PURPOSE: An on-planar type single chamber solid oxide fuel cell is provided to prevent the backward flowing of mixed gas from an anode to a cathode and to reduce voltage loss of an open circuit by maintaining oxygen partial pressure gradient. CONSTITUTION: An on-planar type single chamber solid oxide fuel cell comprises an electrolyte substrate(110), a fuel electrode(105) and an air electrode(100) which are arranged on the same plane as the substrate. The anode and cathode are arranged as a concentric form with a regular interval. The anode and cathode comprise a gasket with a pore identical to or smaller than the size of the cathode at a position corresponding the center cathode; and a gas guiding tube for guiding the mixed gas of fuel and gas to the center cathode. |
