PEM Electrolysis Stacks

h2agentur exclusively promotes in Germany and Denmark PEM stacks from Giner Inc., USA. Giner is the oldest company in PEM electrolysis and market leader. The stacks are extremely durable, capable of being operated with differential pressure and very stable even under challenging conditions. They combine high H2 production with high efficiency. The efficiency can be 85 % depending on the operating conditions, one kilogram of hydrogen can be generated by 46 kWh.
