How is the end of lifetime of Enapter’s electrolysers defined?

Enapter has defined an end of life criteria for the electrochemical stack when an average cell voltage of 2.0V is exceeded (at nominal production rate, nominal operating temperature, and with fresh electrolyte solution). This means, roughly 15% of the stack degradation of a brand-new stack. Even after that point, the electrolyser will still be functional and can continue to produce hydrogen at a lower efficiency or production rate.
