燃料電池システム
Document Type and Number:
Japanese Patent JP6409368
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve operation efficiency of a fuel cell system comprising a hot water storage tank, by suppressing collapse of thermal stratification in stored hot water in the hot water storage tank.SOLUTION: A fuel cell system 100 includes: a bubble generation determination unit (controller 15) for determining whether or not bubbles have been generated in a heat exchanger 12, on the basis of a temperature T2 detected by a second temperature sensor 12e; a bubble discharge unit (controller 15) for executing bubble discharge control of discharging bubbles from the heat exchanger 12 by making a flow rate of stored hot water to be discharged from a circulation pump 22a be greater than that at the time of determining the generation of the bubbles, when it is determined that the bubbles have been generated in the heat exchanger 12; and a temperature increasing unit (controller 15) for executing temperature increasing control of making a temperature of stored hot water to be discharged from the heat exchanger 12 be greater than that at the time of determining the generation of the bubbles, by adjusting the flow rate of stored hot water to be discharged from the circulation pump 22a after the execution of the bubble discharge control.
