Carbon-supported Pt-Ru composite catalysts, being active for dehydrogeno-aromatization of cyclohexane, have been elucidated to take an important role for the thermo-regenerative cyclohexane/benzene/hydrogen electrode as the cathode, which gave a neary theoretical magnitude of its open circuit voltage. The process of two electron transfer toward absorbed benzene was rate-determining, accompanied by two proton supply through the Nafion membrane. Our Pt-Ru composite electrode gave the current density 2.44 times larger than the conventional Pt electrode. Consequently, the catalyst design for both dehydrogenation and hydrogenation of the cyclohexane/benzene couple became prospective.

碳负载Pt-Ru复合催化剂具有环己烷脱氢芳构化活性，在热再生环己烷/苯/氢电极作为阴极中具有重要作用，其开路电压接近理论量级。两个电子向吸附苯转移的过程是速率决定的，并伴随着两个质子通过Nafion膜供应。我们的Pt- ru复合电极的电流密度是传统Pt电极的2.44倍。因此，环己烷/苯对的脱氢和加氢催化剂的设计是有前景的。
