Activation of SDC Anode with Highly-Dispersed Ni Electrocatalysts

Activation of SDC Anode with Highly-Dispersed Ni Electrocatalysts 

We have examined the possibility to enhance the anode performance by dispersing inexpensive metal catalysts on die SDC. As shown in Fig. 4, the SDC was not sufficiently activated by nm-sized Ni catalysts with an amount of 0.1 mg/cni ca. 1 vol%). However, higher Ni loading can be allowed to improve the performance, because Ni is much cheaper than Ru by ca. 1/40. We have found that 6 to 8 vol% of Ni nanoparticles (Jni = ca. 20 nm) enlianced the SDC anode performance significantly at 7 ceu = 700 to 800°C in humidified A typical performance is shown by A symbol in
