<P>PROBLEM TO BE SOLVED: To provide a selective oxidation air mixer of a small-sized and simple structure, since there is a problem that efficiencies of a hydrogen production apparatus and a fuel cell power generator are lowered when mixing performance of selective oxidation air is low. <P>SOLUTION: The hydrogen production apparatus 2 includes a reforming part 6 which forms a reformed gas containing hydrogen, a conversion part 7 which decreases carbon monoxide contained in the reformed gas and forms a converted gas, a mixer 1 which mixes the converted gas and selective oxidation air and forms a mixed gas, and a selective oxidation part 9 which removes carbon monoxide which remains in the mixed gas, wherein the mixer 1 is equipped with an inside tube 12 which supplies selective oxidation air, an outside tube 14 arranged on the outside of the inside tube 12 to which the converted gas is supplied, an opening through which selective oxidation air can pass on the same circumference of the inside tube 12 downstream of the supplying part of the converted gas, and an annular flow passage downstream of the opening. <P>COPYRIGHT: (C)2011,JPO&INPIT |
