Patent ID: 7896933

Claim:
A hydrogen supplying apparatus comprising a reactor, which comprises a hydrogen separation membrane that permeates hydrogen atoms, supported on a first metallic member and a catalyst supported on a second metallic member, wherein the first metallic member and the hydrogen separation membrane are bonded by means of a first reaction layer formed in the interface of the first metallic member and the hydrogen separation membrane, and the hydrogen separation membrane and the second metallic member are bonded by means of a second reaction layer formed in the interface of the hydrogen separation membrane and the second metallic member, wherein the second metallic member and the hydrogen separation membrane are bonded by friction stir welding, wherein the first metallic member and the hydrogen separation membrane are bonded by friction stir welding, and wherein a weld position between the second metallic member and the hydrogen separation membrane is shifted in a direction along the interface of the first metallic member and the second metallic member, with respect to a weld position between the first metallic member and the hydrogen separation membrane.
