Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel cell ships face significant damage risks due to the potential explosion of storage batteries, necessitating measures to minimize such damage.
Innovation Solution
The fuel cell ship is designed with comprehensive safety measures, including gas and fire detectors, shutoff valves, and ventilation systems to detect and prevent the accumulation of combustible gases, ensuring immediate shutdown of fuel gas supply in case of leaks or fires, thereby minimizing explosion risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a storage battery is installed in the fuel cell ship, then the auxiliary power source function is improved, but the explosion damage risk increases
Solution Approach 1:
The ship is divided into multiple compartments with the storage battery isolated in a dedicated battery compartment separated from the fuel cell compartment and other critical areas. This spatial segmentation prevents explosion propagation and limits damage scope while maintaining auxiliary power functionality.
Solution Approach 2:
Gas detectors and control systems are introduced as intermediary components between the storage battery and the fuel cell system. These detectors continuously monitor for gas leaks and automatically trigger shutoff valves to close fuel supply, creating a protective intermediary layer that prevents direct harmful interaction between battery explosions and fuel systems.
2Reliability
If gas detectors and shutoff valves are installed, then the safety response capability is improved, but the device complexity increases
Solution Approach 1:
The control system is configured to automatically respond to gas detector signals without requiring manual intervention. When the gas detector detects combustible gas, the system self-activates the shutoff valves to close fuel supply, creating a self-service safety mechanism that improves reliability while minimizing operational complexity.
Solution Approach 2:
Multiple safety functions (gas detection, automatic shutoff control, ventilation activation) are merged into an integrated safety control system. This consolidation reduces the number of independent control mechanisms needed while maintaining comprehensive safety coverage, thereby improving reliability without proportionally increasing device complexity.

AI summary
[Problem] To provide a fuel cell ship capable of minimizing damage when a storage battery explodes for some reason. [Solution] A fuel cell ship includes a storage battery compartment installed with a storage battery that supplies, to a propulsion device, electric power different from electric power by a fuel cell. The storage battery compartment is provided between a deck and a ship bottom portion of a hull.
