[0036] According to one embodiment, the fuel cell system device may include a master controller 110 and at least one slave controller 121, 122.

[0037] The fuel cell system device may include at least a portion of the control device for the fuel cell system described later. The fuel cell system device may include a distributed module for a non-vehicle fuel cell system. The fuel cell system device may include a non-vehicle fuel cell system or may be applied to / used in a non-vehicle fuel cell system.

[0038] A fuel cell system device may include a fuel cell system or at least a part of a fuel cell. A fuel cell system device may include at least a part of an electrical circuit, an electronic circuit, a communication circuit, a processor, a semiconductor, a memory, a data transceiver, and a valve.

[0039] A fuel cell system device may include at least some of all the components used to illustrate the invention in this invention, or may be capable of performing at least some of all the operations / functions.

[0040] The slave controllers 121 and 122 can be connected to the master controller 110.

[0041] According to one embodiment, slave controllers 121 and 122 can be connected to valves 131 and 132 which are connected to a hydrogen tank.

[0042] According to one embodiment, the slave controller may include a first slave controller 121 and a second slave controller / nth slave controller 122, where n is a natural number greater than or equal to 2.

[0043] The first slave controller 121 is connected to the first hydrogen tank valve 131, and the second slave controller / nth slave controller 122 may be connected to the second hydrogen tank valve / nth hydrogen tank valve 132, respectively.

[0044] According to one embodiment, the fuel cell system device may further include a first hydrogen tank (not shown) connected to a first hydrogen tank valve 131, and a second hydrogen tank / nth hydrogen tank (not shown) connected to a second hydrogen tank valve / nth hydrogen tank valve 132.

[0046] According to one embodiment, the slave controllers 121 and 122 may include a slave coupling section that connects to the master controller 110.

[0048] According to one embodiment, the fuel cell system device may further include a fuel cell controller (not shown) that transmits control commands to hydrogen tank valves 131 and 132 to a master controller 110.

[0049] Fuel cell systems can be designed and configured in a distributed type topology.

[0050] Fuel cell systems are divided into master and slave controllers, and their modular design allows for easy expansion.

[0051] In the event of a component failure in a fuel cell system, only the faulty part needs to be replaced.

[0052] The fuel cell system can minimize the number of elements that need to be modified to the extent that it can even replace a centralized HMU with three hydrogen tanks.

[0053] The fuel cell system can be designed to avoid changes to the hardware (HW) and software (SW) of other components (BoP: Balance of Plant).

[0054] Figure 2 is a diagram showing a fuel cell system according to one embodiment.

[0055] Fuel cell systems offer advantages over existing centralized PCB (Printed Circuit Board) systems, including simpler wiring, reduced artwork and time requirements. Furthermore, fuel cell systems simplify and clarify fail-safe algorithms and diagnostic systems for problem identification.

[0056] The fuel cell system equipment has been designed with component service (AS) characteristics in mind, which can reduce replacement costs and time when problems are discovered. It can be standardized to a single specification, allowing for delivery and management of slave controllers and assemblies.

[0057] Fuel cell systems may be classified as high-risk components when certified as non-vehicle products, but adding redundancy to a master-slave structure can potentially provide more options.

[0058] The fuel cell system can resolve unexpected situations on its own. If the fuel cell system or at least a part of the fuel cell is not functioning properly, the fuel cell system can detect this and control it to return to normal operation or shut off the problematic part.

[0059] The master and slave controllers of a fuel cell system do not necessarily need to be wired together. The master controller may include a master HMU (hydrogen storage system management unit), and the slave controller may include a slave HMU.

[0060] The master and slave controllers may be directly connected by a connector. Alternatively, the master and slave controllers may be connected by a board-to-board (B to B) connector and housed in a single housing.

[0061] According to one embodiment, the master controller 210 may include a master coupling section that connects to slave controllers 221, 222, 223, and 224.

HTVn, respectively. The hydrogen tank valve coupling section may include a connector or a pin port.

[0064] Figure 3 is a diagram showing the configuration of a fuel cell system according to one embodiment.

[0065] The fuel cell system device may further include a fuel cell controller (FCU) 301 that transmits control commands to the hydrogen tank valve HTV1 to the master controller 310.

[0066] The fuel cell controller 301 may include a fuel cell control coupling section that connects to the master controller 310. The fuel cell control coupling section may include a connector or pin port, and may include a 40-pin connector (pin conn.).

[0067] The fuel cell controller 301 may include an MCU, a CAN driver, an interface, etc.

[0068] The master controller 310 may include a master coupling unit 311 that connects to a slave controller 320 or a fuel cell controller 301. The master coupling unit 311 may include a 40-pin connector.

[0069] The master connection unit 311 can be connected to up to approximately 6 slave controllers or slave modules, and in practice, the number of pins may be increased further.

[0070] Even if the size of the hydrogen tank or the valve specifications of the hydrogen tank valve (HTV) change, only the slave controller needs to be changed, and the master controller can remain as is.

[0071] The slave controller 320 may include a slave coupling section for connecting to the master controller 310. The slave coupling section may include a 6-pin connector. The slave controller 320 may also include a hydrogen tank valve coupling section for connecting to the hydrogen tank valve HTV1.

[0073] The MCU321 can be added to a slave controller at a lower specification for more precise HMU control and bidirectional checking.

[0074] The signals / control signals generated by the MCU of the fuel cell controller 301 can be transmitted to the master controller 310 via the CAN driver, interface, and connector.

[0075] The valve open / close commands transmitted by the fuel cell controller 301 can be transmitted to the MCU of the master controller 310 via the connector (fuel cell control connection section and master connection section). The MCU of the master controller 310 can transmit PWM (Pulse Width Modulation) to the driver of the master controller 310 on a duty cycle or perform control using PWM. The driver of the master controller 310 can transmit the signal output from the driver to the FET of the slave controller 320 via the connector (master connection section and slave connection section). The FET of the slave controller 320 can amplify the signal output from the driver that it receives.

[0076] The slave controller 320 can receive information / signals regarding pressure or temperature to the hydrogen tank / hydrogen tank valve from the hydrogen tank valve HTV1 via a connector (hydrogen tank valve connection). The slave controller 320 can receive / transmit or sense current from its FET to its sensor / sensing unit, and transmit / transmit the received / transmitted or sensed information / signals to the MCU of the master controller 310 via a connector (master connection and slave connection).

[0077] Figure 4 is a diagram showing the replacement of individual modules in a fuel cell system according to one embodiment.

[0078] The fuel cell system device has several components that are prone to problems, such as the MCU401, FET402, and hydrogen tank valve403. When a problem occurs, these modules can be removed and replaced individually.

[0079] From the perspective of the fuel cell controller (FCU), if the FET 402 or hydrogen tank valve 403 can be replaced individually in the event of a problem, the diagnostic and fail-safe phases will be simplified, and the execution of decision-making logic may be further accelerated.

[0080] When developing power packs with diverse specifications for fuel cell systems, the system can be easily configured by adding slave HMUs to the remaining pins to match the number of hydrogen tanks to be used, and only modifying the software of the master HMU.
