale i ke kinoea hopena a me ka wai hoʻoheheʻe wela i kēlā me kēia lua, pono e hoʻokō ke kinoea permeability o ka pā bipolar i nā koi;

Hoʻololi koke ʻia ka wela o ka wahi pane i ka coolant, a ʻo ka pā bipolar e loaʻa i ka conductivity thermal kiʻekiʻe; e noʻonoʻo ana i ka ikaika o ka hale, ka haʻalulu, ka mana a me ka haʻahaʻa haʻahaʻa o ka hoʻomaka ʻana, ʻo ka ikaika, ka nui a me ka hiki ke wela o ka mea pā bipolar e hoʻokō pono i nā koi hana huahana.

E hoʻouna i ka leka uila iā mākou Hoʻoiho ma ke ʻano he PDF

Huahana Huahana

Hoʻopili ʻo ia i ka ʻōlelo "Hoʻopono, hana, ʻoihana, hana hou" e hoʻomohala mau i nā huahana hou. Manaʻo ʻo ia i nā mea kūʻai aku, kūleʻa e like me kona kūleʻa ponoʻī. E hoʻomohala i ka lima maikaʻi i ka wā e hiki mai ana no ka lawe wikiwiki ʻana no Kina Graphite Bipolar Plate no Pem Fuel Cell, Ke nānā nei i ka hiki, kahi ala lōʻihi e hele ai, e hoʻoikaika mau ana e lilo i poʻe limahana āpau me ka hoihoi piha, hoʻokahi haneli ka hilinaʻi a kau. Ua kūkulu kā mākou ʻoihana i kahi kaiapuni nani, nā huahana kiʻekiʻe, kiʻekiʻe kiʻekiʻe o ka papa hana mua a me ka hana paʻakikī!
Hoʻopili ʻo ia i ka ʻōlelo "Hoʻopono, hana, ʻoihana, hana hou" e hoʻomohala mau i nā huahana hou. Manaʻo ʻo ia i nā mea kūʻai aku, kūleʻa e like me kona kūleʻa ponoʻī. E hooulu kakou i ka lima e hiki mai anaPapa Kipi Kina, Kiekie Maemae Graphite, Ua makemake nui mākou e hui pū me nā hui ʻē aʻe e mālama nui ana i ka maikaʻi maoli, ka lako paʻa, ka mana ikaika a me ka lawelawe maikaʻi. Hiki iā mākou ke hāʻawi i ke kumukūʻai hoʻokūkū me ke kiʻekiʻe kiʻekiʻe, no ka mea, ʻoi aku ka MORE Expert. Hoʻokipa ʻia ʻoe e kipa i kā mākou hui i kēlā me kēia manawa.

Hōʻike huahana

Ua hoʻomohala mākou i nā papa graphite bipolar kumu kūʻai no PEMFC e koi ana i ka hoʻohana ʻana i nā papa bipolar kiʻekiʻe me ka conductivity uila kiʻekiʻe a me ka ikaika mechanical maikaʻi. ʻO kā mākou mau papa bipolar e ʻae i nā pūnaewele wahie e hana i nā wela kiʻekiʻe a loaʻa iā ia ka conductivity uila a me ka wela.

Hāʻawi mākou i ka mea graphite me ka resin impregnated i mea e hoʻokō ai i ka impermeability kinoea a me ka ikaika kiʻekiʻe. Akā, mālama ka mea waiwai i nā waiwai maikaʻi o ka graphite ma ke ʻano o ka conductivity uila kiʻekiʻe a me ka conductivity thermal kiʻekiʻe.

Hiki iā mākou ke mīkini i nā papa bipolar ma nā ʻaoʻao ʻelua me nā māla kahe, a i ʻole ka mīkini ʻaoʻao hoʻokahi a i ʻole e hāʻawi pū i nā pā palaka unmachined. Hiki ke hana ʻia nā papa graphite āpau e like me kāu hoʻolālā kikoʻī.

Pepa ʻIkepili Mea Pilikino Graphite Bipolar Plates:

Mea waiwai	ʻAiʻi Nui	ʻoluʻolu Ka ikaika	Ka ikaika hoʻopili	Kū'ē Kūikawā	Wehe Porosity
GRI-1	1.9 g/cc min	45 Mpa min	90 Mpa min	10.0 micro ohm.m max	5% ka nui
Loaʻa nā māka o nā mea graphite e koho e like me ke noi kikoʻī.

Nā hiʻohiʻona:
- Impermeable i nā kinoea (hydrogen a me oxygen)
- Kokoke uila conductivity
- He kaulike ma waena o ka conductivity, ka ikaika, ka nui a me ke kaumaha
- Ke kū'ē i ka corrosion
- Maʻalahi e hana i nā hiʻohiʻona nui:
