The quickCONNECTfixture (qCf) short stack test system is an indispensable tool for the research and development of PEM fuel cell stacks with up to 5 cells. It fulfills the highest requirements and enables easy testing of various internal components such as membranes, electrodes, CCMs, MEAs and GDLs. The qCf short stack test system with its stacking device enables direct regulation of the contact pressure on the short stack with up to 5 cells per 25 cm² active area via a pneumatic actuator, creating fully reproducible test conditions. Flow fields and MEA components can be easily exchanged and tested under different operating conditions.
