Phaj Graphite Qib Roj Cell, Phaj Carbon bipolar

Cov khoom siv graphite yog cov khoom siv phaj bipolar uas tau tsim thiab siv ua ntej. Cov phaj bipolar ib txwm siv cov phaj graphite uas tsis muaj qhov, thiab cov grooves raug ua tiav los ntawm kev siv tshuab. Cov phaj bipolar graphite muaj cov coefficient nthuav dav thermal qis, cov thermal conductivity zoo, cov khoom siv tshuaj ruaj khov, tiv taus corrosion zoo thiab cov hluav taws xob muaj zog. Txawm li cas los xij, qhov brittleness ntawm graphite ua rau muaj teeb meem hauv kev ua, thiab tib lub sijhawm txwv tsis pub txo qhov tuab ntawm phaj graphite, thiab nws yooj yim los tsim cov qhov thaum lub sijhawm tsim khoom, yog li cov roj thiab cov oxidant tuaj yeem nkag mus rau ib leeg, yog li lwm yam tshuaj yuav tsum tau ntxiv los txhim kho kev ua haujlwm ntawm lub roj teeb.

Peb tau tsim cov phaj graphite bipolar uas pheej yig rau PEMFC uas xav tau kev siv cov phaj bipolar siab heev uas muaj kev ua hluav taws xob siab thiab lub zog zoo. Peb cov phaj bipolar tso cai rau cov roj cell ua haujlwm ntawm qhov kub siab thiab muaj kev ua hluav taws xob thiab thermal zoo heev.

Peb muab cov khoom siv graphite nrog cov resin impregnated kom ua tiav cov pa roj tsis nkag thiab muaj zog. Tab sis cov khoom siv khaws cov khoom zoo ntawm graphite hauv cov nqe lus ntawm kev ua hluav taws xob siab thiab kev ua kom sov siab.

Peb tuaj yeem siv tshuab ua cov phaj bipolar rau ob sab nrog cov teb ntws, lossis siv tshuab ib sab lossis muab cov phaj dawb uas tsis tau siv tshuab. Txhua daim phaj graphite tuaj yeem siv tshuab raws li koj tus qauv tsim.
