Hiki ke hoʻokaʻawale ʻia nā wahie i lokoka membrane hoʻololi protonwahie wahie (PEMFC) a pololei methanol wahie keena e like me ka electrolyte waiwai a me ka wahie hoʻohana
(DMFC), phosphoric acid wahie cell (PAFC), molten carbonate fuel cell (MCFC), solid oxide fuel cell (SOFC), alkaline fuel cell (AFC), etc. maka membrane hoʻololi protonhoʻololi i ka proton medium, alkaline fuel cell (AFC) e hoʻohana i ka electrolyte wai-e like me ka solution potassium hydroxide e like me ka proton transfer medium, etc. Eia kekahi, e like me ka mahana hana, hiki ke hoʻokaʻawale ʻia nā wahie i nā pūnaewele wela wela a me ka wela haʻahaʻa. ʻO nā pūnaewele wahie, ʻo ka mua ka mea nui e pili ana i nā pūnaeau wahie oxide paʻa (SOFC) a me nā pūnaeau wahie carbonate i hoʻoheheʻe ʻia (MCFC). (AFC), phosphoric acid fuel cell (PAFC), etc.
ʻO ka membrane hoʻololi protonhoʻohana ʻia nā mea hoʻoheheʻe wahie (PEMFC) i nā membrane polymer acidic e like me kā lākou electrolytes. Pono nā pūnaewele PEMFC e hana ma lalo o ke kinoea hydrogen maʻemaʻe ma muli o ko lākou haʻahaʻa haʻahaʻa haʻahaʻa (ma lalo o 100 ° C) a me ka hoʻohana ʻana i nā electrodes metala hanohano (platinum based electrodes). Ke hoʻohālikelike ʻia me nā ʻāpana wahie ʻē aʻe, loaʻa iā PEMFC nā pōmaikaʻi o ka haʻahaʻa haʻahaʻa haʻahaʻa, ka wikiwiki o ka hoʻomaka ʻana, ka mana kiʻekiʻe, ka electrolyte non-corrosive a me ke ola lawelawe lōʻihi. No laila, ua lilo ia i ka ʻenehana mainstream i kēia manawa i hoʻohana ʻia i nā kaʻa kaʻa wahie, akā pili pū kekahi i nā hāmeʻa paʻa a paʻa. Wahi a E4 Tech, ua manaʻo ʻia ka hoʻouna ʻana o ka pahu wahie PEMFC i 44,100 mau ʻāpana ma 2019, e helu ana no 62% o ka māhele honua; ʻO ka mana i manaʻo ʻia e hiki i ka 934.2MW, ʻo 83% ka nui o ka honua.
Hoʻohana nā pūnaehu wahie i nā hopena electrochemical e hoʻololi i ka ikehu kemika mai ka wahie (hydrogen) ma ka anode a me ka oxidant (oxygen) ma ka cathode i uila e hoʻokele i ke kaʻa holoʻokoʻa. ʻO ke ʻano kikoʻī, ʻo nā ʻāpana koʻikoʻi o nā wahie he ʻōnaehana ʻenekini, lako mana kōkua a me ka moto; Ma waena o lākou, ʻo ka ʻōnaehana mīkini ka mea nui i ka mīkini i haku ʻia me ka reactor uila, ka ʻōnaehana mālama hydrogen kaʻa, ʻōnaehana hoʻomaha a me ka mea hoʻololi uila DCDC. ʻO ka reactor ka mea koʻikoʻi loa. ʻO ia kahi e hana ai ka hydrogen a me ka oxygen. Hoʻokumu ʻia ia i nā ʻāpana hoʻokahi i hoʻopaʻa ʻia, a ʻo nā mea nui e pili ana i ka pā bipolar, membrane electrode, end plate a pēlā aku.
