520			\|a Abstract In this work, a highly active cathode with perovskite structure for solid oxide fuel cell (SOFC) is designed. The structural, chemical compatibility, and electrochemical properties of $ Sr_{2} %$ Fe_{1.5} %$ Mo_{0.5} %$ O_{6} $ partially doped with Cu ($ Sr_{2} %$ Fe_{1.5−x} %$ Cu_{x} %$ Mo_{0.5} %$ O_{6−δ} $, SFCxM) are investigated. The results show that SFCxM retains the perovskite structure when Fe element in $ Sr_{2} %$ Fe_{1.5} %$ Mo_{0.5} %$ O_{6} $ is partially replaced by Cu, but its unit cell expands as the doping amount of Cu increasing. The thermal expansion coefficient of $ Sr_{2} %$ Fe_{1.5} %$ Mo_{0.5} %$ O_{6} $ increases with Cu doping remarkably, so doping with excessive Cu is not conducive to the chemical compatibility between SFCxM cathode and samarium-doped ceria (SDC) electrolyte. Analysis of SFCxM cathode impedance data indicates that the properties of $ Sr_{2} %$ Fe_{1.5−x} %$ Cu_{x} %$ Mo_{0.5} %$ O_{6−δ} $ cathode can be improved by Cu substitution. The conductivity of $ Sr_{2} %$ Fe_{1.5} %$ Mo_{0.5} %$ O_{6} $ (SFM) is improved by doping with appropriate content of Cu, while the interface impedance of the SFCxM cathode decreases with Cu doping and reaches the smallest value of 0.26 Ω $ cm^{2} $ at the dopant content of x = 0.1. Furthermore, the interface impedance of the composite cathode consists of appropriate mass ratio of SFC0.1M, and SDC is lower than that of SFC0.1M. As a result, the composite cathode consists of appropriate mass ratio of SFC0.1M, and SDC is a potential cathode material for solid oxide fuel cell.

The structural, chemical compatibility, and electrochemical properties of $ Sr_{2} %$ Fe_{1.5} %$ Mo_{0.5} %$ O_{6} $ partially doped with Cu ($ Sr_{2} %$ Fe_{1.5−x} %$ Cu_{x} %$ Mo_{0.5} %$ O_{6−δ} $, SFCxM) are investigated. The results show that SFCxM retains the perovskite structure when Fe element in $ Sr_{2} %$ Fe_{1.5} %$ Mo_{0.5} %$ O_{6} $ is partially replaced by Cu, but its unit cell expands as the doping amount of Cu increasing. The thermal expansion coefficient of $ Sr_{2} %$ Fe_{1.5} %$ Mo_{0.5} %$ O_{6} $ increases with Cu doping remarkably, so doping with excessive Cu is not conducive to the chemical compatibility between SFCxM cathode and samarium-doped ceria (SDC) electrolyte. Analysis of SFCxM cathode impedance data indicates that the properties of $ Sr_{2} %$ Fe_{1.5−x} %$ Cu_{x} %$ Mo_{0.5} %$ O_{6−δ} $ cathode can be improved by Cu substitution. The conductivity of $ Sr_{2} %$ Fe_{1.5} %$ Mo_{0.5} %$ O_{6} $ (SFM) is improved by doping with appropriate content of Cu, while the interface impedance of the SFCxM cathode decreases with Cu doping and reaches the smallest value of 0.26 Ω $ cm^{2} $ at the dopant content of x = 0.1. Furthermore, the interface impedance of the composite cathode consists of appropriate mass ratio of SFC0.1M, and SDC is lower than that of SFC0.1M. As a result, the composite cathode consists of appropriate mass ratio of SFC0.1M, and SDC is a potential cathode material for solid oxide fuel cell.</subfield></datafield><datafield tag="700" ind1="1"

abstract	Abstract In this work, a highly active cathode with perovskite structure for solid oxide fuel cell (SOFC) is designed. The structural, chemical compatibility, and electrochemical properties of $ Sr_{2} %$ Fe_{1.5} %$ Mo_{0.5} %$ O_{6} $ partially doped with Cu ($ Sr_{2} %$ Fe_{1.5−x} %$ Cu_{x} %$ Mo_{0.5} %$ O_{6−δ} $, SFCxM) are investigated. The results show that SFCxM retains the perovskite structure when Fe element in $ Sr_{2} %$ Fe_{1.5} %$ Mo_{0.5} %$ O_{6} $ is partially replaced by Cu, but its unit cell expands as the doping amount of Cu increasing. The thermal expansion coefficient of $ Sr_{2} %$ Fe_{1.5} %$ Mo_{0.5} %$ O_{6} $ increases with Cu doping remarkably, so doping with excessive Cu is not conducive to the chemical compatibility between SFCxM cathode and samarium-doped ceria (SDC) electrolyte. Analysis of SFCxM cathode impedance data indicates that the properties of $ Sr_{2} %$ Fe_{1.5−x} %$ Cu_{x} %$ Mo_{0.5} %$ O_{6−δ} $ cathode can be improved by Cu substitution. The conductivity of $ Sr_{2} %$ Fe_{1.5} %$ Mo_{0.5} %$ O_{6} $ (SFM) is improved by doping with appropriate content of Cu, while the interface impedance of the SFCxM cathode decreases with Cu doping and reaches the smallest value of 0.26 Ω $ cm^{2} $ at the dopant content of x = 0.1. Furthermore, the interface impedance of the composite cathode consists of appropriate mass ratio of SFC0.1M, and SDC is lower than that of SFC0.1M. As a result, the composite cathode consists of appropriate mass ratio of SFC0.1M, and SDC is a potential cathode material for solid oxide fuel cell.
