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.
Abstract:
A fuel reforming apparatus includes an oxidation reaction unit in which an oxidation catalyst is formed, a reforming reaction unit in which a reforming catalyst is formed, and an ignition unit for igniting a hydrocarbon-containing fuel and an oxidant and preheating the oxidation catalyst in an early driving stage. The oxidation reaction unit has a first section and a second section respectively formed opposite to each other with the oxidation catalyst interposed therebetween and forms a stream of the fuel and the oxidant flowing to the second section through the oxidation catalyst from the first section, the ignition unit being located in the second section.
Abstract:
A fuel cell system includes a reformer for generating hydrogen gas from fuel containing hydrogen using a chemical catalytic reaction and thermal energy. At least one electricity generator generates electrical energy by an electrochemical reaction of the hydrogen gas and oxygen. A fuel supply assembly supplies fuel to the reformer, and an oxygen supply assembly supplies oxygen to the at least one electricity generator. A heat exchanger is connected to the reformer and to the at least one electricity generator. The heat exchanger supplies thermal energy of the reformer, during initial operation of the system, to the at least one electricity generator so as to pre-heat the at least one electricity generator.

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.
