A method for producing by electrophoretic deposition multi-layer, polyfunctional, catalyst members for use in catalytic converters having a plurality of suitably porous and adherent catalyst support coatings of substantially uniform thickness, a plurality of non-identical catalytic agents imbued therein/on, and a flexible metal substrate, are disclosed. Such process involves maintaining electrical interaction between a metal substrate previously coated with catalyst-catalyst support material, the power source, and the electrodes disposed in the electrophoretic deposition ("EPD") cell containing a slurry of a second catalyst support material and a second catalyst composition non-identical to that found in the first catalytically-active layer.

[ What is claimed is:] [1.] A catalytically-active metal member comprising (1) a metal foil substrate having first and second primary surfaces and an edge surface, (2) a first catalyst and catalyst support material layer electrophoretically deposited on at least a portion of the first primary surface, said layer comprising a first catalyst and a first catalyst support material, and (3) at least one second catalyst and catalyst support material layer electrophoretically deposited on top of said first catalyst and catalyst support material layer, each of said second catalyst and catalyst support material layer comprising a second catalyst and a second catalyst support material, wherein each of said first and second catalyst and catalyst support material layers have a substantially uniform thickness.
