Description

Technical Field [0001] The present invention relates to an integrated reformer for a fuel cell system,

The integrated reformer for a fuel cell system according to the present invention includes a humidification chamber and a reforming reaction chamber having an independent structure formed by barrier ribs and a heat exchange process of the high temperature exhaust gas generated in the fuel cell stack, A plurality of heating channels and reaction channels are alternately arranged in order to generate hydrogen gas from the mixed gas, thereby maximizing the reforming reaction efficiency and thermal efficiency, providing a more compact structure of the reformer, So that the catalyst can be easily exchanged.

Many kinds of energy sources have been developed and used according to the development of science and technology including electric and electronic technologies. In particular, the demand for energy is increasing year by year, and energy production means using fossil fuel, nuclear power, hydro power, wind power, etc. are being used as a means of producing such energy. However, in order to cope with the environmental pollution problem caused by exhaust gas burned by fossil fuel and the energy crisis caused by depletion of fossil fuel, efforts for the development of pollution-free alternative energy are proceeding all over the world.

The use of hydrogen fuel as an alternative energy is meaningless as utilization of unlimited resources existing on the earth as pollution-free alternative energy. Fuel cell using hydrogen fuel is the core of hydrogen energy application technology, Is an alternative power generation means that can be used for electric vehicles, household use, power generation, etc., and is a means for supplying hydrogen gas and air as fuel and generating electricity by means of an electrochemical reaction between a pair of electrodes.

As a method for obtaining the hydrogen gas as a raw material of the fuel cell, a method using a reformer from a city gas or a natural gas, which is a main component of methane, which is now readily available in the case of using a fuel cell in an electric car or a household, It is possible to efficiently produce pure hydrogen by using hydrogen.

To explain the principle of the reformer producing hydrogen from methane, the reformer is equipped with a catalyst for the chemical reaction. In the steam reforming reactor module, methane gas reacts with water vapor, and carbon monoxide and carbon dioxide , And the remaining methane that was not reacted.

In the conventional reformer, one burner is installed in the lower part of the apparatus, and each module is heated by the heat generated from the burner to promote the chemical reaction by the catalyst stored in each module. However, there is a disadvantage in that a method of heating the respective modules installed at the lowermost part using the burner has a disadvantage in that a device for supplying fuel and air to the burner must be constituted. A reformer for generating hydrogen gas from the mixed gas and a heat exchanger for generating the mixed gas must be provided, respectively, and thus the size of the fuel cell system is disadvantageously increased.

A water inflow through hole 115 connected to the spray pipe 410 on one side of the upper portion of the quadrangular blocking plate 112 and an upper side of the humidifying chamber 120, And a plurality of discharge holes 117 are formed in the lower end portion of the heat transfer groove 116 to discharge hot water or steam to the humidifying chamber 120 An integrated reformer for a fuel cell system. The method according to claim 1,
The heating channel 100 is provided with a straight blocking plate 103 at both ends of a rectangular plate-shaped heating channel separator plate 101 and has a front surface of the heating channel separator plate 101 for promoting heat transfer of the exhaust gas, And a corrugated heating channel heat transfer fin (104) extending in the longitudinal direction to the inside of the blocking plate (103). delete The method according to claim 1,
The upper and lower portions of the humidifying chamber 120 are partially cut in the lateral direction to allow the fuel to flow in and the mixed gas to be exhausted. The humidification chamber 120 extends in the longitudinal direction to promote heat transfer of the exhaust gas, Wherein the fuel cell system comprises: The method according to claim 1,
The reforming reaction chamber 130 is provided with an upper heating fins 132 on the upper part of the mixed gas inlet groove 145 which are inclined upward from the lower side to the upper side of the mixed gas introduction groove 145 to promote heat transfer of the exhaust gas, A catalytic layer 133 in which a catalyst C for generating hydrogen gas from the mixed gas is accommodated in a lower portion of the upper heat transfer fin 132 of the reaction chamber and a catalyst layer 133 for promoting heat transfer of the exhaust gas to a lower portion of the catalyst layer 133 Wherein the lower portion of the catalyst discharge groove (142) is inclined toward the upper side of the hydrogen gas discharge groove (143), and the lower heat transfer fin (134) is formed in the corrugated reforming reaction chamber.
