TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If a cooling system for fuel cell stacks is integrated into existing vehicle systems, then the cooling function is achieved, but integration costs increase and maintenance ease deteriorates
Why choose this principle:
The cooling system is divided into modular components: a first cooling module specifically for the fuel cell stack and a second cooling module for the vehicle's general cooling needs. This segmentation allows independent integration and maintenance of each module, reducing overall system complexity while ensuring reliable cooling for the fuel cell stack.
Principle concept:
If a cooling system is adapted to existing vehicle systems, then integration is achieved, but maintenance ease deteriorates
Why choose this principle:
By segmenting the cooling system into distinct first and second cooling modules, each with its own connections and components, the system becomes more adaptable to different vehicle configurations while maintaining ease of maintenance. Each module can be serviced independently without affecting the other.

Abstract
The invention relates to a cooling system ( 10 ) for fuel cell stacks ( 22, 26 ), comprising a first cooling module ( 14 ) and a second cooling module ( 18 ). The first cooling module ( 14 ) comprises a fuel cell stack ( 22, 26 ), a supply line connection ( 30, 34 ) for connecting a supply line ( 38, 42 ) for supplying coolant to the fuel cell stack ( 22, 26 ), a discharge line connection ( 46, 50 ) for connecting a discharge line ( 54, 58 ) for discharging coolant from the fuel cell stack ( 22, 26 ), and a venting line connection ( 94, 98 ) for connecting a venting line ( 102, 106 ).
