FIELD: electricity.
SUBSTANCE: invention is referred to catalyst layer for fuel element with solid polymer electrolyte and to method of catalyst layer production for fuel element with solid polymer electrolyte and to fuel element with solid polymer electrolyte. According to invention, catalyst layer for fuel element with solid polymer electrolyte including membrane from solid polymer electrolyte, electrodes and catalyst layers, each located between membrane from solid polymer electrolyte and associated electrode, is comprised of catalyst with tree-pattern. Catalyst with tree-pattern is produced by vacuum spraying similar to reactive electron deposition, reactive electron-beam deposition or ion deposition.
EFFECT: improved catalyst activity; better catalyst rate of use and characteristics of substance transfer in catalyst layer.
