Pono pono ka ʻenehana hana hydrogen ʻōmaʻomaʻo no ka hoʻokō ʻana i ka hoʻokele waiwai hydrogen no ka mea, ʻaʻole like me ka hydrogen hina, ʻaʻole hoʻopuka ka hydrogen ʻōmaʻomaʻo i ka nui o ka carbon dioxide i ka wā o kāna hana ʻana. ʻO nā cell electrolytic solid oxide (SOEC), ka mea e hoʻohana i ka ikehu hou e unuhi i ka hydrogen mai ka wai, ke huki nei i ka nānā ʻana no ka mea ʻaʻole lākou e hana i nā mea haumia. Ma waena o kēia mau ʻenehana, ʻoi aku ka maikaʻi o ke kiʻekiʻe kiʻekiʻe solid oxide electrolytic cell i nā pono o ka hana kiʻekiʻe a me ka wikiwiki wikiwiki.
ʻO ka pākaukau proton ceramic kahi ʻenehana SOEC wela kiʻekiʻe e hoʻohana ana i kahi proton ceramic electrolyte e hoʻololi i nā ion hydrogen i loko o kahi mea. Hoʻohana pū kēia mau ʻenehana i kahi ʻenehana e hoʻemi ana i nā mahana hana mai 700 ° C a i ʻole ke kiʻekiʻe a hiki i 500 ° C a i ʻole ka haʻahaʻa, e hōʻemi ana i ka nui o ka ʻōnaehana a me ke kumukūʻai, a hoʻomaikaʻi i ka hilinaʻi lōʻihi ma ka hoʻopaneʻe ʻana i ka ʻelemakule. Eia nō naʻe, ʻoiai ʻaʻole i wehewehe maopopo ʻia ke ʻano kumu nui no ka sintering protic ceramic electrolytes i nā haʻahaʻa haʻahaʻa i ka wā o ke kaʻina hana pākaukau, paʻakikī ke neʻe i ke kahua kūʻai.
ʻO ka hui noiʻi ma ka Energy Materials Research Center ma ka Korea Institute of Science and Technology ua hoʻolaha lākou ua ʻike lākou i kēia ʻano hana sintering electrolyte, e hoʻonui ana i ka hiki ke kūʻai aku: he hanauna hou ia o nā pihi seramika kiʻekiʻe i ʻike ʻole ʻia ma mua. .
Ua hoʻolālā a hoʻokō ka hui noiʻi i nā hoʻokolohua like ʻole e pili ana i ka hopena o ke kaʻina transient ma ka hoʻopaʻa ʻana i ka electrolyte i ka wā o ka sintering electrode. Ua ʻike lākou no ka manawa mua e hiki ai i ka hāʻawi ʻana i kahi mea liʻiliʻi o ke kinoea sintering mea kōkua mai ka electrolyte transient hiki ke hoʻoikaika i ka sintering o ka electrolyte. He kakaikahi a paʻakikī ka nānā ʻana i nā mea kōkua kinoea. No laila, ʻaʻole i manaʻo ʻia ke kuhiakau e pili ana i ka densification electrolyte i nā cell ceramic proton e ka vaporizing sintering agent. Ua hoʻohana ka hui noiʻi i ka ʻepekema helu no ka hōʻoia ʻana i ka mea hoʻoheheʻe kinoea a hōʻoia ʻaʻole e hoʻohālikelike ka hopena i nā waiwai uila o ka electrolyte. No laila, hiki ke hoʻolālā i ke kaʻina hana koʻikoʻi o ka pā uila proton ceramic.
"Me kēia noiʻi ʻana, ua kokoke mākou i ka hoʻomohala ʻana i ke kaʻina hana kumu nui no nā pihi seramika proton," i ʻōlelo ai nā mea noiʻi. Hoʻolālā mākou e aʻo i ke kaʻina hana o nā ʻāpana nui, kiʻekiʻe-efficiency proton ceramic batteries i ka wā e hiki mai ana. "
