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. The PEM stacks link large production of H2 with high efficiency. Depending on the operating conditions efficiency can be > 90 % and one kilogram of hydrogen can be generated at 46 kWh. High current densities allow for extreme compact design.

Giner ELX
  • Giner has been manufacturing PEM stacks for over two decades. Their PEM stacks have proven reliability and longevity in many applications worldwide. This Giner has done especially in life-saving systems of US Navy submarines where 100 men rely heavily on the oxygen production. Giner even successfully designed stacks for use in space where again reliability is key.
  • Giner has gathered enormous knowledge and built up special expertise in developing PEM stacks for challenging conditions. Among others the track record show extreme low weight PEM stacks for use in space and airborne applications, very compact design combined with large hydrogen output achieved by high current densities of 3 A/cm2 and more, differential pressures of 350 bar. The knowledge gained is transferred to commercial product development.
  • To achieve outstanding performance Giner coats membranes in its own production using proprietary manufacturing process developed over many years.
