Description

  The present invention relates to a fuel cell power generation system test apparatus and a fuel cell power generation system test method for testing a fuel cell power generation system.

In recent years, there has been a remarkable increase in energy consumption, and in order to prevent global warming, it is necessary to reduce and suppress CO ₂ generated on a global scale. In order to reduce or suppress CO ₂ , it is essential to save energy or use highly efficient energy. All methods have been tried and put to practical use. A fuel cell power generation system (hereinafter sometimes simply referred to as “fuel cell” or “fuel cell unit”) has attracted attention as a high-efficiency power generation system. Since the fuel cell itself is directly generated by the chemical reaction between hydrogen and oxygen, the fuel cell is characterized by high power generation efficiency and the heat generated by the power generation is discharged. Therefore, the fuel cell is desired to be effectively used as a cogeneration system.

  There are several types of fuel cells depending on an electrolyte sandwiched between a fuel electrode supplied with hydrogen and an oxidant electrode supplied mainly with oxygen in the air. Among them, a solid polymer fuel cell using a solid polymer that allows hydrogen to conduct as H + (proton) from the fuel electrode to the oxidant electrode and combine with oxygen to generate electricity, From the viewpoint of operating temperature, it has been noticed and developed as a fuel cell with the fastest feasibility. The fuel cell power generation system that incorporates the polymer electrolyte fuel cell not only has high power generation efficiency, but also discharges hot water, so it can be used as a power source for small cogeneration systems installed in ordinary households and electric vehicles. The former is considered to be effective, and the former is now in the stage of mass production and commercialization.

  The fuel cell power generation system not only contains a solid polymer fuel cell alone but also extracts hydrogen-containing gas from hydrocarbon-based fuels typified by city gas and LP gas in order to transmit power to general households. Fuel treatment device, water treatment device for cooling and maintaining water quality, electric control device (inverter) that converts output DC power into AC, heat utilization device that recovers heat generated by power generation, and overall control It has a complicated mechanism not only for the fuel cell itself but also for the peripheral devices. Therefore, even if each highly reliable device is incorporated, there is always a manual part, so as a necessary inspection in quality control, the fuel cell power generation system test stand (a certain area for conducting tests) It is installed in the center and tests are conducted with power generation one by one for one day. In the phase of mass production / commercialization that exceeds 1000 units per year, if the average is simply averaged, the number of units produced per day will exceed 5 units, so additional test stands and increased efficiency per test stand are required. Improvement of the property is desired.

  Patent Document 1 is an example of a technique related to a fuel cell test method.

JP 2009-252561 A

  The fuel cell power generation system test stand that conducts the power generation test before shipment is not only configured with a radiator simulating installation in a general home, but also a power meter for determining pass / fail of the test, fuel flow rate Data collection device that collects necessary related data such as gauges, fuel pressure gauges, fuel thermometers, hot water flow meters, hot water flow thermometers, hot water return thermometers, operating status data in the fuel cell power generation system, and for test operations Various devices such as driving operation terminals used for the installation are installed. When the fuel cell power generation system is arranged on the test stand and the start operation is performed using the operation terminal, the fuel cell power generation system first executes the temperature raising program before starting the power generation. The fuel cell body generates power through a chemical reaction between hydrogen and oxygen. Therefore, the fuel cell power generation system is provided with a reformer for extracting hydrogen-rich gas from city gas or LP gas by a steam reforming reaction. The reformer is packed with a catalyst, and the reaction temperature varies depending on the type of catalyst, but a system that uses a catalyst type that causes a reforming reaction by raising the temperature to a temperature range of 600 ° C or higher is used as a conventional means. Therefore, the temperature is raised to that temperature range. When fuel is introduced into the reforming catalyst, a steam reforming reaction (endothermic) is performed in the reformer, and hydrogen can be taken out. The chemical reaction formula of methane gas is shown below as a representative example of the reforming reaction.

CH ₄ + H ₂ O → H ₂ + CO ₂ + CO
When the reforming reaction is performed, the hydrogen-rich gas is introduced into the battery body, so that power can be generated. Since the reforming reaction is an endothermic reaction, the temperature maintenance management is performed by burning the air and the burner using the hydrogen fuel that has not been consumed in the battery body.

  After completion of the power generation test, the operation operation terminal is used to perform the cooling operation until the reformer is forced to rotate the air blower used at the time of burner combustion to reach the ambient temperature level. Cooling takes approximately half a day to one day and is performed at a test stand where various devices are installed. If the cooling is not sufficiently performed on the way, for example, when the fuel pipe attached for shipping is removed and packed in a state of 100 ° C. or higher, the fuel processing system is used when the temperature drops from 100 ° C. or higher to room temperature. If the gas inside is shrunk due to a decrease in temperature, the pressure is reduced. There, outside air is sucked into the fuel pipe, or an extreme negative pressure state occurs, and the pipe may be deformed. For this reason, although the power generation test has been completed, nitrogen purge is performed using an operation terminal in order to drive out the fuel gas held in the fuel cell power generation system from the safety side. After the test, these operations are performed one by one on the test stand, but because of the long occupation time per test stand to which various devices are attached just for cooling and nitrogen purge, There is a problem of poor productivity.

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
First, a first embodiment of the present invention will be described.

  FIG. 1 is a diagram showing an example of the configuration of a fuel cell power generation system to be tested by the fuel cell power generation system test apparatus according to the first embodiment of the present invention. The fuel cell power generation system shown in FIG. 1 is also applied to a second embodiment described later.

  The fuel cell power generation system 10 mixes the fuel supplied from the fuel blower 12 and the water supplied from the water tank 13 through the water pump 14 to extract hydrogen from the fuel in the fuel cell main body 11. Then, it is introduced into the reformer 15 filled with the catalyst. The reformer 15 raises the temperature to 600 ° C. or more, which is an effective temperature for taking out the hydrogen-rich gas, and causes a reforming reaction.

When fuel gas and reformed water (steam) are introduced into the reformer 15, hydrogen, CO ₂ and CO are generated by the following equilibrium reaction.

CH ₄ + H ₂ O → CH ₄ + CO ₂ + CO + H ₂ O + CH ₄
Even if the reforming reaction is performed in the reformer 15, about 10% of CO is by-produced. Therefore, by passing the gas after the reforming reaction through the CO modifier 16 and the CO selective oxidizer 17, Reduce CO to several ppm level that is effective for power generation.

  In the CO denaturing device 16, the CO concentration is reduced by the following equilibrium reaction.

CO + H ₂ O → CO ₂ + CO + H ₂ O
In the CO selective oxidizer, the CO concentration is further reduced to several ppm level by the following oxidation reaction.

CO + O ₂ → CO ₂ + CO
As a result, a hydrogen-rich gas is introduced into the fuel electrode of the fuel cell main body 11, and an oxidant (air) is introduced into the oxidant electrode (air electrode) by the air blower 18, and power is generated by a chemical reaction. Since the reforming reaction in the reformer 15 is an endothermic reaction, the unconsumed surplus hydrogen rich gas that has not been consumed in the fuel cell main body 11 is used for temperature maintenance management. That is, the surplus hydrogen rich gas is mixed with the air supplied by the burner air blower 19 and burned by the reformer 15. As a result, the necessary temperature is maintained in the reformer 14.
