PURPOSE:To make it possible to feed gas evenly to each unit cell of a unit cell laminated body and to gas circulation grooves of each unit cell, by forming a gas stay room with a partition board having numerous orifices, on the gas intake side of a gas feeding manifold. CONSTITUTION:When an oxidizer gas 13 flows into a gas stay room 15, the gas flow speed is reduced and the static pressure in the gas stay room 15 is increased. Therefore, through plural orifices 20 furnished on the upper side of the gas stay room 15, almost same flows of oxidizer gas 13 flow parallel along the side of a unit cell laminated body. Since the plural orifices 20 are arranged with almost same intervals along the whole flowing area of an oxidizer gas feeding manifold 17, almost even flow distribution from the lower side to the upper side in every section of the flowing route, without producing a local stagnation or an eddy current of the gas flow, can be acquired in the feeding manifold 17. |
