Abstract

PURPOSE:To provide a fuel cell in which the clamping pressure of a cell stack can be regulated easily. CONSTITUTION:A supporting stand 4 is constituted of a fixing stand 6 which is used for fixing an upper clamping bar to a pressure case through a clamping rod 5, and a lower clamping plate 7 which is used for clamping a cell stack 1 used for a fuel cell by pressing the stack 1 upward from its lower side. The plate 7 is connected to a pressure transmission bar 8, which is used for pushing up the plate 7 from the outside of a pressure case 3. The bar 8 is connected to an actuator 10 which converts a pressure fluid, which is supplied from mechanical a pressure-fluid supplier 9 used as a pressure supplying source, into mechanical energy. As a result, the looseness of clamping pressure which is caused due to repetitions of driving and stopping can be regulated easily by controlling the pressure of the pressure fluid supplied from the pressure-fluid supplier 9.

[Detailed Description of the Invention] The present invention is an alkaline electrolyte fuel cell, an acidic electrolyte fuel cell #! Regarding fuel cells such as molten carbonate fuel cells, the tightness of the fuel cell stack is a superimposed factor that directly affects the pressure control #i electric performance. Internal contact resistance becomes smaller. However, if the tightening pressure is too high, the electrolyte will seep out to the gas side of the electrode.

On the other hand, if the tightening is insufficient, there will be a problem of gas leakage. In the past, little consideration was given to this point, and as shown in Figure 1, the upper part of the fuel cell stack 1 was tightened using par 2, and the pressure vessel 3 was fixed to the support base 4. It is tightened with rod 5.

This tightening work is done manually. It is unavoidable that there are variations in the rounding and tightening, and that the degree of tightening deviates from the optimum value. Another problem is that, as shown in Figure 1, the fuel cell itself is housed in a pressure vessel during operation, and as the operation is stopped many times (temperature rise, cooling, pressurization, pressure reduction), the screws become loose. This is what happens. As a result, the above-mentioned increase in strike resistance, leakage, etc. occur, and there is a possibility that continuous operation will not be possible. In addition, fixing the problem would involve opening the lid of the pressure vessel, which would be a major undertaking. Therefore, there is a need for a method for easily correcting changes in pressure from the outside, such as tightening caused by loosening of screws caused by repeated operation and shutdown, without opening the lid of the pressure vessel.

As shown in Figure #12, the support base 4 of the AK is tightened via the rod 5, the upper part is tightened using the fixing base 6 for fixing the par to the pressure vessel, and the lower part of the fuel cell stack 1 is pushed upwards to remove the fuel. The lower part for tightening the battery stack l is divided into a plate 7.

First, remove the pressure vessel 3, and place the lower clamping plate 7 so that it is in contact with the top of the fixing base 6.For this lower clamping, stack a plurality of fuel cells on the plate 7, and then place the upper clamping plate 7 on top of it. Pass the par, and tighten the fixing base 6 and the rod 5 lightly and evenly. Next, pressure is gradually applied through the pressure fluid supply device 9 until the optimum tightening pressure is reached. This optimum tightening pressure can sometimes be determined by adjusting the internal resistance at both ends of the fuel cell.
