Abstract
A barrier film which has uniform thickness and excellent adhesiveness to the base material and superbly functions to protect a platinum film can be formed on the inner wall surface of a moisture-generating reactor at ease and at a low cost. The moisture-generating reactor in which hydrogen and oxygen are reacted to generate moisture without high temperature combustion is made of an alloy containing aluminum. A principally aluminum oxide (AlO)-composed barrier film is formed by applying an aluminum selective oxidation treatment on the inner wall surface of the moisture-generating reactor, and thereafter a platinum film is stacked on and stuck to the barrier film so that a platinum coating catalyst layer is formed.
