He mea tino nui te hangarau whakaputa hauwai matomato mō te whakatutukitanga o te ōhanga hauwai, nā te mea, he rerekē ki te hauwai hina, kāore te hauwai matomato e whakaputa i te nui o te hauhā waro i te wā e hangaia ana. Kei te arohia ngā pūtau hiko waikura totoka (SOEC), e whakamahi ana i te pūngao whakahou hei tango hauwai mai i te wai, nā te mea kāore e whakaputa i ngā poke. I roto i ēnei hangarau, he pai ngā painga o ngā pūtau hiko waikura totoka pāmahana teitei, arā, he tino whai hua me te tere whakaputa.
Ko te pākahiko uku proton he hangarau SOEC pāmahana-teitei e whakamahi ana i te electrolyte uku proton hei whakawhiti i ngā katote hauwai ki roto i tētahi rauemi. Ka whakamahia hoki e ēnei pākahiko he hangarau e whakaiti ana i ngā pāmahana whakahaere mai i te 700°C neke atu rānei ki te 500°C iti iho rānei, ā, ka whakaitihia te rahi me te utu o te pūnaha, ka whakapai ake hoki i te pono mō te wā roa mā te whakaroa i te koroheketanga. Heoi, i te mea kāore anō kia mārama te tikanga matua e kawenga ana mō te sintering i ngā electrolyte uku protic i ngā pāmahana iti i te wā o te tukanga hanga pākahiko, he uaua ki te neke ki te wāhanga hokohoko.
I kī te tīma rangahau i te Energy Materials Research Center i te Korea Institute of Science and Technology kua kitea e rātou tēnei tikanga whakamahana irahiko, e whakaara ake ana i te āheinga o te hokohoko: he whakatupuranga hou tēnei o ngā pākahiko uku tino whai hua kāore anō kia kitea i mua.
I hoahoa, i whakahaerehia hoki e te tīma rangahau ngā tauira whakamātautau maha i runga i te pānga o te wāhanga whakawhiti ki te whakakīkī irahiko i te wā e whakakīkī ana irahiko. I kitea mō te wā tuatahi mā te whakarato i tētahi iti o ngā rauemi āwhina whakakīkī hau mai i te irahiko whakawhiti ka taea te whakatairanga i te whakakīkī o te irahiko. He onge ngā āwhina whakakīkī hau, ā, he uaua ki te tirotiro hangarau. Nō reira, kāore anō kia whakaarohia te whakapae ko te whakakīkī irahiko i roto i ngā pūtau uku proton nā te kaihoko whakakīkī mimiti. I whakamahia e te tīma rangahau te pūtaiao rorohiko hei manatoko i te kaihoko whakakīkī hau, ā, i whakaū kāore te tauhohenga e whakararu i ngā āhuatanga hiko ahurei o te irahiko. Nō reira, ka taea te hoahoa i te tukanga hanga matua o te pākahiko uku proton.
"Mā tēnei rangahau, kua tata atu mātou ki te whakawhanake i te tukanga hanga matua mō ngā pākahiko uku proton," te kī a ngā kairangahau. Kei te whakamahere mātou ki te ako i te tukanga hanga o ngā pākahiko uku proton whai hua nui ā muri ake nei."
