Abstract [en]

The performance of low temperature solid oxide fuel cells fabricated by hot-pressing technology was studied at temperatures below 650°C. The cells consisted of Ce0.8Sm0.2O1.9-salt (Li2CO3+Na2CO3) composite electrolyte, Ni anode, lithiated NiO cathode and Ni-net current collectors. For a reported cell here, the open-circuit voltages were 0.863 and 0.873 V, the measured maximum power densities were 0.615 and 0.743 mW·cm-2 at 600 and 650°C, respectively. In the best case, the OCV of hot-pressed fuel cell reached 1.006 V (650°C) with higher performance. The performance is significantly improved compared to those fabricated by cold pressing.
