Abstract
Disclosed are an apparatus for controlling a valve of a fuel cell system, and a method thereof. The apparatus includes a valve configured to discharge, through an exhaust of the fuel cell system, gas inside a cathode of a fuel cell stack of the fuel cell system. The apparatus may, for example, determine, based on a pressure measured inside the fuel cell stack, an opening time of the valve and an opening time duration of the valve, and open, while the fuel cell system is in a shutdown state, the valve at the opening time and keep the valve open for the opening time duration.
Claims20
An apparatus of a fuel cell system, the apparatus comprising:
- a valve configured to discharge, through an exhaust of the fuel cell system, gas inside a cathode of a fuel cell stack of the fuel cell system;
- a processor;
- and
- a memory storing at least one instruction that is configured, when executed by the processor communicating with the memory, to cause the apparatus to:
- determine, based on a pressure measured inside the fuel cell stack, an opening time of the valve and an opening time duration of the valve;
- and
- open, while the fuel cell system is in a shutdown state, the valve at the opening time and keep the valve open for the opening time duration.
A method performed by a fuel cell system, the method comprising:
- determining, by a processor of the fuel cell system and based on a pressure measured inside a fuel cell stack of the fuel cell system, an opening time and an opening time duration of a valve of the fuel cell system;
- and
- opening, while the fuel cell system is in a shutdown state, the valve at the opening time to discharge gas inside a cathode of the fuel cell stack and keeping the valve open for the opening time duration.
A vehicle comprising:
- a fuel cell stack configured to produce electrical energy, wherein the fuel cell stack comprises a cathode and an exhaust;
- an air compressor configured to supply air to the cathode of the fuel cell stack;
- a valve configured to discharge, through the exhaust, gas inside the cathode;
- and
- a processor circuit configured to:
- determine, based on a pressure measured inside the fuel cell stack, an opening time of the valve and an opening time duration of the valve;
- and
- open, while the fuel cell system is in a shutdown state, the valve at the opening time and keep the valve open for the opening time duration.
