✦ Synopsis

We have adopted three different methods: dip-coating, brush pen painting, and ion-impregnating, to fabricate cathodes for anode-supported tubular solid oxide fuel cells; and studied the performances of the cells using cathodes fabricated by these three different methods. The cell with ion-impregnated cathode presented the best electrochemical performances in these three cells, and it generated a maximum power density of 446 mW cm -2 at 850 • C, when operating with humidified hydrogen. The cells with dipcoated cathode and brush pen painted cathode produced acceptable electrochemical performances; they generated maximum power densities of 403 and 405 mW cm -2 at 850 • C, respectively, when running on humidified hydrogen; also, they represented more stable, much easier processes and lower cost.
