Patent ID: 7431898

Claim:
A chemical reaction apparatus comprising: a first substrate in which a reaction flow path, in which a fluid material containing hydrogen atoms as compositions flows, is formed, a reaction catalyst layer being formed in at least a portion of the reaction flow path, and a reaction of the reaction fluid on the reaction catalyst layer being caused in the reaction flow path to produce reaction products including hydrogen gas; and a second substrate including a heating element which comprises: a combustion flow path which is formed in the second substrate to correspond to the reaction flow path, and in which a combustion fluid flows, and a combustion catalyst layer formed in at least a portion of the combustion flow path, the combustion catalyst layer being different from the reaction catalyst layer, and the heating element heating the fluid material flowing in the reaction flow path by a reaction of the combustion fluid on the combustion catalyst layer to cause the reaction in the reaction flow path; wherein the first substrate and the second substrate are stacked.
