Tuning an ionic-electronic mixed conductor NdBa0.5Sr0.5Co1.5Fe0.5O5+δ for electrolyte functions of advanced fuel cells

Synthesis and ionic conductivity of calcium-doped ceria relevant to solid oxide fuel cell applications

“…Although recently, Schottky junction (SJ) based n or p-type low-cost semiconductor -ionic conductor composite materials have shown potential to cause in-filed barriers and confine the electron's mobility or holes from the passage of the electrolyte edge to the opposite side. Thus, preventing the short-circuiting in the SOFCs and may be accountable for the colossal ionic conductivity [11][12][13][14][15][16][17][18][19][20][21][22]. But still, there is scanty work related to the Ca-doped ceria framework for IT-SOFCs.…”

“…Thus, this prevents the short-circuiting in the SOFCs and may be accountable for the colossal ionic conductivity. [11][12][13][14][15][16][17][18][19][20][21][22] Still, there are few studies related to the Ca-doped ceria framework for IT-SOFCs. From the point of the ionic-radius, compatibility of the dopant, commercial viability, and abundant nature, calcium (Ca) has been picked as a dopant for the host cerium cross-section.…”
