qCf Liquid Cooling High Amp - Our system for professional characterisation of fuel cells for high current densities and direct flow field cooling

This version of our quickCONNECT test units offers significant improvements in the areas of high current densities and temperature management. The qCF LC High Amp has been developed for operation at current densities of up to 5A/cm². Reducing heat build-up, which can become a critical problem, was a major design challenge. We were able to solve it in partnership with the Fraunhofer ISE. The cooling sections were relocated so that they were in direct contact with the flow field plates, allowing the generated heat to be efficiently dissipated from the cell (DT < 1 K).

Active fuel cell area: 12 cm²
Operation at extremely high current density: Up to 5 A/cm²
Liquid heating/ cooling (optional accessory: HUBER ministat)
Cooling areas in direct contact with the flow field plate
Ideal for testing high energy density applications (e.g. automotive)
