<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a hydrogen producing filter which is used in a reformer for a fuel cell so that high-purity hydrogen gas can be produced stably. <P>SOLUTION: This hydrogen producing filter is manufactured by attaching a metallic plate onto one side of an electrically conductive base material having several through-holes by using a magnet at a through-hole plugging step, burying the through-holes by forming a copperized layer on the metallic plate-unattached side of the base material and the metallic plate exposed through the through-holes at a copperizing step, forming a Pd alloy film on the metallic plate-removed side of the base material by plating at a film forming step and removing the copperized layer by selective etching at a removal step. <P>COPYRIGHT: (C)2004,JPO |
