A study of the solubility in the ternary systems NaBH₄–NaOH–H₂O, KBH₄–KOH–H₂O, NaOH–NaBO₂–H₂O и KOH–KBO₂–H₂O is of special fundamental and practical interest. The first two systems are used as a fuel and as a hydrogen source in hydrogen power engineering that includes the low-temperature fuel cells; borohydrides are converted into metaborates. Hence, the last two systems represent the discharged by-product.

Depolarization of anode by sulfurous anhydride allows to reduce power inputs on hydrogen production in 1.5 times. The reason which prevents commercialization of this process is realization impossibility of industrial electrolysis current density because of SO₂ feeding diffusion limitation to anodic catalytic layer. Pressure influence on water electrolysis process with depolarization anode by sulfurous anhydride in solid polymer electrolyte electrolyzers is examined.
