Isahani ya bipolar plaque

Isahani ya Bipolar nigice cyibanze cya reaction, igira ingaruka zikomeye kumikorere nigiciro cya reaction. Kugeza ubu, isahani ya bipolar igabanijwemo cyane cyane isahani ya grafite, isahani ihuriweho hamwe n’icyuma ukurikije ibikoresho.

Isahani ya Bipolar ni kimwe mu bice by'ibanze bya PEMFC, uruhare rwayo nyamukuru ni ugutwara gaze binyuze mu murima utemba, gukusanya no kuyobora amashanyarazi, ubushyuhe n'amazi biterwa na reaction. Ukurikije ubwoko bwibikoresho, uburemere bwikibaho cya PEMFCs ni 60% kugeza 80% naho ikiguzi ni 30%. Ukurikije ibisabwa byimikorere ya plaque bipolar, kandi urebye ibidukikije bya aside irike ya PEMFC, isahani ya bipolar irasabwa kugira ibyangombwa byinshi kugirango amashanyarazi akoreshwe, gukomera kwikirere, imiterere yubukanishi, kurwanya ruswa, nibindi.

Isahani ibiri ukurikije ibikoresho ahanini bigabanijwemo ibyiciro bitatu isahani ya grafite, isahani igizwe, isahani yicyuma, icyapa cya kabiri ni cyo gikoreshwa cyane muri iki gihe icyapa cyo mu rugo cya PEMFC, icyuma gikoresha amashanyarazi, ubushyuhe bwumuriro, ituze ryiza hamwe no kurwanya ruswa nibindi bikorwa ariko ugereranije nubukanishi bubi, gucika intege, gukora imashini biganisha kubibazo byigiciro cyinshi byugarijwe nababikora benshi.

Igishushanyoisahani ya bipolarIntangiriro ：

Ibyapa bya bipolar bikozwe muri grafite bifite amashanyarazi meza, amashanyarazi yumuriro hamwe no kurwanya ruswa, kandi nibyuma bikoreshwa cyane muri PEMFCS. Nyamara, ibibi byayo nabyo biragaragara cyane: ubushyuhe bwo gushushanya bwa plaque ya grafite ubusanzwe burenga 2500 ℃, bugomba gukorwa hakurikijwe uburyo bwo gushyushya ubukana, kandi igihe ni kirekire; Igikorwa cyo gutunganya kiratinda, inzinguzingo ni ndende, kandi neza na mashini ni ndende, bivamo igiciro kinini cya plaque ya grafite; Graphite iroroshye, isahani irangiye igomba gukemurwa neza, guterana biragoye; Graphite irashashaye, isahani rero igomba kuba ifite milimetero nkeya kugirango imyuka itandukane, bikavamo ubucucike buke bwibikoresho ubwabyo, ariko nibicuruzwa biremereye.

Gutegura igishushanyoisahani ya bipolar：

Ifu ya toner cyangwa grafite ivangwa na resitifike, ikanda, kandi igashushanywa ku bushyuhe bwinshi (ubusanzwe kuri 2200 ~ 2800C) mukirere kigabanuka cyangwa mubihe bya vacu. Hanyuma, isahani ya grafite yatewe kugirango ifunge umwobo, hanyuma imashini igenzura imibare ikoreshwa mugutunganya gaze isabwa hejuru yayo. GUKORESHWA BY'AGATEGANYO N'IMIKORESHEREZE YO GUKORESHA GAZI NIMPAMVU Z'INGENZI Z'AMAFARANGA YISUMBUYE Y’IBIKORWA BYA BIPOLAR, HAMWE NA KUBARA MACHINING KUBARA hafi 60% by'AMAFARANGA AKURIKIRA.

Isahani ya bipolarni kimwe mubice byingenzi bigize lisansi ya selile. Ibikorwa byayo byingenzi ni ibi bikurikira:

1 connection Guhuza bateri imwe

2 、 Tanga lisansi (H2) n'umwuka (02)

3 collection Gukusanya hamwe nuyobora

4 、 Shigikira stack na MEA

5 Gukuraho ubushyuhe buterwa na reaction
