FIELD: chemistry.
SUBSTANCE: invention relates to a method of preparing catalysts for electrolysis cells with a solid polymer electrolyte. A method is described for preparing a nanostructured catalyst for electrolysis of water, which involves dissolving initial compounds which include iridium or iridium combined with ruthenium, as well as a modifying additive, deposition of initial compounds, separation and drying the said compounds and thermal treatment of the compounds, where when dissolving the initial compounds, a disintegrant is added in amount of not more than 10 times more than the mass of initial compounds.
EFFECT: increased active specific working area of the catalyst.
