REFORMER, METHOD FOR PRODUCING HYDROGEN, APPARATUS FOR PRODUCING HYDROGEN, AND FUEL CELL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a reformer that efficiently reforms hydrocarbon compounds or hydrocarbon compounds having substituents containing heteroatoms with a catalyst, a method for producing hydrogen using the reformer, an apparatus for producing hydrogen, and a fuel cell system.SOLUTION: In one aspect of the present invention, a reformer 17 that reforms hydrocarbon compounds or hydrocarbon compounds having substituents containing heteroatoms comprises: a first catalyst 200 comprising a first carrier and a first noble-metal containing layer disposed on the first carrier; a second catalyst 100 comprising a second carrier and a second noble-metal containing layer disposed on the second carrier, wherein a thickness of the second noble-metal containing layer is larger than that of the first noble-metal containing layer.
