中文摘要：
用四氢呋喃（THF）络合还原法制备了直接甲醇燃料电池（DMFC）阴极用Ir-Ru／C催化剂，研究了n（Ir）：n（Ru）对Ir-Ru／C催化剂对氧还原的电催化活性和抗甲醇能力的影响。当n（Ir）：n（Ru）=3：1时，Ir-Ru／C催化剂具有很好的抗甲醇能力，对氧还原的电催化活性好于n（Ir）：n（Ru）=1：1和2：1时，也好于Ir／C催化剂和Ru／C催化剂。
英文摘要：
Ir-Ru/C catalyst for the cathode of direct methanol fuel cell （DMFC） was prepared by tetrahydrofuran （THF） complexing reduction method. The effects of n（Ir） ： n（Ru） to electrocatalytic activity for the oxygen reduction and the methanol tolerance ability of Ir-Ru/C catalysts were studied. The Ir-Ru/C catalyst with n （Ir） ： n （Ru） = 3 ： 1 had fine methanol tolerance ability, its electrocatalytic activity for the oxygen reduction was better than that of which n （Ir） ： n （Ru） = 1 ： 1 and 2 ： 1,it was also better than that of Ir/C catalyst and Ru/C catalyst.
