Claims

[Scope of utility model registration request]

(1) A pair of electrodes sandwiching an electrolyte matrix, a separator plate abutting the back surfaces of these electrodes, and an oxidant gas flowing along one back surface of the electrodes and a fuel gas flowing along the other back surface. In a fuel cell formed by stacking a plurality of unit cells each having a plurality of gas channels for circulation, and disposing a bus inlet manifold at one end of the gas channel and an outlet manifold at the other end, the inlet manifold 1. A stacked fuel cell characterized in that a plurality of openings of a manifold for supplying gas to the fuel cell are provided in a distributed manner so that gas flow rates from the openings are approximately the same.

(2) The stacked fuel cell according to claim 1, wherein the device for making the gas flow rate from the openings the same is a gas flow rate adjustment valve provided for each opening.

(3) The stacked fuel according to claim 2, wherein the gas flow rate adjustment valve provided for each opening is a flow rate adjustment valve that is controlled to have a set flow rate from each opening. battery.

(4) The flow rate adjustment valve, which is controlled to achieve the set flow rate from the opening, uses a flow meter to detect the gas flow rate, and calculates the adjustment amount by comparing the detected value of the gas flow rate with the set flow rate. 3. The stacked fuel cell according to claim 3, which is equipped with a regulator that transmits a signal, and a flow control valve that is operated by the signal from the regulator. −
