Title:
FUEL REFORMER FOR FUEL CELL
Document Type and Number:
Japanese Patent JP3675946
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel reformer for a fuel cell capable of simultaneously reducing the collapse of a granular reforming catalyst and the carbon deposition on the granular reforming catalyst.
SOLUTION: This fuel reformer 1 for a fuel cell is designed to use a catalyst layer 2 having a partial catalyst layer 21, a partial catalyst layer 22 and a partial catalyst layer 23 as a catalyst layer as opposed to a conventional example. The partial catalyst layer 21 is the one, filled with a noble metallic granular reforming catalyst 3 and arranged at a site for making a raw material gas 9a of the catalyst layer 2 flow thereinto. The partial catalyst layer 23 is the one, filled with the noble metallic granular reforming catalyst 3 and arranged at a site for discharging the reformed gas 9b of the catalyst layer 2 therefrom. The partial catalyst layer 22 is the one, filled with a nickel-based granular reforming catalyst 4, sandwiched and arranged between the partial catalyst layers 21 and 23.
