Abstract
A method of disposing catalyst in a reformer is disclosed. The method of disposing catalyst comprises the steps of providing a silicon-based substrate with a predetermined pattern thereon; providing a cover with an inlet hole and an outlet hole therein; bonding the silicon-based substrate with the cover; and disposing a catalyst solution on a wall of the predetermined pattern by centrifuging in a predetermined speed for a predetermined time so as to obtain a catalyst layer with a gradient-thickness on the wall.
