Bipolar daim hlau(BPs) yog ib feem tseem ceeb ntawmProton exchange membrane (PEM)roj hlwb nrog multifunctional cim. Lawv ua tib zoo faib cov pa roj thiab cua, ua hluav taws xob tam sim no los ntawm lub xov tooj ntawm tes mus rau ntawm tes, tshem tawm cov cua sov los ntawm qhov chaw ua haujlwm, thiab tiv thaiv kom tsis txhob muaj cov pa phem thiab cov dej txias. BPs kuj tseem txhawb nqa qhov ntim, qhov hnyav thiab tus nqi ntawm PEMroj cell stacks.
Bipolar daim hlaucais cov reactant gases thiab faib rau txhua sab ntawm tag nrho cov active cheeb tsam ntawm MEA. Cov phaj bipolar kuj tshem tawm cov pa roj thiab dej tsis muaj zog los ntawm thaj chaw ua haujlwm ntawm MEA. Cov phaj bipolar yuav tsum yog cov khoom siv hluav taws xob, muaj tshuaj lom neeg tiv taus rau kev ua haujlwm, thiab thermally conductive kom zoo dua kub hloov mus rau hauv lub cell. Cov phaj bipolar rau LT- thiab HT-PEMFCs yog tsim los ntawm yuav luag tib cov ntaub ntawv, tab sis HT-PEMFC bipolar phaj cov khoom yuav tsum ua kom muaj hluav taws xob tsis tu ncua, ib puag ncig pH qis thiab kub txog li 200 ° C. Nws yuav tsum tau hais tias cov phaj bipolar yog hluav taws xob thiab thermally conductive.
Qee qhov haujlwm no suav nrog kev faib cov roj thiab oxidant hauv cov hlwb, kev sib cais of qhov sib txawv ntawm lub hlwb, kev sau ntawm cov hluav taws xob tam sim no, kev khiav tawm ntawm cov dej los ntawm txhua lub xov tooj ntawm tes, humidification ntawm gases thiab cua txias ntawm lub hlwb. Bipolar daim hlau kuj tseem muaj cov channel uas tso cai rau kev nkag mus ntawm cov reactants (roj thiab oxidant) ntawm txhua sab. Lawv tsim cov anode thiab cathode compartments nyob rau sab nraud ntawm lub phaj bipolar. Qhov tsim ntawm cov dej ntws tuaj yeem sib txawv; lawv tuaj yeem yog linear, coiled, parallel.
VET yog lub phaj bipolarmanufacturer uas tshwj xeeb hauv kev ua haujlwm siab kev cai roj cell Cheebtsam raucov tuam txhab tsim khoom, cov kws tshawb fawb thiab cov kws qhia ntawv thoob ntiaj teb.Peb tau tsim cov nqi-zoo graphite bipolar daim hlau rauRoj Cell(PEMFC) uas yog qib siab bipolar daim hlau uas muaj hluav taws xob ua tau zoo thiab lub zog zoo txhua yam. Cov phaj bipolar tso cai rau cov roj hlwb ua haujlwm ntawm qhov kub thiab txias thiab muaj hluav taws xob zoo heev thiab thermal conductivity.
