Performance of an Anode-supported Solid Oxide Fuel Cell in a Mixed-gas Configuration

摘要

Thin films of Samaria-Doped Ceria (SDC) were formed on porous substrates using screen printing and within the pores of electrodes using a sol-gel coating method. The SDC-electrolyte film, with a controllable thickness of less than 20 μm, was bound tightly to the anode substrate. The maximum power density of the single cells was 375 mW cm~(-2) at 650℃ with a 25% methane in mixed gas mixture. The long-term stability of the cell as well as the effects of flow rate, gas composition, fuel type, etc. on the cell performance will be continuously studied to get the optimization of operating conditions.
