qCf short stack

qCf short stack: Our system for the professional characterization of fuel cell short stacks with liquid cooling from 2 to 5 cells.
It enables easy testing of various internal components such as membranes, electrodes, CCMs, MEAs and GDLs. The stacking device enables direct regulation of the contact pressure on the short stack via a pneumatic actuator, which creates fully reproducible test conditions. Flow fields and MEA components can be easily exchanged and tested under different parameters.
