Cathodes for fuel cells.....

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 (M. Liu et al, April 2; Adv. Mater. 2002, 14, 521-523).
