A fuel cell is a device that converts chemical energy into electrical energy through electrochemical reaction of hydrogen and oxygen. It has high efficiency and almost no emission of pollutants. (PEMFC), Solid Oxide Fuel Cell (SOFC), and Molten Carbonate Fuel Cell (MCFC).

Reforming of hydrocarbon fuel and decomposition of water are typical methods of producing hydrogen used as a fuel of fuel cell. Hydrogen production method through decomposition of water should supply energy more than energy generated when hydrogen is burned. The efficiency is low. Therefore, the hydrogen production method through the reforming of the hydrocarbon fuel is the most efficient hydrogen production method considering the present technology level and economical efficiency.

Modification methods of hydrocarbon fuels can be classified into partial oxidation (POX), steam reforming (SR), and automatic thermal reforming (ATR) depending on the reactants supplied with the fuel.

Hydrogen peroxide is generally colorless and odorless, and is well soluble in water and widely used in the manufacture of disinfectants, bleaches, oxidants, and derivatives. In addition, the characteristics of hydrogen peroxide are non-toxic, harmless to the human body, have no chemical reactivity with the atmosphere, and have low vapor pressure (for example, when the concentration of hydrogen peroxide is 90 wt%, the evaporation pressure is 0.2 kPa at 30 ° C., (Eg, evaporation pressure of 5,080 kPa) and high specific heat (eg, 2.52 J / g · ° C at 100% concentration of hydrogen peroxide).

From the viewpoint of oxygen storage and supply, the oxygen storage density at 25 ° C is about 21 molO ₂ / liter at 1 bar for hydrogen peroxide, while 485 bar, 5 ° C is needed for 21 mol O ₂ / liter for liquid oxygen. In addition, hydrogen peroxide maintains a liquid state at room temperature and can be stored in a suitable container for a long period of time. Therefore, it is advantageous in that the storage efficiency per volume is relatively high since there is no need to insulate the storage tank or piping such as liquid oxygen.

The temperature of the reaction gas is reduced through heat exchange in the heat exchanger 200. The relatively low temperature reaction gas whose temperature has been lowered through heat exchange in the heat exchanger 200 is discharged through the reaction gas outlet 300 And the water vapor and oxygen decomposed from the aqueous hydrogen peroxide solution that has been discharged through the heat exchanger are injected into the upper end portion of the reactor 100 through the oxidizer line 500.

Here, the heat exchanger must be designed so that the temperature of water vapor and oxygen that is decomposed from the hydrogen peroxide solution and exits the heat exchanger is maintained in the gaseous state in the reactor and is supplied for the reforming performance.

The design variables of this heat exchanger are the overall heat transfer coefficient (W / (m ² · K)) of the heat exchanger, the heat transfer area (m ² ) The temperature of the aqueous solution, and the type of the heat exchanger in the present invention is preferably a form that is combined with the reactor.

The fuel supplied to the reactor 100 can be used without limitation as a gaseous fuel or a liquid fuel, and when the gaseous fuel is used as a fuel, it can be mixed with the gaseous fuel after steam and oxygen are introduced into the reactor, A fuel line 400 connected to the reactor and an atomizer 600 capable of raising the atomization and atomization characteristics at one end of the oxidizer line 500 may be further included to enhance the reforming efficiency as shown in FIG. 3 or FIG.

The spray device 600 mixes and atomizes the fuel supplied through the fuel line 400 and the steam and oxygen supplied through the oxidizer line 500 to contact the catalyst layer provided in the reactor 100 I make it.

In the autothermal reforming reactor for fuel cells of the present invention, the ratio of the fuel and the oxidizer can be adjusted so that the autothermal reforming reaction condition becomes an exothermic reaction within a safe range when the hydrogen peroxide solution is used in the reactor, and thus the concentration of the hydrogen peroxide solution can be controlled .

Therefore, the autothermal reforming reactor for a fuel cell using the aqueous hydrogen peroxide solution of the present invention calculates the steam to carbon ratio (SCR) and the oxygen to carbon ratio (OCR), which are the autothermal reforming conditions, Carbon ratio) and oxygenated to carbon ratio (OCR), the hydrogen peroxide solution can be supplied by calculating the concentration of the aqueous hydrogen peroxide solution.

Specifically, decomposition reaction of hydrogen peroxide at a concentration of 100 wt% proceeds as shown in the following reaction formula 3, and 1 mol of hydrogen peroxide (H ₂ O ₂ ) is decomposed to produce 1 mol of water (H ₂ O) Of oxygen (O ₂ ).

The autothermal reforming (ATR) reaction is as shown in Scheme 4 below. Hydrogen, water, and carbon dioxide are produced by an exothermic reaction in which an aqueous hydrogen peroxide solution is supplied as an oxidant together with fuel and water as a reactant.

Here, the Oxygen to Carbon ratio (OCR) is the molar ratio of the supplied oxygen (O ₂ ) to the fuel. OCR is the ratio of the number of moles of oxygen generated when the hydrogen peroxide is decomposed by the total number of moles of carbon, and the steam to carbon ratio The molar ratio of water vapor (H ₂ O) and fuel supplied represents the molar ratio of carbon to steam.

The Oxygen to Carbon ratio (OCR) and Steam to Carbon ratio (SCR) values can be calculated with reference to the above reaction formulas 3 and 4, and the concentration of the aqueous hydrogen peroxide solution can be calculated from the values of SCR and OCR.

That is, the autothermal reforming reactor for hydrogen fuel cells using hydrogen peroxide according to the present invention can make the reforming reaction of most hydrocarbon fuels into autothermal reforming reaction by controlling the concentration of aqueous hydrogen peroxide solution. This means that carbon deposition is slow in calculation of calorific value and chemical equilibrium composition The hydrogen peroxide concentration, excluding the amount of carbon produced, can be obtained through thermodynamic calculations.

For example, an aqueous hydrogen peroxide solution _{(H 2 O 2 (aq)} ) from the result of calculation by fixing the carbon to steam ratio SCR to 3.0 according to the concentration, the aqueous hydrogen peroxide solution _{(H 2 O 2 (aq)} ) the concentration is 20, 30 of the , 40, and 50 wt%, the values of OCR change to 0.18, 0.28, 0.39, and 0.52, respectively. That is, as the concentration of hydrogen peroxide solution increases, the value of OCR, which represents the mole ratio of supplied carbon to oxygen, increases gradually.

In one embodiment, the thermodynamic calculation results for calculating the concentration of aqueous peroxide depending on the type of fuel to make the autothermal reforming reaction conditions are as follows, wherein the equilibrium composition and the heat of reaction in the thermodynamic calculation correspond to the reaction temperature and 1 atm ), The value obtained when the Gibbs free energy becomes the minimum value. The temperature of the supplied fuel was set at 25 ° C and the temperature of the supplied water vapor (H ₂ O _(g) ) and oxygen (O _{2 (g)} ) was set at 150 ° C.

In an embodiment of the present invention, the autothermal reforming reaction temperature in the autothermal reforming reactor is 400 To 900 ° C, and the fuel may be methane, ethanol, gasoline, kerosene, diesel, gas-to-liquid (GTL) fuel, or the like.

The thermodynamic calculation results for methane (CH ₄ ) fuel are as follows: SCR = 3.5, OCR = 0. 6, and thus the concentration of aqueous hydrogen peroxide solution for autothermal reforming reaction is 49.6 wt%. This reforming reaction of methane fuel is shown in the following reaction formula (5).

As a result of thermodynamic calculation of gasoline fuel, the conditions under which autothermal reforming occurs at 600 ° C SCR = 3.0, OCR = 0.5, and thus the aqueous hydrogen peroxide solution concentration for the autothermal reforming reaction is 48.6 wt%. The reforming reaction of the gasoline fuel is as shown in the following reaction formula 6, wherein the gasoline fuel is iso-octane.

The thermodynamic calculation results of diesel fuel using autothermal reforming at 600 ℃ showed that SCR is 3.0 and OCR is 0.5, and the concentration of aqueous hydrogen peroxide solution for autothermal reforming is 48.6 wt%. The reforming reaction of the diesel fuel is as shown in the following reaction formula 7, wherein the diesel fuel uses n-dodecane as a substitute fuel.

Since the number of carbon atoms contained in each of the fuel types differs depending on the fuel, the values of the chemical reaction coefficients vary depending on the number of carbon atoms in the same SCR and OCR values as in the reaction formula 4, and the Gibbs free energy minimization Gibbs free energy minimization) are different from each other, the enthalpy change (ΔH) is different.

If the autothermal reforming reaction under exothermic condition is controlled by adjusting the concentration of the hydrogen peroxide solution, it is possible to perform the thermally self-sustaining operation without the external heat source, and has a relatively high hydrogen yield and a relatively fast response speed. In addition, there is an effect that the thermal efficiency can be increased by recovering heat generated during autothermal reforming.

In the present invention, the concentration of the aqueous hydrogen peroxide solution is such that, when the concentration of the aqueous hydrogen peroxide solution is 67 wt% or more, considering the heat of decomposition of the aqueous hydrogen peroxide solution, the aqueous hydrogen peroxide solution generates heat capable of raising the temperature to the boiling point, Which generate steam and oxygen, and may cause safety problems in storage and supply due to the volume expansion due to abrupt gas generation.

However, in case of less than 67wt% aqueous hydrogen peroxide solution, all of the decomposition heat from the decomposition reaction is used as the heat of evaporation of water in the aqueous solution, and the decomposition products are water and oxygen. Therefore, in the present invention, it is preferable to limit the concentration of the aqueous hydrogen peroxide solution to less than 67 wt% in consideration of safety in storage and supply when using an aqueous hydrogen peroxide solution in an extreme underwater environment.

As described above, the present invention provides an aqueous hydrogen peroxide solution with a controlled concentration as an alternative oxidizing agent for the reforming reaction. This concentration of hydrogen peroxide solution is decomposed into water and oxygen, which are the oxidizing agents of the autothermal reforming reaction, through the heat exchange with the reaction gas heat generated by the autothermal reforming reaction in the heat exchanger, so that the hydrogen peroxide can be used even under oxygen- Thereby providing a autothermal reforming reactor for a fuel cell.

In addition, if an aqueous hydrogen peroxide solution is used as an oxidizing agent, it is possible to increase the oxygen storage efficiency as compared with the case where liquid oxygen is used, and it is not necessary to supply the supplied oxidizing agent with an additional heat source so as to provide a miniaturized autothermal reforming reactor for fuel cells have.

It will be apparent to those skilled in the art that the embodiments described above may be embodied in other specific forms without departing from the essential characteristics of the present invention. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. It is also intended that the scope of the invention be determined by rational interpretation of the appended claims and that all changes which come within the spirit and scope of the invention, Are included in the scope of the present invention.
