Integrated Fuel Cell Control System Reducing Controller Noise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fuel cell control systems have separate fuel processing systems (FPS) and fuel control units (FCU), leading to noise between controllers, increased costs, complex packaging, reduced control efficiency, and increased wire complexity.
Innovation Solution
An integrated fuel cell control system where the FCU directly operates sensors, valves, and heaters, simplifying the package configuration and reducing wire complexity by integrating the FPS with the FCU.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the fuel cell control system uses separate FPS and FCU controllers, then each controller can independently control its functions, but noise between controllers increases and control efficiency decreases
Solution Approach 1:
The patent merges the FPS and FCU controllers into a single integrated controller. The FCU now directly controls hydrogen supply valves, pressure sensors, and other fuel processing components without requiring separate FPS controller mediation. This integration eliminates inter-controller communication noise while maintaining all necessary control functions through direct control pathways.
2Adaptability or versatility
If separate FPS and FCU controllers are used, then specialized control functions are available, but system costs increase and packaging becomes complex
Solution Approach 1:
The FCU is designed to perform multiple functions previously distributed across separate controllers. It now handles hydrogen supply control, pressure regulation, valve control, and sensor monitoring directly. This multi-functional design eliminates the need for separate FPS controller hardware, reducing packaging complexity while preserving all specialized control capabilities within the FCU.
3Adaptability or versatility
If separate FPS and FCU controllers are used, then control functions are distributed, but wire complexity increases and control efficiency decreases
Solution Approach 1:
The patent extracts the FPS controller from the system and integrates its control functions directly into the FCU. This eliminates the need for communication wires and data buses between separate FPS and FCU controllers. The FCU now directly interfaces with all fuel processing components through simplified wiring, reducing wire complexity while maintaining distributed control functionality within the single controller architecture.

AI summary
An integrated fuel cell control system is provided. The integrated fuel cell control system includes at least one sensor, at least one hydrogen on/off valve, and a fuel control unit (FCU). The FCU is configured to directly operate the at least one sensor and the at least one hydrogen on/off valve in real time and to determine a supply pressure of hydrogen supplied to a fuel cell. Thereby, noise between controllers may be removed and costs may be reduced.
