A heater for heating a reformer of a fuel cell system includes a combustion chamber having a combustion catalyst layer; a distributor having an inner space and uniformly distributing a combustion fuel and an oxidant flowing along the inner space to the combustion catalyst layer of the combustion chamber; and an igniter igniting the combustion fuel and the oxidant, wherein the igniter is placed in the inner space of the distributor. Thus, the igniter is protected from combustion heat of the combustion catalyst layer and thus has improved durability.

Heater for fuel cell system

Disclosed are a carbon monoxide remover and a fuel cell reformer including the same. In the reformer, a reformed gas produced from a reforming reaction unit when the reformer is initially driven is used as a fuel for a heat source unit supplying heat to a water gas shift reaction unit. The carbon monoxide remover is connected to the reforming reaction unit that changes fuel into reformed gas with hydrogen. The carbon monoxide remover lowers carbon monoxide contained in the reformed gas. The carbon monoxide remover includes a heat source unit employing the reformed gas as a fuel; and a water gas shift reaction unit provided with a shift catalyst using heat from the heat source unit. The shift catalyst lowers the concentration of carbon monoxide in the reformed gas through reaction between water and carbon monoxide.

Carbon monoxide remover and reformer for fuel cell

A fuel cell system comprises: a fuel container for storing fuel liquefied with pressure; a reformer for generating hydrogen from the fuel through a catalyst reaction based on heat energy; an electric generator for generating electricity by transforming energy of an electrochemical reaction between hydrogen and oxygen into electric energy; a condenser for condensing water produced in the electric generator; and a heat exchanger passing through the condenser for cooling the condenser by latent heat of the fuel. With this configuration, cooling water cooled by latent heat of a fuel container is employed to cool the condenser without using a separate cooler. Furthermore, air is mixed with butane fuel without using a separate power unit, so that it is possible to achieve a more compact and highly efficient fuel cell.

A reformer that directly receives heat and performs an ATR catalyst reaction and an SR catalyst reaction. The reformer includes: a reforming reactor to reform hydrogen containing fuel into reformed gas having abundant hydrogen by performing an ATR catalyst reaction and an SR catalyst reaction; a heat source contacting one side of the reforming reactor and providing the reforming reactor with heat; and an air feeder to feed the reforming reactor with air by an air flow control unit. Thus, the ATR catalyst reaction featuring a relatively short preheating time is performed while the reformer is initially operated, so that hydrogen can be produced when the reformer is initially operated, thereby efficiently operating a fuel cell.

Reformer and fuel cell system using the same

A fuel reforming system and a fuel cell system including the same, the fuel reforming system including: a fuel reformer adapted to produce a reformed gas having hydrogen as a main component from a fuel containing hydrogen; a carbon monoxide (CO) remover adapted to remove carbon monoxide from the reformed gas; a heat source adapted to supply heat energy to the reformer and the CO remover; and a moving unit adapted to move the heat source between the fuel reformer and the CO remover. With this configuration, the fuel reformer and the CO remover can be directly heated by a heat source. Then, when the temperature of the CO remover reaches a catalyst activation temperature, the heat source can be moved to directly heat only the fuel reformer, thereby enhancing a reforming effect and a power generation efficiency of the fuel reforming system.

An apparatus for supplying mixed fuel includes a water container storing water; a fuel container storing fuel, including at least gaseous fuel, the fuel container being coupled to the water container by a pressure pipe for transferring internal pressure of the fuel container to the water container; and a mixer coupled to the water container through a water supplying pipe and coupled to the fuel container through a fuel supplying pipe, the mixer outputting mixed fuel through a mixed fuel supplying pipe. A water supplying unit includes a water container storing water and connected to a water supplying pipe, the water container having an outlet; and a pressure applying unit coupled to the water container for applying gas pressure to an inside of the water container to discharge water from the water container through the outlet.

A reformer is disclosed for supplying a reformed gas containing hydrogen to a fuel cell. The reformer comprises a heat source; a preheating portion preheated by heat from the heat source; a pipe shaped reforming reaction unit; a carbon monoxide processing unit extending from the reforming reaction unit; and a rugged portion installed on an internal surface of the pipe shaped reforming reaction unit which is heated by the heat source. By using the rugged portion and the extended pipe design, the area heated by the heat source is increased and more heat is recovered, thereby improving thermal efficiency.
