Pereti Karāwhite Wāhanga Pūtau Wahie, Pereti Waro-rua

He rauemi pereti rua-ira te rauemi karāpiti i whakawhanakehia, i whakamahia hoki i mua. Ko ngā pereti rua-ira tuku iho e whakamahi ana i ngā pereti karāpiti kore-porous, ā, ka tukatukahia ngā awaawa mā te mīhini. He iti te tauwehenga whānui wera o te pereti rua-ira karāpiti, he pai te kawe wera, he pumau ngā āhuatanga matū, he pai te ātete ki te waikura me te kaha kawe hiko. Heoi, nā te pakarukaru o te karāpiti ka uaua te tukatuka, ā, i te wā kotahi ka whakawhāiti i te whakaiti i te matotoru o te pereti karāpiti, ā, he ngāwari te whakaputa i ngā pore i te wā o te tukanga hanga, kia taea ai e te wahie me te waikura te uru tetahi ki tetahi, nō reira me tāpiri atu ētahi atu matū hei whakapai ake i te mahi a te pākahiko.

Kua whakawhanakehia e mātou he pereti bipolar karāhe utu-pai mō te PEMFC, e hiahia ana kia whakamahia he pereti bipolar matatau me te kawe hiko teitei me te kaha miihini pai. Mā ā mātou pereti bipolar ka taea e ngā pūtau wahie te mahi i ngā pāmahana teitei, ā, he pai hoki te kawe hiko me te wera.

Ka tukuna atu e mātou te rauemi karāpeti kua whakakiia ki te kapia kia kore ai e uru te hau me te kaha nui. Heoi, ka mau tonu ngā āhuatanga pai o te karāpeti i roto i te kawe hiko me te kawe wera nui.

Ka taea e mātou te mīhini i ngā pereti bipolar i ngā taha e rua me ngā mara rere, te mīhini rānei i te taha kotahi, te whakarato rānei i ngā pereti pātea kāore anō kia mīhinihia. Ka taea te mīhini i ngā pereti graphite katoa kia rite ki tāu hoahoa taipitopito.
