る酸化ガス流入室である。In FIG. 2, numeral 1 is an electrolyte layer made of a fibrous sheet or mineral powder impregnated with phosphoric acid. Further, in the figure, 2 is an anode, and 3 is a cathode. Both the anode 2 and the cathode 3 are carbonaceous porous electrodes 1 whose surfaces in contact with the electrolyte layer 1 are usually coated with platinum as a catalyst. In the figure, reference numeral 4 denotes a fuel gas inflow chamber into which a fuel gas F containing hydrogen is introduced, and 5 is an oxidant gas inflow chamber into which an oxidizing gas (usually air) A containing oxygen is introduced.

Here, hydrogen is dissociated into hydrogen ions and electrons by the action of a catalyst. What is the reaction formula in this case?

Furthermore, the electrons separated by the dissociation of the hydrogen ions are released to the outside. The oxidizing gas A flowing into the oxidizing gas inflow chamber 5 performs work through the electric power load 6 and flows into the cathode 3.
The oxygen inside comes into contact with the catalyst through the pores of the cathode 3, which is a porous electrode, and together with the hydrogen ions that have migrated from the anode 2 side and the electrons that have returned to the cathode 3 through the external power load 6, the next generation is caused by the action of the catalyst. cause a reaction.

ところで上記の電池反応は発熱反応となるため電池本体
を冷却する必要があるため通常、素電池数セル毎に冷却
板を配置しこれに冷却水（約２００℃）を通流して冷却
している。By the way, since the above battery reaction is an exothermic reaction, it is necessary to cool the battery body, so normally a cooling plate is placed for every few cells of the battery, and cooling water (approximately 200 degrees Celsius) is passed through this plate to cool the battery. .

Therefore, the supply of cooling water for cooling the heat generated by the battery reaction as described above is configured such that the unit cells are divided into blocks of a certain unit quantity and branched to each block.
そこで、この燃料電池を運転する場合の冷却水の供給方
法について従来例を第３図の系統図について説明する。Therefore, a conventional example of a cooling water supply method when operating this fuel cell will be explained with reference to the system diagram shown in FIG.

，１２３・・・により制御するように構成されている。(Problems to be Solved by the Invention) As mentioned above, in the past, the fuel cell main unit cell, which is a stack of many unit cells, was divided into blocks for each unit quantity, and correspondingly, the cooling water supply piping was divided into blocks. To adjust the amount of cooling water, the flow rate is measured by the flow rate measuring orifices 111, 112, 113, and based on that, the cooling water amount adjustment valves 121, 122 are adjusted.

生することもある。又、通常、燃料電池本体に供される
冷却水の温度は約２００℃と扁温のため、一部に気相（
蒸気）を含むことがあり、これもオリフィスでの測定に
大きな誤差要因となることもある。However, the characteristics of an orifice for measuring the flow rate of cooling water generally tend to have a large measurement error near the upper and lower limits of the measurement range 10%. Further, depending on the mounting method and location of the orifice, differences in characteristics may occur between the orifices. In addition, the temperature of the cooling water supplied to the fuel cell body is usually about 200°C, which is a flat temperature, so some parts of the cooling water are in the gas phase (
vapor), which can also be a major source of error in orifice measurements.

となることもあった。Because of this, the flow rate measurement becomes inaccurate, and it is necessary to supply cooling water uniformly to each block 81, 82, 83, etc. of the fuel cell main body64. When cooling water is not supplied to each block, there is no problem for blocks to which cooling water is supplied at a rate higher than the required flow rate, but conversely, for blocks where the required flow rate of cooling water is not secured, the fuel cell main body of the block is In the case of phosphoric acid fuel cells, the electrolyte containing phosphoric acid begins to dry out and the fuel cell characteristics deteriorate, and the cell temperature continues to rise. Then, a hole appears in the electrolyte layer and finally 1. In some cases, the fuel gas and oxidizing gas directly mix, causing a crossover phenomenon, and the fuel cell itself may be fatally damaged, making it impossible to reuse it.

る様にしたことを特徴とする燃料電池装置。A pair of porous electrodes, an anode electrode and a cathode electrode, are arranged with an electrolyte layer in between, and a fuel gas is supplied to the back surface of the anode electrode, and an oxidant gas is supplied to the back surface of the cathode electrode, respectively,
In a fuel cell in which the electrical energy generated by the electrode chemical reaction is extracted from between the pair of porous electrodes, a large number of these unit cells are stacked, and the unit cells are divided into blocks of a certain number, and each block is Cooling water pipes are connected to the cooling water pipes, and a cooling water flow control valve is connected to the inlet side of each of the cooling water pipes, and similarly connected to the inlet and outlet of each of the cooling water pipes to control the cooling water inlet, A temperature measuring device that measures the outlet temperature and detects the temperature difference, and further compares the temperature difference of each block, and based on this compared value, calculates the amount of cooling water connected to each cooling water pipe. It is composed of a cooling water distribution controller that controls the control valve and adjusts the amount of cooling water supplied to each block of the fuel cell main body. A fuel cell device characterized in that control is performed so that blocks are the same.
