υ′に泡性能の低下や爆発の危険性があった。With this method, each manifold can be attached to the frame (2 bars 3) around the entire circumference with screws, so the sealing performance between the two is clearly the same as above, but each reaction gas manifold + 4J (5
The frame (3) to be installed on the floor has intermediate partitions (3 to 34K has a tightening force of 2711
Rather, the sword flies in the direction of floating above the stack surface as shown by the arrow in figure M8. As a result, the intermediate partition pressure was insufficient, resulting in a decrease in sealing performance and cross-reaction of both reaction gases, resulting in a decrease in foaming performance and the risk of explosion.
