PURPOSE:To level current density distribution and to increase power generation efficiency by passing reaction gasses so that they form plural flows having mutually opposite directions, and separating the adjacent opposite flows each other with a separating wall. CONSTITUTION:A plurality of unit cells comprising a pair of electrode plates faced with an electrolyte plate interposed are stacked via a separator, and reaction gas is passed between the electrode plate and the separator to form a fuel cell. A gas separating wall 3 is arranged on a cathode 11 side, and a gas separating wall 13 on an anode 12 side. Fuel gas 14 is divided into two flows with the separating wall 3 and its flow is made opposite each other, and oxidizing gas 15 is also divided into two opposite flows. Plural parts having high current density are formed to level current density distribution. Therefore, cell performance is stabilized and power generating efficiency is increased. |
