THIN LAYER CATALYST TO ADHERE TO A METALLIC SUBSTRATE AND METHOD OF FORMING THE SAME

摘要

A method of forming a catalyst coating on a metallic surface is disclosed. The method comprises: mixing non-dispersible catalyst particles of between 1 and 100 microm in size with water and an oxide as a dispersible solid to form a washcoat; adjusting the pH of the washcoat to produce a predetermine viscosity; coating the washcoat onto a metallic surface; and drying and calcining the coating. A catalyst coating for application to a metal surface and a steam reformer and a fuel cell with catalyst coatings applied by the above method are also disclosed.
