據http://fuelcellsworks.com/報道：德國魯爾大學電化學科學中心和馬克斯-普朗克學會的研究人員共同報道了一種新型概念燃料電池(FC)催化劑，采用氧化還原水凝膠作(zuo)為(wei)緩(huan)衝(chong)劑(ji)，能(neng)夠(gou)在(zai)燃(ran)料(liao)電(dian)池(chi)反(fan)應(ying)中(zhong)防(fang)止(zhi)催(cui)化(hua)劑(ji)氧(yang)化(hua)過(guo)程(cheng)的(de)發(fa)生(sheng)，從(cong)而(er)避(bi)免(mian)催(cui)化(hua)劑(ji)活(huo)性(xing)下(xia)降(jiang)，同(tong)時(shi)具(ju)有(you)便(bian)宜(yi)高(gao)效(xiao)的(de)優(you)點(dian)，相(xiang)關(guan)文(wen)章(zhang)已(yi)發(fa)表(biao)在(zai)自(zi)然(ran)化(hua)學(xue)雜(za)誌(zhi)上(shang)。該種新型概念燃料電池采用的氫化酶催化劑，它是一種從自然界中獲取的氫氧化生物催化劑，製備中僅僅利用生物有機體中的元素，沒有任何貴金屬成分。複合的氫化酶由鎳、鐵等含量豐富的元素構成，氫化酶的最高催化效率和金屬鉑相當。因此，氫化酶是貴金屬的潛在替代物。
