Abstract

The present invention relates to a fuel processing device comprising a device body; a fuel reforming part disposed at the center of the device body; a heating part disposed at the upper side of the device body so as to heat the fuel reforming part; a CO denaturation part connected to the fuel reforming part, and disposed at the lower side of the device body; and a preferential oxidation (PROX) reaction part connected to the CO denaturation part, and disposed at the upper side of the device body. The present invention improves heat transfer and cooling efficiency through optimal arrangement, stably performs a reforming reaction and a CO removal reaction, and is advantageous in miniaturizing the device.

Description

technical field [0001] The present invention relates to a fuel processing apparatus, and more particularly, to a fuel processing apparatus that can improve heat transfer and cooling efficiency by an optimal arrangement, stably perform a reforming reaction and a CO removal reaction, and contribute to miniaturization of the apparatus. Background technique [0002] Generally, a fuel processing device for a fuel cell system may include a reformer, a CO shift converter, and a CO remover. [0003] The reformer generates hydrogen by reacting fuel gas such as methane with water vapor and by an endothermic reaction by means of a burner. Among them, carbon monoxide is usually contained in the hydrogen produced in the reformer. [0004] When such hydrogen containing carbon monoxide is directly supplied to the fuel cell system, the reaction catalyst is poisoned inside the fuel cell, thereby reducing the performance of the fuel cell. [0005] Therefore, it is necessary to remove carbon...
