PROBLEM TO BE SOLVED: To provide an oxidation catalyst coat structure having the function of making the amount of reaction uniform along the direction of the gas stream in the oxidation combustion of hydrogen in an integrated catalyst/heat exchanger so as to heighten the efficiency of the heat exchanger. SOLUTION: By coating the heating surface with an oxidation catalyst comprising a catalyst component and a catalyst support component, wherein the amount of the catalyst component has a distribution in the direction of the flow of a feedstock gas to establish the uniformity of the amount of reaction along the flow of the gas and uniform heat supply, the thermal efficiency of the heat exchanger can be increased, and the apparatus is freed from troubles such as damage. |
