Abstract
A method for controlling a fuel cell system is provided. The method includes upon start of a fuel cell stack, obtaining a flow rate of air supplied into a cathode after an air regulator for regulating the air supplied into the cathode is opened. A sealing state of the fuel cell stack is then determined based on the obtained flow rate of the air.
Claims12
A method for controlling a fuel cell system, comprising:
- upon start of a fuel cell stack, obtaining, by a controller, a flow rate of air supplied into a cathode after an air regulator configured to regulate the air supplied into the cathode is opened;
- and
- determining, by the controller, a sealing state of the fuel cell stack, based on the obtained flow rate of the air,
- wherein the fuel cell stack is determined to be in a normal sealing state when the flow rate of the air is greater than or equal to a preset threshold value and in an abnormal sealing state when the flow rate of the air is less than the preset threshold value.

A method for controlling a fuel cell system, comprising:
- upon start of a furl cell stack, obtaining, by a controller, a flow rate of air supplied into a cathode after an air regulator configured to regulate the air supplied into the cathode is opened;
- determining, by the controller, a sealing state of the fuel cell stack, based on the obtained flowrate of the air;
- and
- performing, by the controller, safety control to temporarily connect a resistor to the fuel cell stack to reduce high electric potential generated in the fuel cell stack, in response to determining that the fuel cell stack is in an abnormal sealing state.
1 more element
A fuel cell system, comprising:
- at least one processor;
- an air flow-rate acquisition device connected to the at least one processor and configured to obtain a flow rate of air supplied into a cathode;
- and
- a memory connected to the at least one processor and configured to store a plurality of instructions,
- wherein the instructions, when executed, cause the processor to:
- upon start of a fuel cell stack, operate the air flow-rate acquisition device to obtain the flow rate of the air supplied into the cathode after an air regulator configured to regulate the air supplied into the cathode is opened;
- and
- determine a sealing state of the fuel cell stack, based on the obtained flow rate of the air, and
- wherein the fuel cell stack is determined to be in a normal sealing state when the flow rate of the air is greater than or equal to a preset threshold value and in an abnormal sealing state when the flow rate of the air is less than the preset threshold value.
