FUEL CELL SYSTEM
Document Type and Number:
Japanese Patent JP2020135956
Kind Code:
A
Abstract:
To provide a technology capable of securing silence depending on a user's desire.SOLUTION: A fuel cell system performing warm-up operation having a normal warm-up operation mode and a low speed warm-up operation mode comprises: a fuel cell stack; a compressor; a temperature measurement section for acquiring a stack temperature; and a control section that in the warm-up operation, controls output voltage to a predetermined voltage until the stack temperature rises to a predetermined first threshold temperature and controls a cathode gas supply amount to a predetermined supply amount. When the low speed warm-up operation mode is selected, the control section controls the output voltage to a second voltage higher than a first voltage in the normal warm-up operation mode until the stack temperature rises from the first threshold temperature to a second threshold temperature and controls the cathode gas supply amount to a second supply amount smaller than a first supply amount in the normal warm-up operation mode and, when a request for terminating the warm-up operation is acquired and the stack temperature is equal to or higher than the first threshold temperature, terminates the warm-up operation.SELECTED DRAWING: Figure 3
