Complementary investigations of fuel cells with synchrotron x-rays and neutrons

  • Optimisation of water management in hydrogen PEM fuel cells
  • Liquid water necessary for membrane humidification, but gas flow is hindered
  • Optimal water distribution essential for high power output and longevity
  • Imaging of water distribution in an operating fuel cell in real time, while applying realistic power profiles and environmental conditions
  • Neutrons for investigations of a whole fuel cell, synchrotron x-rays for investigation of fine water accumulations in the porous gas diffusion layers.
