ABSTRACT:
The invention relates to an electrocatalyst capable of being used, in particular, in anodes of fuel cells with acid electrolyte, and to a process for the manufacture of this electrocatalyst. The electrocatalyst contains at least one ternary metal compound which is composed of one metal of the iron group of the periodic table of elements, i.e. iron, cobalt or nickel, and two different elements of the phosphorus, arsenic, antimony, bismuth, sulfur, selenium and tellurium group, and has semiconducting characteristics. Examples of such ternary metal compounds serving as electrocatalysts are FePS, CoPS and CoAsS. The new electrocatalysts show a high catalytic effect and are insensitive to catalyst poisons.
