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 | Open 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:
- Kūʻai-pono
