Pāpā Kilaki Bipolar, graphite bipolar pā no ka hydrogen wahie cell,
Pāpā Kilaki Bipolar, ʻO ka pāpaʻi kiʻi Bipolar no ka pahu wahie, kalapona Bipolar plate, ʻO ka pā kalapona bipolar no ka pahu wahie,
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)
– Ka hoʻoili uila kūpono
- 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:
– He kumu kūʻai
