A solid‐oxide fuel cell that operates at 500 °C (instead of 600 °C and higher), with lower material cost and better long‐term stability, is presented. Its key piece is a cathode made of a silver/copper‐doped bismuth vanadate (Ag‐BICUVOX) composite, which reduces oxygen at lower temperatures and diminishes the resistance between the cathode and the electrolyte. The Figure shows an SEM cross section of the described cell.
