LONG-TERM STABILITY OF THE IN-SITU ELECTROPHORETIC ACTIVATION OF TECHNICAL CATHODES

The long-term stability of a new electrophoretic insitu activation of cathodes was tested under tough industrial conditions. It was seen in these tests that this activation, which employs electrocatalysts witho ut expensive noble metals, can be applied, essentially without any dis ruption of hydrogen production and without any downtime of the electro lyzers. This activation proved to be stable in its effect and insensit ive to catalyst poisoning over a number of years.
