A method of forming a hydrogen transport membrane to separate hydrogen from a hydrogen containing feed in which a porous ceramic support is formed to support a dense layer of palladium or an alloy of palladium serving as a hydrogen transport material. Isolated deposits of palladium, a palladium alloy or a component of such alloy are produced on a surface of the porous ceramic support that bridge pores within the porous ceramic support without penetrating the pores and without bridging regions of the surface defined between the pores. The isolated deposits of the metal are produced by an electroless plating process that involves contacting the porous ceramic support with a precipitating agent so that the precipitating agent fills the pores but does not seep out of the pores onto the regions of the surfaces defined between the pores. The surface is then contacted with a salt solution containing a salt of the metal so that said metal precipitates and produces the isolated deposits of the metal.
