ʻO kā mākou mau limahana i ka ʻuhane o ka "hoʻomaikaʻi mau a me ka maikaʻi", a me nā huahana ʻoi aku ka maikaʻi, ke kumu kūʻai maikaʻi a me nā lawelawe ma hope o ke kūʻai aku, ke hoʻāʻo nei mākou e lanakila i ka hilinaʻi o kēlā me kēia mea kūʻai aku no Renewable Design for Graphite Bipolar Plate no Pem Fuel Cell.
ʻO kā mākou mau limahana i ka ʻuhane o ka "hoʻomaikaʻi mau a me ka maikaʻi", a me nā huahana maikaʻi loa, kumukūʻai maikaʻi a me nā lawelawe ma hope o ke kūʻai ʻana, hoʻāʻo mākou e lanakila i ka hilinaʻi o kēlā me kēia mea kūʻai aku.ʻO ka pāpaʻi kiʻi kiʻi Kina a me ka graphite maʻemaʻe kiʻekiʻe, I kēlā me kēia makahiki, nui nā mea kūʻai aku e kipa i kā mākou hui a loaʻa i nā holomua ʻoihana nui e hana pū me mākou. Hoʻokipa maikaʻi mākou iā ʻoe e kipa mai iā mākou i kēlā me kēia manawa a hui pū mākou e lanakila i kahi kūleʻa nui aʻe i ka ʻoihana lauoho.
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 Maʻamau o nā Papa Bipolar Graphite:
| 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
