摘要
We prepared a new functional composite consisting of natural Cu Fe-oxide mineral(CF) and a good oxygen ion conducting LiZnO_2-Sm_(0.2)Ce_(0.8)O_(2-δ)(LZSDC).This material was first investigated as a novel electrolyte material for low-temperature solid oxide fuel cells(SOFCs).The CF-LZSDC composite was synthesized via a solid-state reaction method.Using a CF-LZSDC as an electrolyte layer between the symmetric electrodes of Ni_(0.8)Co_(0.2)Al_(0.5)Li(NCAL) coated Ni foam.The relation between the electrolyte microstructure and compaction pressure was investigated.The results showed that the density of the electrolyte increased with the increasing compaction pressure,and the optimum density contributed to the highest power output and the lowest ohmic resistance.The device pellet with an active area of 0.64 cm~2 under a compaction pressure of 10 MPa shows the highest power density of 637 mW cm~(-2) at 550 °C.We also studied electrochemical catalyst functions by applying the CF for anode and cathode respectively.Novel ion-conduction and function mechanisms are proposed for developments of natural minerals for advanced fuel cell applications.
