PEM Electrolysis Stacks

h2agentur exclusively promotes PEM stacks from Giner ELX, USA. These stacks are extremely durable, capable of being operated with differential pressure and very stable even under challenging conditions. They link high H2 production to high efficiency. Depending on the operating conditions the efficiency can be 85 %, one kilogram of hydrogen can be generated by 46 kWh.

Giner ELX
  • Giner PEM stacks have been manufactured and have been proven over many years in permanent use. Especially as life-saving systems for oxygen production in Navy submarines. Giner ELX has also successfully designed stacks for use on the ISS in space. Each one of them confirms the trust placed in Giner.
  • Giner has built up a very special knowledge over decades and was able to develop stacks as special developments for operation in weightlessness as well as for extreme pressures of 350 bar. The knowledge gained also benefits Giner ELX's commercial products.
  • Giner ELX coats the membranes itself in its own production halls using its own manufacturing process developed over many years. Therefore they are extremely resilient, highly efficient and very stable over the long term.
