Abstract
A reformer is disposed in the flow path of a reactant fluid. The reformer includes an electrically heatable heater unit of honeycomb structure, in the upstream of the flow path of a reactant fluid, and a catalyst unit of honeycomb structure capable of generating hydrogen from a reactant fluid containing an organic compound or carbon monoxide, by catalysis, in the downstream of the above heater unit. The heater unit and catalyst unit satisfy the following relationship: Cell density of the heater unit≦Cell density of the catalyst unit. The reformer improve efficiency for production of hydrogen and reduce CO as the by-product.
