A reformer of a fuel cell system is disclosed. One embodiment of the reformer includes a reforming reactor generating reformed gas containing hydrogen by reforming hydrogen-containing fuel; and a CO remover removing carbon monoxide contained in the reformed gas generated from the reforming reactor, wherein the CO remover is disposed to be inclined in a predetermined angle to a moving path of the reformed gas exhausted from the reforming reactor and connected to the reforming reactor so as to communicate fluid therebetween, whereby the CO remover is not subject to the heat energy effect by a heat transfer effect due to air convection from the reforming reactor, making it possible to keep the CO remover an optimal state to improve reforming efficiency.

A fuel reformer using radiation comprises: a reforming reactor including a reforming catalyst for shifting fuel into a desired substance; a heater for supplying heat to the reforming catalyst; and a transparent inner wall positioned between the reforming reactor and the heater. With the present invention, the heat energy of the heater is transferred to the reforming catalyst in a radiation form so that the thermal efficiency of the fuel reformer can be improved.
摘要:
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.

Disclosed is a fuel cell system which includes a generator, a reformer generating a reformed gas by reforming a gaseous fuel and water and supplying the reformed gas to the generator. A fuel tank stores the gaseous fuel in a liquid state by compressing the gaseous fuel and supplying the gaseous fuel to the reformer. A water supply device supplies the water to the reformer. The water supply device includes a container connected to the fuel tank and the reformer and contains the water and the gaseous fuel with a pressure. A separation layer is formed on the surface of the water in the container for blocking a contact of the gaseous fuel with the water.

A fuel cell system includes a fuel cell stack, a reformer which generates a reformed gas through a reforming reaction between a gaseous fuel and water and supplies the reformed gas to the fuel cell stack, a fuel tank which compresses the gaseous fuel, stores the compressed fuel in an at least a partially liquid phase, and supplies the gaseous fuel to the reformer, a water tank connected to the fuel tank and the reformer to store water and to supply the water to the reformer by an internal air pressure of the fuel tank, and a first valve installed in a connection line connecting the water tank to the fuel tank to selectively open or close the connection line according to an electrical on/off pulse signal.
摘要:
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.
