[Prior art] The viscometer traditionally disclosed in Japanese Examined Patent Publication (Case) No. 2,654,648 is a technique for measuring ethanol / centre in water and ethanol solutions, as is known. The traditional technology includes a quartz resonance contacting a liquid sample ^ and a resistance element for setting an equivalent circuit of the quartz resonator as a viscosity measurement device for the viscosity index of the liquid sample, which lacks a frequency measurement impedance near the frequency of the quartz resonator The value is used to calculate the viscosity from the calculated impedance value. [Summary of the Invention] A direct-modification fuel cell system uses a viscometer for a fuel cell measurement device. The structure shown in FIG. Directly modified fuel cell:-Fuel cell b-Air pump 2 is used to supply air to the fuel cell, which is required for the gas electrode U,-Methanol / water container 3 is used to hold methanol for fuel: liquid : And a methanol / water pump 4 is used for the fuel electrode 12 supplied by the methanol / water container 3 as fuel A: Xuan read 'I and T% cold shoe. At the same time, a methanol measurement used to monitor methanol concentration in Jianqin 5 11 fuel was placed at the liquid layer of methanol / water. Located on a fuel cell! Numbers]-Film. τ j Μ Heart ice electrolyte 1 μ% ethanol / ethanol concentration of the remaining battery system fuel need to be prepared. In order to be detected, the following problems are required (1) Bubbles attached to the methanol measuring device 5 are one of the problems. 87698 1227574 [Chemical reaction formula 1] CH3〇H + H20- ^ 6H ++ 6e '+ C02 When the above reaction is generated at the anode electrode (fuel electrode i2) of the fuel cell due to power generation, the solution mixed with: carbon oxide is Continuously evacuated to methanol / water order 3. Therefore, the carbonized gas bubbles tend to adhere to the methanol measuring device 5 of the methanol / water container 3. When the reaction temperature of the fuel cell i is relatively high, the solution will tend to evaporate 'while methanol bubbles and steam will tend to erupt. Therefore, the detection accuracy of the methanol measuring device 5 will be reduced. (2) Impurities attached to the methanol measuring device are one of the problems. The methanol / water-like solution stays in the methanol / water container 3 and the flow amount is small, so that impurities tend to adhere to the methanol measuring device 5. Therefore, the detection accuracy of the measuring device 5 is reduced. $ Because the aforementioned problems and the characteristics of traditional viscometers have the following problems: 1 (1) Even when the concentration is the same, the oscillation frequency will vary with the temperature of the liquid being measured, so it should be fully adjusted This difference. (2) If foreign matter adheres to the quartz resonator part, it cannot be measured. Therefore, estimates should be used. (3) When the power generation reaction of the fuel cell generates bubbles in the methanol solution used as the fuel, the measurement should be taken before this and not affected by it. (4) When the temperature of the methanol solution increases, the detection characteristics of the deteriorated quartz resonator 'should be reduced to an appropriate temperature. The present invention has been completed in consideration of such conventional technical problems, and the object of the present invention is to provide a directly modified fuel cell system, which can measure 87678 1227574 related liquid "temperature and solution bubbles to accurately Measure the methanol concentration.

The flow in the constant passage 40 is thereby increased so that the methanol measuring device 5 is at a liquid level, as shown in Fig. 8 (a). Battery system ’bubbles are stuck in place -20-1227574 Methanol denier under liquid. ^ ^ I the surface of the rigid device 5 and move it away from the liquid to contact the Ding .. ', meters / bag' and then make the methanol measuring device 5 under the liquid, and accurately measure the rigidity in double to less degree Methanol ::: # Methanol concentration was measured. Therefore, in this specific example, φ ^, τ ^ ^, the flow of a methanol / water methanol / water-like solution on the branch 41 will not be used under normal operation π 3 ^, 7 and will not be affected. The heat generated by the power generation reaction ^. ',, heating, so that the branch 41 operates as the same cooling path' It can temporarily reduce methanol / water methylase during the measurement of A, Qu Ling / Chen degrees / Water-like solution temperature, from B Tianpan,-can improve the measurement accuracy. The direct modification of the fuel cell system of the specific example of Yidi Seven, ^ Riri, ~, Λ Yidi Seven, will take the participant _ Gu 9 as the example. A specific example of the fuel cell system is characterized in that it is provided in the methanol / water column, the 4th meter measuring device 5 at the output port, and the methanol / pump 4 spokes at the inlet end and the output end with pipe fittings 7, 8 and the vibration absorbing joints 51 and 52 are connected. The reference number 53 represents the damping for the pump 4. During operation, the methanol / water system 4 vibrates. Therefore, its output port vibrates together, and if the detector 5 is set At the output port, the air cores and reductions attached to its surface can be removed by the vibration of the methanol / water pump 4 so that its surface can always be kept clean. 口 Q'This is a direct-modified fuel cell according to the seventh specific example The system can prevent bubbles and impurities from adhering to the methanol measuring device 5 and can measure the methanol concentration with high accuracy. Then, a directly modified fuel cell system according to an eighth embodiment of the present invention will be described with reference to FIG. 10. The characteristics of this specific example are set: the orientation of the two Hantian, Ε! Ί, Τ- 里 J state 5. Please refer to the methanol measuring device shown in Figure 10 (a) is set 87698 -21-1227574 In pipe fitting 60; where methanol / water methanol / water is soluble The flow of liquid makes its sensing surface parallel to the flow direction of liquid 61. Compared with the way that the sensing surface shown in Figure 10 (b) is at a right angle to the flow direction of liquid 61, this can reduce bubbles and The amount of impurities attached. In this specific example, FIG. 11 shows the sieve holes or porous filters 63, the arrangement of which does not interfere with the flow of the liquid, so that it covers the methanol measuring device 5, which can further reduce the adhesion to the methanol measurement. The number of bubbles and impurities on the surface of the device 5. Next, a direct-modified fuel cell system according to a ninth specific example of the present invention will be described with reference to Figs. 12 to 14. When the temperature of a methanol / water methanol / water-like solution due to power generation The response becomes higher, and it is difficult to measure the methanol concentration through a methanol measuring device. Therefore, FIG. 12 shows a specific example of a fuel cell system characterized by a control circuit 20 having a current amount through power generation, input methanol, and efficiency comparison. Figure, the circulation flow of the solution, the amount of methanol released outside the system, and the temperature of the solution, the function of estimating and calculating the concentration of methanol. Figure 12 shows the directly modified fuel cell system A solid polymer fuel cell including the first specific example 1, an air pump 2 for supplying air to the fuel cell 1, an air electrode 11, a methanol / water container 3 for containing methanol and an aqueous solution for fuel, and A methanol / water pump 4 is used to supply a methanol solution from a methanol / water container 3 to a fuel electrode of a fuel cell. A methanol pump 72 is used to supply methanol as fuel to the methanol / water container 3 from a methanol container 71. Reference number 73 is connected to Gas / liquid separator of the fuel cell 1. The fuel cell system of this specific example includes a control circuit 20 for controlling a driving device. The control circuit 20 has a driving circuit 21, an output control circuit 22, a central processing unit 23, and a Efficiency comparison chart storage section 24, and controlling the methanol concentration and output of power generation of 87678 -22-1227574 methanol / water methanol / water-like solution. To perform this control, it is constructed that the methanol concentration signal is input by the methanol measuring device 5 and the battery temperature signal and the generated current / voltage signal are input from the temperature measuring device 74 as necessary information. In order to monitor the temperature of the solution, the methanol concentration measuring device 30 has a mountable structure as shown in FIG. 7; but in this specific example, a temperature signal of a battery temperature measuring device 74 for monitoring the reaction of the fuel cell 1 is provided together with the setting The methanol measuring device 5 is used in a methanol / water container 3. As shown in Figure 13, when the direct-modified fuel cell system is used to charge the second battery of the electric-assisted bicycle, when the nickel-cadmium battery is used like the second battery, the battery can be discharged by itself before recharging. To charge the second battery. The control circuit 20 monitors the discharge condition of the second battery, and when it is completely discharged, starts the fuel cell system to recharge the battery (self-discharge monitoring mode (i), low power consumption mode (ii)). When the electric-assisted bicycle is in operation, this mode is switched to the driving mode (iii) 'and the control circuit 20 responds to the charging condition of the second battery and controls the power generated by the fuel cell system. In the driving mode (iii), when the fuel cell system reacts to generate electricity, the temperature of the methanol / water methanol / water-like solution increases. Therefore, the temperature may rise higher than the allowable temperature of the general methanol measuring device 5 of the ultrasonic type or the quartz resonance type, which makes it difficult to measure the methanol concentration. Therefore, in the fuel cell system of this specific example, the control circuit 20 monitors the temperature of the methanol / water methanol / water-like solution, as shown in the flowchart of FIG. 14 (step S11); when the temperature is within the range of the measurable concentration, it is measured. Concentration, the amount of methanol to be calculated based on the measured methanol concentration, and the amount required to control the methanol / water container 3 from the total of 87678 -23-1227574 fermentation container 7H (step back to the other 10,000, if Step su The measuring device 5 performs the concentration measurement. The output of female vision can be used when the methanol degree is too high, the amount of methanol, the amount of input methanol or similar alcohol concentration, and the estimated m based on the concentration. 'VS13) Estimate A S14) 〇, the work load should supply < the amount of methanol (steps to estimate the methanol concentration procedure, from the secret ▲ a ^, efficiency comparison chart, solution cycle denier current, the amount of input methanol, ^ Miles, Fenson released outside the system, and Fenson estimate the methanol concentration based on the solution temperature in the flow chart in Figure 16. Long = Measure the methanol concentration test value when the system is started and the temperature is low (step S21). 1 to determine the temperature Whether the condition is suitable for measurement (step s22). (3) For example, 'when monitoring the second battery self-discharge procedure and the concentration of the product, people can be measured, measure nail jealousy, jinjia and / chen The temperature is in (steps S22, S23). The concentration of the water-like solution and the updated reference value: Measure the voltage, current, and battery temperature of the fuel cell, as shown in Figure 15 Consumption (; =): The efficiency of current and temperature is compared with the estimated theory in Figure 24, which is described as follows: The heat generated by 1 methanol per melon is 18.2 [kJ / ml]. T. Pitch, C. The amount of methanol consumed is calculated by multiplying the above value by the efficiency of the monthly color / efficiency ^ ^ ± IL · The amount of methanol consumed. The heat generated by the mother in the early stage (18 · 2) = The amount of canceled 87698 -24-1227574 is inappropriate. The amount of methanol released outside the system is calculated based on the previously registered atmospheric temperature-evaporation comparison chart, and the amount of methanol retained by P pieces (step S25). Calculate the amount of methanol needed to calculate the measured methanol concentration According b):: the number of operators required to supplement, by the addition of methanol known to methanol in a container of water for each 71 3 (step S27) and no lack of the complement number (step S26) to (A 7) methanol consumption quantity calculation. The ίί: period '-a very small amount of methanol is released from the system, but it can be adjusted by a large μ, or simply added-a predetermined amount of li, the cycle time of the concentration of A can be a fixed interval, such as Minutes and every ten minutes' and consumption is μ in the system). Shuijia :: According to the specific example of the fuel cell system of Λ9, even when the methanol / θ temperature rises too high, and the general methanol measuring device 5 estimates and supplements the equivalent amount due to alcohol * 'can be used in the control circuit 2〇 The medium pre-maintained at an appropriate value. The methanol concentration of a water-like solution can be followed by 'the lesson and pool system according to the present invention. In the future, consider Figure 17 = Ten specific examples of direct modification of fuel. The characteristic lies in the fuel cell system with the " two taking this specific example. To replace the efficiency comparison of the ninth specific example by copying the A-H sequence ../ Chen degree your function. Its hardware structure is shown in Fig. 12, which is similar to the concrete example of Yanjiu. According to the fuel cell $ &, 3 &, the methanol concentration control of the example, the implementation is as follows: 87678 -25-1227574: (1) Measure the current value fixedly, and multiply the current by the time interval to calculate the current amount (step 骡S31). (2) The calculation of energy conversion into current is as follows (step S32). First, the reaction of the fuel cell is as follows. [Chemical reaction formula 2] CH30H + H20— 6H + + 6e_ + C02… react at the anode (fuel electrode) 6H + + 6e- + 3/2 02— 3H20… react at the cathode (air electrode). The charge of each electron is 1.60 × 10-19 C, and the charge of each mol of methanol is about 57.8 × 10 4 C. Since the current is charged per unit time, if the current is monitored, the amount of methanol converted into current can be calculated. Amount of electric current / charge per mol = number of energy converted into electric current. (3) Next, calculate the heat (loss) of the chemical reaction (step S33). The heat generated by the chemical reaction between the cathode (air electrode) and anode (fuel electrode), which is known as the entropy loss (B), is registered in the control circuit 20 in advance. (4) Next, the efficiency is calculated from the voltage of the fuel cell (step S34). The theoretical voltage of a single cell is known as 1.2 V, so that the calculation of the voltage loss can be calculated from the fuel cell voltage. (1.2—the measured voltage of a single battery) /1.2=voltage loss (C). (5) Next, calculate the energy generated by methanol (step S35). (A) / (C) + (B) = energy consumed (D). (6) Calculate the amount of methanol consumed (E) from the energy generated by methanol. (D) / Total heat of methanol 18.2 kJ / ml = Amount of consumed methanol (E). Continuously monitor the current and voltage generated in the fuel cell 1, and calculate the consumption as described in 87678 -26-1227574 above.> @ 泵 72 by methanol capacity crying, the equivalent amount of snails and shoulders Replenish to methanol / water container 3 with each state 71 of methanol. At start-up, the methanol measuring device 5 measures within the reference range, in degrees. If the value is not in the position of the fuel cell system according to the specific example, in the second number ... alcohol. The τ alcohol concentration is the most water-like solution in the alcohol measuring device 5. Refer to Fanyuan. Take J / Chendu to measure, can be located in the mother of the present invention-and bribe / 丨, the tester 5, or will be A ;; 1 can be used in the ultrasonic type as the W-quantity measurement of a degree measurement device 30 Quartz resonance type. In the -1 state, 32 d is replaced.

The state is superficial, so it can be highly ':, measure the concentration of methanol' and control the concentration of methanol. Department I: Direct-modification fuel cell in the 9th scope of the invention application patent: In methanol, the concentration will depend on the temperature of the methanol / water-like solution: 'The concentration of methanol can be accurately measured by adjustment. And to be accused of crying Lu said that when using a methanol amount such as Shiyang resonance type or ultrasonic type, the amount of methanol: Temple's calculation of the concentration of methanol based on the viscosity of the liquid, was affected by the temperature of the loose shape. It is stated that the direct modification fuel cell of the M range of the patent application of the Qing Dynasty ', & system has a voltage and temperature conditions corresponding to the current generated by the fuel cell power generation 87678 -27-1227574 pressure and temperature conditions.
