Japanese Patent JP7472805
Kind Code:
B2
Abstract:
To appropriately supply reforming water with a simple configuration that suppresses an increase in cost.SOLUTION: A fuel cell system includes: a reformer that reforms raw fuel gas to generate reformed gas; a water tank that stores reforming water used for reforming the reformer; a water pump that discharges the reforming water in the water tank to a supply pipe for supplying the water to the reformer; a flow sensor that detects the flow rate of the reforming water flowing through the supply pipe; a drain valve that is configured as a diaphragm-type solenoid valve, is connected between the water pump and the flow sensor and to the water tank, and discharges the reforming water to the water tank by opening the valve; and a control device that can perform water supply control for supplying the reforming water by closing the drain valve and driving the water pump by feedback control based on the flow rate detected by the flow sensor, and drainage control for discharging the reforming water in the supply pipe by opening the drain valve when the system is stopped.SELECTED DRAWING: Figure 1
