qCf 12 High Amp

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)

The latest version of our quickCONNECT test cells comes with siginificant improvements in temperature management. The qCF LC high amp was designed for the operation at high current densities where heat generation becomes a critical issue. In cooperation with Fraunhofer ISE, the liquid cooling layers where shifted closer to the flow fields and ended in direct contact to the graphite flow field plates to extract generated heat more efficiently from the cellFixture. A temperature difference between cathode gas outlet and cooling liquid of less than 1 K is realised at 5 A/cm² and 80 °C. All advantages of the quickCONNECT principle like adjustable contact pressure on the active area, independence of thickness of specimens due to a self adjusting monopolar piston and the toolless assembly were retained to assure easy handling and highest reproducibility of results.
