PURPOSE:To prevent breakage of an electrolyte, anode, and/or cathode consisting of a very thin layer caused by differential pressure, by putting the lower parts of a pair of liquid encapsulating tubes in mutual communication through a communication pipe, and forming a pressure equalizing device. CONSTITUTION:At one of the liquid encapsulating tubes 29 of a pressure equalizing device 32, a pressure chamber 27 is connected with an anode gas exhaust pipe 18, so that the internal pressure of this pressure chamber 27 has becomes equal to the pressure in the exhaust pipe 18, i.e., the internal pressure of an anode gas passage 7. At the other liquid encapsulating tube 30 of the equalizing device 37, another pressure chamber 28 has the same pressure as a cathode gas exhaust pipe 21, i.e., a cathode gas passage 8. As the lower parts of these liquid encapsulating tubes 29, 30 are in communication with each other through a communication pipe 31, liquid can move freely from the tube 29 to the other 30 and vice versa. Accordingly the internal pressure of the anode gas passage 7 in connection with the pressure chamber 27 is kept always equal to the internal pressure of the cathode gas passage 8 in connection with the pressure chamber 28. |
