AI Technical Summary
Existing solid oxide fuel cells (SOFCs) using electrolyte materials with proton conductivity face a demand for electrode materials that can exhibit excellent performance at lower operating temperatures and reduce reaction resistance.
The development of an electrode material represented by the chemical formula BaZr1-x-yMxCo yO3-δ, where M is In or Yb, and x, y, and δ satisfy specific conditions, which enhances proton conductivity and reduces reaction resistance, allowing for efficient operation at temperatures around 500°C to 600°C.
The proposed electrode material demonstrates lower reaction resistance and improved performance as an electrode, particularly in SOFCs with proton-conductive electrolyte membranes, increasing the efficiency and output of fuel cells.
