PEM Electrolysis Stacks

h2agentur exclusively promotes PEM stacks from Plug Power (former Giner ELX), USA. These stacks are extremely durable, capable of being operated with differential pressure and very stable even under challenging conditions. The PEM stacks combine large production of H2 with high efficiency. High current densities allow for extreme compact design. The stacks are for serial production requirements.

PlugPower
  • Plug Power has been manufacturing PEM stacks over decades. Their PEM stacks have proven reliability and longevity in many applications worldwide, e.g. for over 20 years in life-saving systems of US Navy submarines. Also stacks for operation on International Space Station (ISS) were successfully designed.
  • Plug Power has gathered enormous knowledge and built up special expertise in developing PEM stacks for challenging conditions. Additionally to those mentioned track records show extreme low weight PEM stacks for airborne applications, extreme differential pressure of 350 bar and compact layout still enabling large hydrogen output achieved by high current densities.
  • Plug Power coats membranes using proprietary manufacturing process developed over many years.
