INTEGRATED SYSTEM WITH
ADVANCED CONTROL FOR THERMAL MANAGEMENT
AND ANTI-FREEZE MODULE

What are the main functions of the anti-freeze module?

In extreme cold weather, down to -40°C (-40°F), unattended cold start might not be reliable. In that case a more elaborated approach is used. The core idea is to prevent the formation of ice by using an antifreeze. Although this is a more complex procedure, it is expected to enable a cold start of fuel cell systems at extreme cold conditions.

What are the development goals for the integrated thermal management system?

The objectives are to optimize the fuel cell cooling circuit in terms of efficiency and quality of control. Conventional unattended cold start down to moderate freezing conditions is supported by the minimization of heat capacity. For extreme cold ambient conditions a new cold start procedure, which utilizes an antifreeze to prevent formation of ice inside the fuel cell, will be developed. The new concept will enable cold start down to -40°C (-40°F) and thus significantly increase the reliability of fuel cell vehicles.

Alongside the cost-reduction of the thermal management components, another key target is the reduction of their weight and volume since installation space in fuel cell vehicles is very limited.
