qCf - Our revolutionary test cell system for professional characterisation of fuel cells

The quickCONNECTfixture with an active fuel cell area of 25 cm² has been an established part of our product range since 2006. The cellFixture's excellent characteristics and patented design offer enormous advantages when characterising internal components for fuel cells and electrolysis. Various models are available for a range of applications. The quickCONNECTfixture can, for example, be supplied as an electrically heated or a liquid cooled model.

Flow field plates are key components in fuel cells. There is a very large, diverse range of configuration options, ranging from straight, parallel channels to a serpentine design. Graphite is used as the base material for flow field plates in fuel cells.

For electrolysis applications, both the configuration and the flow field plate base material are key. To avoid damage to the graphite on the anode during PEM electrolysis of water we use flow field plates made from titanium. Gold or platinum coatings can also be supplied.

For electrolysis applications in the alkaline range we use nickel flow field plates for the anode and cathode.

Continuously modifiable contact pressure ensures full reproducibility of test conditions
The thickness of the fuel cell components is not an issue thanks to a self-adjusting piston and a special sealing design
No time-consuming connection and disconnection of hoses or cables required to change the cellFixture
The cellFixture can be clamped quickly and easily with no tools required. The same applies to precise changing over of the internal cell components
Maximum power density thanks to control of the optimum contact pressure on the active cell area
Developed for heavy use use in quality control and lab environments
