Cell Compression Unit

Description:

The compression force applied to the fuel cell core has a drastic influence on performances: it modifies the gas permeation, water management and electrical contact between interfaces. Thanks to the Cell Compression Unit (CCU), you will now be able to precisely measure the influence of compression over MEA and GDL. The Cell Compression Unit is composed of two parts: a high accuracy, programmable electric press having a specific cradle to receive the single fuel cell. The frame is equipped with gas and electric load connections to test stand, a specific fuel cell with a moving part transferring the press compressive force to the active surface of the Membrane-Electrode Assembly.

The cell design achieves gas tightness and compressive force with two separate actions. The force applied by the CCU piston is only transmitted to the active surface for perfect reproducibility and accuracy. Test conditions are independent from gaskets type and samples thickness. Place your components in the single-cell hardware, the CCU will command and control the exact pressure setpoint with unparalleled accuracy. The CCU is a fully autonomous, self-regulated unit, equipped with a force sensor, displacement sensor and a graphical touch screen interface.

Key features:

  • Delivers perfect reproducibility of samples testing conditions independently from samples thickness, softness or material used
  • Determination of optimal contact force on CCM
  • Simultaneously measures the force applied on sample and thickness variation of sample
  • Operates at constant force or constant thickness
  • Includes cell heating and temperature control up to 240C
  • Real time graphs display
  • Ethernet connection for remote control
