で、コンパクト化が図れる。When a gas containing several percent to several percent of CO is introduced into the shift reaction section through the inlet, it passes between the shift catalysts, whereby CO is converted by the exothermic reaction. Since the heat generated by the heat generation is removed by the cooling medium flowing through the preheating section, the gas temperature at the outlet of the shift reaction section is lowered and the reformed gas having a CO concentration of 1% or less can be taken out. Since the plate type has a large heat transfer area per unit volume, it can be made compact.
