Problems solved by technology

However, it is necessary to remove the adhesive from the Pd alloy film located in the pores of the support, which brings about a problem that the manufacturing process is complicated.
In addition, since the reformer is used under high temperature and high pressure, it is difficult to avoid the deterioration of the adhesive, and the durability of the filter cannot be fully exerted.
[0010] Further, in order to maintain the desired strength of the support body, the size of the opening diameter of the hole that the support body has is limited, and furthermore, the expansion of the area of ​​the effective Pd alloy film for hydrogen penetration is also limited, which brings about the improvement of hydrogen gas. barriers to efficiency

Embodiment 1

[0100] Fabrication of filters for hydrogen production

[0101] Prepare a SUS430 material with a thickness of 50 μm as a base material, and apply a photosensitive resist material (OFPR manufactured by Tokyo Ohka Industry Co., Ltd.) (film thickness 7 μm (when dry)) to both sides of the SUS430 material by dipping method, Next, a photomask in which a plurality of circular openings having an opening size (opening diameter) of 120 μm is arranged at a pitch of 200 μm is placed on the above-mentioned resist coating film, and the resist coating is applied through the photomask. The film was exposed and developed using sodium bicarbonate solution. In this way, a resist pattern having a circular opening with an opening size (opening diameter) of 120 μm was formed on both surfaces of the SUS430 material. In addition, the centers of the openings of the resist patterns formed on the respective surfaces were made uniform by the SUS430 material.

[0102] Then, using the above resist patte...

Abstract

The invention relates to a method for producing hydrogen production filter, comprising: in a through hole closing process, a metal plate is attached to one surface of a conductive base member having a plurality of through holes by the use of a magnet, in a copper plating process, a copper plating layer is formed on the conductive base member and the metal plate exposed within the through holes, from the side of the conductive base member where the metal plate is not attached, thereby to fill up the through holes, in a film forming process, a Pd alloy film is formed by plating on the surface of the conductive base member after removal of the metal plate, and in a removal process, the copper plating layer is removed by selective etching, thereby to produce a hydrogen production filter that is used in a reformer of a fuel cell so as to be capable of stably producing high purity hydrogen gas.
