Abstract:
Alkaline water electrolysis is one of the easiest methods for hydrogen production. Simplicity and usefulness are the two main features that characterize this method. The challenges for widespread use of water electrolysis are to reduce energy consumption, cost, durability and safety.
      In our investigation we obtain the results about energy efficiency system with the addition of ionic activators (i.a.) – Co(en)₃C_l3, Na₂MoO₄ and ZnC_l2, in 6 M KOH solution. The requirements per mass unit of hydrogen produced are reduced up to 15% just using simplified process of the in situ activation with d-metals. The most important result of this study is that obtained deposit exhibit long-term stability at elevated temperatures and high current densities, like industrial conditions.
