Cov khoom siv hluav taws xob yog dab tsi
Apr 25, 2021
Cov khoom siv hluav taws xob muaj feem ntau suav cov hnub ci cell xov tooj, cov ntaub ntawv khaws cia hydrogen, thiab cov khoom siv roj teeb oxide.
Cov ntaub ntawv hauv nruab hnub ci yog cov ntaub ntawv tshiab ntawm lub zog. Qhov sib txuam ntau txheej hnub ci hlwb tsim los ntawm IBM muaj qhov hloov pauv ntawm mus txog 40%.
Hydrogen yog qhov zoo tshaj plaws lub zog tsis muaj kuab paug thiab siab ua kom tau zoo. Tus yuam sij rau kev siv hydrogen yog qhov cia thiab thauj ntawm hydrogen. Kwv yees li 50% ntawm Asmeskas Lub Tsev Haujlwm Saib Xyuas Lub Zog' s kev tshawb nrhiav hydrogen rau kev siv nyiaj yog siv rau kev khaws cia hydrogen. Hydrogen yuav corrode cov khoom siv dav dav, ua rau hydrogen embrittlement thiab dej xau, thiab tseem tawg thaum lub sijhawm kev thauj mus los. Cov txheej txheem hydrogen khaws cia ntawm cov khoom siv hydrogen ua ke tuaj yeem ua ke nrog hydrogen ua cov npliag dej. Thaum xav tau, rhaub nws kom tso tawm hydrogen. Cov ntaub ntawv uas tuaj yeem txuas ntxiv raug them nrog hydrogen. Cov khoom siv hluav taws xob hydrogen khaws cov khoom siv hlau feem ntau. Xws li LaNi5H, Ti1.2Mn1.6H3 thiab lwm yam.
Kev tshawb fawb ntawm cov khoom siv roj oxide roj hlwb yog qhov nquag nquag. Qhov tseem ceeb yog cov khoom siv roj teeb, xws li cov khoom hluav taws xob zoo hluav taws xob thiab cov roj teeb cathode, ntxiv rau cov organic proton pauv membranes rau proton pauv membrane roj hlwb.
