摘　　要：Ｐｔ是燃料电池中氢氧化所常用的一种催化剂。为了提高Ｐｔ的利用率，充分发挥Ｐｔ的催化性能，制备出高度分散、载量低的Ｐｔ／Ｃ催化剂。研究了Ｐｄ、Ｎｉ、Ｂｉ、Ｌａ对Ｐｔ／Ｃ催化剂的影响，并以各种催化剂制备成电极，测量了电极的极化曲线。发现Ｐｔ－Ｎｉ－Ｌａ／Ｃ是一种很好的氢电极催化剂。Platinum is a common catalyst used for hydrogen oxidation reaction in fuel cells.Pt/C catalyst was produced,in which platinum was highly dispersed and low loaded to increase operation rate and catalytic activities of platinum.The effects of Pd,Ni,Bi and La on Pt/C catalyst was researched.Some electrodes were produced with these catalysts and its polarization curves were measured.The results show that Pt Ni La/C is a good catalyst used for hydrogen oxidation in alkaline fuel cells.
