The analyses of the start-up process of a planar, anode-supported solid oxide fuel cell using three different start-up procedures

▸ Three start-up procedures for an anode-supported planar SOFC are investigated. ▸ The largest absolute temperature-gradient is exhibited in the early stage. ▸ The anode-recycling start-up procedure significantly reduces the start-up time. ▸ The fixed-temperature-difference procedure may reduce the temperature-gradient. ▸ The fixed-temperature-difference procedure also reduces the start-up time.
