Reaction substrate for a reformer of a fuel cell system, manufacturing method thereof, and reformer including the reaction substrate

摘要

The present invention relates inter alia to a reaction substrate for a reformer of a fuel cell system as well as to a manufacturing method thereof. The inventive reaction substrate comprises a substrate body having a channel adapted to permit a flow of fuel; a catalyst supporting layer formed on the surface of the channel; and a catalyst layer formed on the catalyst supporting layer. The substrate body is made of materials comprising aluminium and the catalyst supporting layer is formed by performing an oxidation treatment of the surface of the channel.
