Hoʻokumu maikaʻi ka hui HKU i "ke kila kila no ka hana hydrogen"

ʻO ke kila kila ka abbreviation o ke kila ʻakika kūpaʻa. Ua kapa ʻia nā ʻano kila i kū ʻole i nā media corrosive nāwaliwali e like me ka ea, ka mahu, a me ka wai a i ʻole ke kila kila. ʻAʻole pili wale ka huaʻōlelo "stainless steel" i hoʻokahi ʻano kila kila, akā e pili ana i ka ʻoi aku ma mua o hoʻokahi haneli mau kila kila kila, ua hoʻomohala ʻia kēlā me kēia mea e loaʻa ka hana maikaʻi ma kāna kahua noi kikoʻī.

ʻO ke kila kila he mea hao kūikawā nona nā mea nui i loko o ka hao, chromium, nickel, molybdenum a me nā mea ʻē aʻe. ʻO nā lakio like ʻole a me nā mea like ʻole o kēia mau mea e hoʻoholo ai i nā waiwai a me ka hoʻohana ʻana i ke kila kila. I kēia manawa e hoʻolauna aku wau iā ʻoe i kahi ʻano kila kila kūikawā hou.

Ua holomua ka hui o Polofesa Huang Mingxin mai ke Keʻena ʻEnekinia Mechanical o ke Kulanui o Hong Kong i "ke kila kila no ka hana hydrogen". ʻOi aku ka maikaʻi o kona kūpaʻa ʻana i ka wai paʻakai a me ka hana ʻana o ka hydrogen ma mua o ke kila kila kuʻuna. Inā hoʻohana ʻia i ka ʻoihana, e hoʻemi nui ia i ke kumukūʻai o ka hana hydrogen ma o ka electrolyzing i ka wai kai, a laila hāʻawi i ka hydrogen Hāʻawi i ka hoʻomohala ʻana i ka ʻoihana ikehu a me ka hoʻokō ʻana i ka piko kalapona a me ka neutrality carbon.

Ua hoʻomaopopo ʻia ʻo ka hoʻohana ʻana i kēia manawa i ka wai kai desalinated a i ʻole nā ​​​​mea ʻawaʻawa e hana ai i ka hydrogen e hoʻohana pinepine i nā mea titanium maʻemaʻe i hoʻopaʻa ʻia i ke gula a i ʻole platinum-plated e like me nā mea hana hale electrolytic cell. I kēia manawa, ʻo ke kumukūʻai holoʻokoʻa o nā lako electrolyzer PEM me ka mana o 10 MW ma kahi o HK $ 17.8 miliona, ʻo ia ka nui o ke kumu kūʻai o nā ʻāpana i hiki ke kiʻekiʻe me 53%. ʻO ke kila kila hou i hoʻomohala ʻia e ka hui ʻo Professor Huang Mingxin e hoʻemi ʻia ke kumukūʻai o nā mea hana ma kahi o 40 mau manawa.

Hiki i ka "Stainless steel for hydrogen production" ke hana pololei i ka hydrogen i loko o ka wai paʻakai, a hiki ke hoʻololi i nā ʻāpana structural titanium maʻemaʻe, e hana ana i ke kumu kūʻai o nā ʻāpana hana i nā manawa he nui, e hāʻawi ana i kahi ʻenehana hana wai kai hydrogen e kū nei i loko. pae noiʻi a hoʻomohala. s hoʻonā.

Ua paʻi ʻia ka pepa noiʻi o kēia manawa ma Materials Today. Ke noi nei ʻo "Stainless steel for hydrogen production" i nā patent multi-national, ʻelua o ia mau mea i ʻae ʻia, a ua hōʻike nā hui hydrogen ikehu i ka hoihoi i ka hui pū ʻana.
