It will be related to the electrochemical analysis apparatus and method for a catalyst for a fuel cell designed to be.

In general, a fuel cell is a power generation system that directly converts chemical energy into electrical energy, unlike conventional power generation methods that produce electricity by combustion of existing fossil fuels.

Most of the fuels are hydrogen and hydrocarbon series such as methanol. The fuel is classified into a low temperature fuel cell and a high temperature fuel cell according to the generation temperature.

The direct methanol fuel cell and the direct formic acid fuel cell, which are representative of the liquid supply fuel cell of the conventional low temperature fuel cell, have been actively researched and developed as a portable power supply source due to the ease of handling and the simplicity of peripheral devices.

This type of fuel cell has better energy conversion efficiency than conventional fossil fuel-generated systems, and can operate at room temperature, and thus can be applied to various fields such as automobiles, portable power supplies, and stationary power generation systems.

In spite of these advantages, the direct methanol fuel cell has a slow oxidation rate due to the cathodic catalyst, and due to the problem of poisoning the active point of the catalyst by carbon monoxide, which is a reaction intermediate, performance is accompanied.

In order to solve this problem, an anode catalyst having various compositions has been developed, but an alloy (molar ratio 1: 1) catalyst of platinum and ruthenium is known to be the best.

Direct formic acid fuel cells using formic acid have been effective using palladium-based catalysts.

The formic acid has a lower energy density per unit volume than methanol, but when it is supplied in aqueous solution, it acts as a strong electrolyte, thereby facilitating the transfer of hydrogen ions generated by the oxidation reaction at the cathode, and thus has excellent performance.

However, strong acid fuels such as formic acid inevitably cause side effects such as corrosion of the metal catalyst, and palladium-based catalysts are problematic in performance degradation due to catalyst poison when the battery is operated for a long time.

The catalytic performance of a fuel cell is a very important factor that greatly determines the performance of the overall cell.

However, due to various factors such as excessive overpotential of electrode due to low reaction temperature, adsorption of catalyst poisons such as carbon monoxide during oxidation process, and desorption of precious metal components due to long-term operation, the development of excellent catalysts is delayed and many research expenses are concentrated. Despite this, no clear research results have been produced.

For this reason, a study on high-throughput screening of fuel cell catalysts has been attempted, and this is mainly used in the development of new drugs, and some of them have been reported in US Pat. No. 6,284,402 and US Pat. No. 6,692,856.

USP 6,284,402 is characterized by the use of a fluorescent indicator sensitive to pH changes in the high-speed search for an anode catalyst for direct methanol fuel cells. This means that this method was first applied to the development of fuel cells with high-speed search.

However, there is a disadvantage in that quantitative data cannot be obtained for many combinatorial arrays, and the catalyst composition should be searched only based on methanol oxidation on-set potential.

US Pat. No. 6,692,856, unlike USP 6,284,402, has the advantage of yielding quantitative results.

However, there is a disadvantage in that precise catalytic activity comparison is impossible due to methanol and intermediate product concentration changes gradually changing as the fuel flows along the flow path, and the scalability of the combinatorial array is very difficult and expensive.

In addition, since the internal resistance of each cell is much larger than that of the conventional electrochemical half-cell experiment, there is another disadvantage that the comparison of the experimental results is impossible.

The present invention has been made in view of the above, and is a novel fuel that is quantitatively comparable to develop an electrochemically superior inorganic metal catalyst by applying a combination chemistry and a high-speed search technique to the fuel cell industry. It is an object of the present invention to provide an electrochemical analysis apparatus and method for developing a catalyst for a fuel cell that enables the search for a new fuel that can replace methanol or formic acid by applying phosphorus methyl formate.

In addition, the direct methyl formate fuel cell can derive an optimum ratio of the alloy catalyst that can obtain a high output at a higher voltage state, and can produce an alloy catalyst that can quickly compare the oxidation reaction of 220 candidate groups The purpose of the present invention is to provide a quantitative high-speed electrochemical analysis apparatus for developing a catalyst for a fuel cell.

In a preferred embodiment, the through hole of the fine hole plate is dispensed with an electrolyte solution containing fuel by an automatic dispenser, and the electrolyte solution containing fuel is in contact with the multicomponent alloy catalyst points, respectively, and the ions of all the electrolyte solutions. The fine hole plate is characterized in that the Teflon material so that the conduction is disconnected.

In a more preferred embodiment, the front end of the automatic dispenser is detachable to the micro-injector so that the counter electrode and the reference electrode can be sucked or dispensed at the same time or any one selected from the metal precursor solution, mixed solution, liquid fuel and electrolyte solution It is characterized in that combined.

In addition, the automatic dispenser is characterized in that the connection port is mounted so that the liquid fuel and the electrolyte solution can be dispensed through the fine injector.

The apparatus may further include a washer configured to store distilled water to wash the counter electrode and the reference electrode of the automatic dispenser.

In addition, the fine injector is characterized in that it can be automatically controlled up to several microliters.

In addition, the fine hole plate is characterized in that a plurality of holes are formed that can store the electrolyte of 30 ~ 900㎛ size.

The present invention relates to a high-speed search method for the development of a fuel cell catalyst by applying a high-speed search method widely used for the development of a wide range of materials in the pharmaceutical industry or biochemical industry in the fuel cell industry.

The present invention focuses on providing fast and quantitative comparisons, thereby providing an alloy catalyst having an optimum ratio.

In general, the fuel cell has a structure in which a hydrogen ion exchange membrane is interposed between the fuel electrode 10 and the air electrode 11.

The hydrogen ion exchange membrane has a thickness of 50 to 200 µm and is composed of a solid polymer electrolyte 12, and the cathode (fuel electrode) 10 and the anode (air electrode) 11 are respectively supported by an oxidation / reduction reaction of a support layer and a reaction gas for supplying a reactant. The catalyst layer 13 and the electron collecting plate 14 are formed.

Methanol oxidation reaction occurs in the anode 10 of the direct methanol fuel cell, and the generated hydrogen ions and electrons move to the cathode 11. Hydrogen ions moved to the cathode 11 are combined with oxygen to cause oxidation, and electromotive force by the oxidation reaction of the hydrogen ions becomes an energy generating source of the fuel cell. At this time, the reaction occurring in the anode 10 and the cathode 11 is as follows.

Cathode (fuel electrode): CH ₃ OH + H ₂ O → CO ₂ + 6H ⁺ + 6e ^- Ea = 0.04V

Cathode (air _{electrode): 3 / 2O 2 + 6H} + + 6e - → 3H 2 O Ec = 1.23V

Total reaction: CH ₃ OH + 3 / 2O ₂ → CO ₂ + 2H ₂ O Ecell = 1.19V

As can be seen from the above equation, since the performance of the catalyst in which the redox reaction occurs has a large effect on the overall performance of the fuel cell, the development of a catalyst for excellent methanol oxidation is a core technology of direct commercialization of the methanol fuel cell.

Synthesis of ruthenium on platinum has been reported to improve the resistance of the catalyst to the catalytic poisoning effect of carbon monoxide, and the preferred synthesis ratio is known to be an atomic ratio of 1: 1 (D. Chu and S. Gillman, J.). , Electrochem. Soc. 1996, 143, 1685).

This improved resistance to carbon monoxide is due to the ability of ruthenium to adsorb water molecules in the chemical potential of methanol adsorption onto platinum. It is understood. The relation is expressed as

Pt-CO + Ru-OH → Pt + Ru + CO 2 + H + + e -

Methyl formate, a liquid fuel that is attempted for the first time in the present invention, is a liquid fuel such as methanol and formic acid, and thus is easy to handle, and has a very high energy density per unit volume.

In addition, since methanol and formic acid are formed during the decomposition reaction, both of the advantages of the direct methanol fuel cell and the direct formic acid fuel cell can be taken.
