Solution Overview

Problem

Current control methods for fuel cell systems are limited in their ability to effectively manage various types of fuel cell systems, particularly in redesigning control modules, and have not yet adequately addressed associated problems.

Innovation Solution

A distributed control module for fuel cell systems is introduced, comprising a master controller and multiple slave controllers connected to hydrogen tanks, allowing for management of valves and hydrogen tanks based on temperature or pressure, with information transmission between controllers to facilitate efficient system management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a centralized control module is used for fuel cell systems, then the system structure is simple, but the system lacks adaptability and fault tolerance when managing various types of fuel cell systems

Engineering Contradiction:
Improveadaptability to various fuel cell systemsVSAvoidcontrol module structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control module is divided into a master controller and multiple slave controllers. Each slave controller independently manages specific fuel cell modules or hydrogen tanks, while the master controller coordinates overall system operation. This segmentation enables the system to adapt to various fuel cell configurations without redesigning the entire control architecture.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the control module is redesigned to improve adaptability, then versatility increases, but development time and cost increase

Engineering Contradiction:
Improvecontrol module versatilityVSAvoiddevelopment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The slave controllers are designed as universal modules that can manage different types of fuel cell stacks and hydrogen storage systems through standardized interfaces. This multi-functionality allows a single control module design to serve multiple fuel cell system configurations, eliminating the need for time-consuming redesigns for each application.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of repair

If individual control modules are made replaceable, then ease of repair improves, but system complexity increases

Engineering Contradiction:
Improvemodule replaceabilityVSAvoidsystem architecture
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The control system is segmented into independent master and slave controller modules with standardized communication interfaces. This modular architecture allows individual slave controllers to be replaced or upgraded without affecting other parts of the system, significantly improving ease of repair while maintaining manageable system complexity through clear module boundaries.

Inventive Principle:
Principle #1Segmentation
