Hiki i ka cell wahie hydrogen ke hoʻohana i nā ʻano wahie a me nā mea hānai like ʻole

Ua hoʻohiki nā ʻāina he nui i nā pahuhopu hoʻokuʻu ʻole net-zero i nā makahiki he ʻumi e hiki mai ana. Pono ka hydrogen e hoʻokō i kēia mau pahuhopu decarbonization hohonu. Ua manaʻo ʻia he 30% o nā hoʻokuʻu CO2 e pili ana i ka ikehu he paʻakikī ke hoʻopau me ka uila wale nō, e hāʻawi ana i kahi manawa kūpono nui no ka hydrogen. Hoʻohana kahi cell wahie i ka ikehu kemika o ka hydrogen a i ʻole nā ​​​​wahie ʻē aʻe e hana maʻemaʻe a me ka pono o ka uila. Inā ʻo ka hydrogen ka wahie, ʻo nā huahana wale nō ka uila, ka wai, a me ka wela.Nā pūnaewele wahiehe kū hoʻokahi ma ke ʻano o nā ʻano hana like ʻole; hiki iā lākou ke hoʻohana i kahi ākea o nā wahie a me nā mea hānai a hiki ke hāʻawi i ka mana no nā ʻōnaehana nui e like me ke kahua mana pono a liʻiliʻi e like me kahi kamepiula lawe lima.

ʻO kahi cell wahie he cell electrochemical e hoʻololi i ka ikehu kemika o kahi wahie (pinepine hydrogen) a me kahi mea oxidizing (pinepine oxygen) i uila ma o kahi pālua o nā hopena redox. He ʻokoʻa nā cell wahie mai ka hapa nui o nā pila ma ke koi ʻana i kahi kumu hoʻomau o ka wahie a me ka oxygen (mai ka ea) e hoʻomau i ka hopena kemika, ʻoiai i loko o kahi pila ka ikehu kemika e hele mai ana mai nā metala a me kā lākou ions a i ʻole oxides [3] i loaʻa mua i loko o ka pila, koe wale nō i nā pila kahe. Hiki i nā cell wahie ke hana i ka uila mau no ka lōʻihi o ka hoʻolako ʻia ʻana o ka wahie a me ka oxygen.

ʻO kekahi o nā ʻāpana nui o ka cell wahie hydrogenpapa Bipolar graphiteI ka makahiki 2015, ua komo ʻo VET i ka ʻoihana cell wahie me kona mau pono o ka hana ʻana i nā papa electrode wahie graphite. ʻO ka hui i hoʻokumu ʻia ʻo Miami Advanced Material Technology Co., LTD.

Ma hope o nā makahiki o ka noiʻi a me ka hoʻomohala ʻana, ua loaʻa i nā kauka holoholona ka ʻenehana kūpono no ka hana ʻana i 10w-6000wNā pūnaewele wahie hydrogenKe hoʻomohala ʻia nei ma luna o 10000w mau hunaola wahie i hoʻoikaika ʻia e ke kaʻa e kōkua i ke kumu o ka mālama ʻana i ka ikehu a me ka palekana o ke kaiapuni. No ka pilikia nui o ka mālama ʻana i ka ikehu hou, ke hōʻike nei mākou i ka manaʻo e hoʻololi ka PEM i ka ikehu uila i hydrogen no ka mālama ʻana a hoʻopuka ka hunaola wahie hydrogen i ka uila me ka hydrogen. Hiki ke hoʻopili ʻia me ka hana mana photovoltaic a me ka hana hydropower.
