GDE氣體(ti)擴散(san)電(dian)(dian)(dian)極(ji)是一種(zhong)重要(yao)的(de)(de)(de)(de)(de)材(cai)(cai)料(liao)，在電(dian)(dian)(dian)化(hua)學領域中(zhong)廣泛應(ying)(ying)用(yong)于電(dian)(dian)(dian)解池等系統中(zhong)。在制備(bei)GDE氣體(ti)擴散(san)電(dian)(dian)(dian)極(ji)測試電(dian)(dian)(dian)解池時，需(xu)要(yao)考(kao)慮以下幾個(ge)關鍵問題(ti)和(he)(he)技(ji)術難點。首先，選擇(ze)合適的(de)(de)(de)(de)(de)基(ji)底材(cai)(cai)料(liao)非常重要(yao)。GDE氣體(ti)擴散(san)電(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)(de)基(ji)底材(cai)(cai)料(liao)應(ying)(ying)具有良好的(de)(de)(de)(de)(de)導(dao)(dao)電(dian)(dian)(dian)性(xing)(xing)、化(hua)學穩定性(xing)(xing)和(he)(he)機械強(qiang)度。通常使用(yong)碳纖維布(bu)或碳紙作為基(ji)底材(cai)(cai)料(liao)，其(qi)高導(dao)(dao)電(dian)(dian)(dian)性(xing)(xing)和(he)(he)良好的(de)(de)(de)(de)(de)抗腐(fu)蝕性(xing)(xing)能使其(qi)成(cheng)為理想的(de)(de)(de)(de)(de)選擇(ze)。其(qi)次，催(cui)化(hua)劑的(de)(de)(de)(de)(de)選擇(ze)和(he)(he)負載也是制備(bei)GDE氣體(ti)擴散(san)電(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)(de)關鍵問題(ti)。催(cui)化(hua)劑的(de)(de)(de)(de)(de)種(zhong)類和(he)(he)負載量會直接影響電(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)(de)活性(xing)(xing)和(he)(he)穩定性(xing)(xing)。常見的(de)(de)(de)(de)(de)催(cui)化(hua)劑包括(kuo)鉑、鉑合金等，...
