PROBLEM TO BE SOLVED: To suppress degradation of drainage performance of a reaction gas exhaust manifold of a fuel battery.SOLUTION: A fuel battery system comprises a fuel battery, a supply manifold provided to extend into the fuel battery along a lamination direction, an exhaust manifold which is located above the supply manifold in a gravity direction to extend into the fuel battery along the lamination direction, an exhaust blow execution part for executing exhaust blow, and a gas supply amount controller for controlling the flow rate of reaction gas to be supplied to the fuel battery to be larger than that under normal operation of the fuel battery and also smaller than that under blow execution in at least one of a case where the operation environment of the fuel battery is a multi-water operation environment that the water reservoir amount in the exhaust manifold may be larger than that under the normal operation and a case where the operation condition of the fuel battery is a multi-water operation condition that the water reservoir amount in the exhaust manifold may be larger than that under the normal operation.SELECTED DRAWING: Figure 1 |
