Abstract

For katalytisk aktivering av en katode for alkalisk vannelektrolyse tilsettes et vannoppløselig platiname-tallsalt elektrolytten i elektrolysøren for å utskille platinametallet gal-vanisk på katoden mens elektrolysøren er i drift.For catalytic activation of a cathode for alkaline water electrolysis, a water-soluble platinum metal salt is added to the electrolyte in the electrolyzer to separate the platinum metal galvanically on the cathode while the electrolyzer is in operation.
