Waa maxay mabda'a gaadiidka unugyada shidaalka hydrogen?

Unugga shiidaalku waa nooc ka mid ah aaladaha wax-soo-saarka tamarta, kaas oo tamarta kiimikaad ee shidaalka u beddela tamar koronto iyada oo loo marayo falcelinta ogsajiinta ama oksaydhiyeyaasha kale.Shidaalka ugu caansan waa hydrogen, kaas oo loo fahmi karo falcelinta korantada biyaha ee hydrogen iyo oxygen.

Si ka duwan sida gantaalka, unugga shidaalka hydrogen ma soo saaro tamar dhaqdhaqaaqa iyada oo loo marayo falcelinta rabshadaha leh ee hydrogen iyo gubashada ogsijiinta, laakiin waxay sii daayaan Gibbs tamarta bilaashka ah ee hydrogen iyada oo loo marayo aaladda kicinta.Mabda'a shaqadeeda ayaa ah in hydrogen uu u kala go'o electrons iyo hydrogen ions (protons) iyada oo loo marayo kicinta (caadiyan platinum) ee korantada togan ee unugga shidaalka.Proton-yadu waxa ay ku gaadhaan korantada taban iyaga oo sii mara xuubka proton-ka waxana ay la falgalaan ogsijiin si ay u sameeyaan biyo iyo kulayl.Electron-yada u dhigma waxay ka soo qulqulayaan korantada togan ilaa korantada taban iyada oo loo marayo wareegga dibadda si loo dhaliyo tamar koronto.Ma laha wax kuleyl ah oo kuleyl ah oo ku saabsan 40% mashiinka shidaalka, waxtarka unugyada shidaalka hydrogen wuxuu si fudud u gaari karaa in ka badan 60%.

Horaantii dhowr sano ka hor, tamarta hydrogen waxaa loo yaqaan "qaabka ugu dambeeya" ee baabuurta tamarta cusub iyadoo loo eegayo faa'iidooyinka wasakheynta eber, tamarta dib loo cusboonaysiin karo, hydrogenation degdeg ah, baaxad buuxda iyo wixii la mid ah.Si kastaba ha ahaatee, aragtida farsamada ee unugga shidaalka hydrogen waa qumman yahay, laakiin horumarka warshadaynta ayaa si dhab ah dib u dhac u ah.Mid ka mid ah caqabadaha ugu waaweyn ee kor u qaadistiisa waa xakamaynta kharashka.Tan waxaa ku jira maaha oo kaliya qiimaha baabuurka laftiisa, laakiin sidoo kale qiimaha wax soo saarka hydrogen iyo kaydinta.

Horumarinta baabuurta unugyada hydrogen waxay ku xiran tahay dhismaha kaabayaasha shidaalka hydrogen sida wax soo saarka hydrogen, kaydinta hydrogen, gaadiidka hydrogen iyo hydrogenation.Si ka duwan taraamyada saafiga ah, kuwaas oo si tartiib tartiib ah loogu dallaci karo guriga ama shirkadda, baabuurta hydrogen waxaa lagu dalaci karaa oo kaliya saldhigga hydrogenation, sidaas darteed baahida loo qabo saldhigga dallacadu waa mid degdeg ah.Iyadoo aan lahayn shabakad dhamaystiran oo hydrogenation, horumarinta warshadaha baabuurta hydrogen waa wax aan macquul aheyn.
