huahana

ʻO kahi hunaola wahie kahi aila electrochemical e hoʻohuli i ka ikehu kemika o kahi wahie (pinepine ka hydrogen) a me kahi mea hana oxidizing (pinepine oxygen) i loko o ka uila ma o ka pālua o nā hopena redox. He ʻokoʻa nā aila wahie mai ka hapanui o nā paila i ke koi ʻana i kahi kumuwaiwai mau o ka wahie a me ka oxygen (maʻa mau mai ka ea) e hoʻomau ai i ka hopena kemika, akā i loko o kahi paila e hele pinepine ka ikehu kemika mai nā metala a me kā lākou iona a i ʻole nā ​​oxide i loaʻa mau i ka o nā puʻukū, koe wale nō i nā paila kahe. Hiki i nā hunaola wahie ke hana i ka uila mau no ka mea ke hāʻawi ʻia ka wahie a me ka oxygen.

Nui a hewahewa ke ʻano o nā hunaola wahie, akā he anode, he cathode, a me kahi electrolyte e ʻae ai i nā iona, e hoʻoili pinepine i nā ion hydrogen (protons), e neʻe ma waena o nā ʻaoʻao ʻelua o ka cell wahie. Ma ke anode he catalyst e kumu i ka wahie e hana i nā hopena o ka hoʻohaʻahaʻa e hoʻoulu i nā ion (ʻo ka hydrogen ion i kauoha ʻia me ka maikaʻi) a me nā electrons. Holo nā ion i ke anode i ka cathode ma o ka electrolyte. I ka manawa like, kahe nā electrons mai ka anode i ka cathode ma o ka puni waho, e hana ana i ka uila o kēia manawa. Ma ka cathode, kekahi mea hōʻeuʻeu e kumu i nā ion, electron, a me oxygen e hana, hana i ka wai a me nā huahana ʻē aʻe. Hoʻokaʻawale ʻia nā hunaola wahie e ke ʻano o ka electrolyte a lākou e hoʻohana ai a me ka ʻokoʻa i ka manawa hoʻomaka mai ka 1 kekona no nā hunaola wahie membrane proton-exchange (PEM wahie cells, a i ʻole PEMFC) i 10 mau minuke no nā hunaola wahie paʻa (SOFC).
Hāʻawi mākou i nā lawelawe hoʻonohonoho huahana, mai ka ʻumi mau watts o nā puʻu lawe liʻiliʻi liʻiliʻi, nā haneli he mau watts o nā kaʻa uila a i ʻole nā ​​drone stacks, kekahi mau kilowatts o nā forklift stack, a me nā kekala o nā kilowatts o nā kaʻa kauō kaumaha. Hana lawelawe kikoʻī.

ʻO ka ʻōnaehana hana hydrogen, ʻōnaehana mālama hydrogen, ʻōnaehana hoʻolako hydrogen, hoʻonohonoho uila, kahi hoʻonohonoho holoʻokoʻa o nā ʻōnaehana i kahi lawelawe kū hoʻokahi.
