• Fuel cell
• Lithium nickel oxide (LiNiO(2))
• Gadolinium doped ceria (GDC)
• Single component

A fuel cell device is realized by using a single component of lithium nickel oxide and gadolinium doped ceria (LiNiO(2)-GDC) composite material, a mixture of electronic and ionic conductors, when nickel foam and silver paste are attached to each surface of the single component pellet as current collectors. This simple fuel cell construction with only one component showed the same or even better performances compared to conventional three-component MEA (membrane electrolyte assembly) fuel cell using GDC as electrolyte. The maximum power density of 450 mW/cm(2) has been achieved at 550 degrees C for the single component fuel cell.
