METHOD FOR FORMING PLATINUM COATING CATALYST LAYER IN REACTION FURNACE FOR GENERATING WATER GAS

摘要

AbstractA 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 ata 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 (AI203)-composedbarrier 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.
