分體(ti)式集成(cheng)(cheng)電(dian)(dian)堆(dui)主要(yao)由質子交換膜(mo)燃料電(dian)(dian)池組與Nafion○R115膜(mo)加濕器(qi)組成(cheng)(cheng)，目前(qian)PEMFC電(dian)(dian)堆(dui)普(pu)遍采用流場(chang)板、密封(feng)件和膜(mo)電(dian)(dian)極構成(cheng)(cheng)的電(dian)(dian)池單元串接而成(cheng)(cheng)

分(fen)(fen)體(ti)式(shi)集成電(dian)(dian)(dian)堆(dui)(dui)主(zhu)要由質子交換膜燃(ran)料電(dian)(dian)(dian)池(chi)組與(yu)Nafion○R115膜加(jia)(jia)(jia)濕器組成，目前(qian)PEMFC電(dian)(dian)(dian)堆(dui)(dui)普遍采用(yong)(yong)流場板(ban)、密(mi)封件和膜電(dian)(dian)(dian)極(ji)(ji)構成的(de)電(dian)(dian)(dian)池(chi)單(dan)元(yuan)串接 而成。每個電(dian)(dian)(dian)池(chi)單(dan)元(yuan)均(jun)有各自(zi)獨立的(de)進、出氣(qi)(qi)口(kou)。各電(dian)(dian)(dian)池(chi)單(dan)元(yuan)中相應的(de)氣(qi)(qi)路并接到總氣(qi)(qi)管上。分(fen)(fen)體(ti)式(shi)集成電(dian)(dian)(dian)堆(dui)(dui)與(yu)傳統(tong)集成電(dian)(dian)(dian)堆(dui)(dui)的(de)區別主(zhu)要在于(yu)：膜加(jia)(jia)(jia)濕器獨立于(yu)電(dian)(dian)(dian)池(chi) 組外(wai)，能靈活(huo)安裝(zhuang)與(yu)調(diao)節(jie)，而且(qie)還能用(yong)(yong)電(dian)(dian)(dian)堆(dui)(dui)冷卻水直接加(jia)(jia)(jia)濕反(fan)應氣(qi)(qi)體(ti)。共同之處是：兩種(zhong)類型(xing)的(de)電(dian)(dian)(dian)堆(dui)(dui)在雙極(ji)(ji)板(ban)間均(jun)放(fang)置了冷卻板(ban)，用(yong)(yong)于(yu)調(diao)節(jie)電(dian)(dian)(dian)堆(dui)(dui)溫度。
