れる。In the figure, 1 is the fuel cell body, 2 is the air electrode gas space, 3 is the fuel electrode gas space, 4 is the air electrode, 5 is the fuel image,
A conductive wire 6 connects a load 8 between the air electrode (anode) 4 and the fuel electrode (yin-dong) 5. The control device 9 of the fuel cell uses the following method for controlling the air and fuel flow rate to the battery main body 1. - Control of the air and fuel flow rate to the battery main body 1 is performed first by controlling the output of the tun pond. ``The current is detected by the first-line detector 7 and inputted to the function generating elements (function generator or microprocessor) 11 and 12. Function generation element 11.12
For example, as shown in FIG. 2, the relationship between the output current IDC and the air or fuel flow rate is set as a previously predicted function. This function value usually has the same output′
The flow rate on the air side is set to about four times that on the fuel side with respect to the current value.

る。Passing through this function generating element therefore provides the desired air and fuel flow settings for a given output current. Furthermore, this output is passed through a function generating element 13.14 representing the relationship between the flow rate of air and fuel and the opening degree of control valve 81. Control valve 31.32 1t1

側に比べ空気極４９１１１の流量の方が２倍も多く゛電
極を通過するために、空気極側の圧力変化が大きく現わ
れることによるものが主な原因と考えられる。By the way, especially in the case of fuel cells manufactured by phosphate manufacturers, the hardware structure of the cell body 1 makes them extremely vulnerable to the pressure difference (hereinafter referred to as differential pressure) between the air electrode 4 and the fuel electrode 5. . Therefore, when the flow rates of air and fuel are controlled according to the above-described procedure in response to changes in electrical load, this differential pressure is transiently generated at the battery base 1. This is fuel electrode 5
The main cause is thought to be that the flow rate at the air electrode 49111 is twice as large as that at the air electrode 49111 and passes through the electrode, resulting in a large pressure change on the air electrode side.
この差圧がある値以上大きくなると、電池の破壊に至る
か、そうでなくても電池本体材料の劣化を紹き、寿命の
低下をきたすことにつながる。If this differential pressure increases beyond a certain value, the battery may be destroyed, or even if not so, it may introduce deterioration of the battery main body material and shorten its lifespan.

にある。In view of the above-mentioned problems, the door roller that is the object of the present invention is equipped with a differential pressure detector between the air and fuel electrodes, and also incorporates this differential pressure signal as a control signal for the gas flow rate to the battery body.
By correcting the control valve (tlli) using this signal, the fuel cell can control the gas flow rate in winter in response to electrical load changes while suppressing the differential pressure within a predetermined value. An object of the present invention is to provide a gas flow rate control device.

るためのものである。If this opening command is directly issued to each control valve a1.82, a high differential pressure change will occur on the air side. Therefore, this differential pressure is detected by the differential pressure detector 15 and PIDID is detected.
It is passed through the controller 167 and added to the outputs of the rJJ number generating elements 18 and 14 of each of the air electrode 4 and the fuel electrode 5. The polarity of No. 1i to be added is selected so as to suppress the differential pressure generated only by the feedforward Vii control. 1) ID
