PURPOSE:To miniaturize the equipment and to eliminate the need for an electrolytic cell clamping pressure fixing device by arranging a multiple electrolytic cell and a plate heat exchanger on the same plane in a water electrolytic device, clamping and integrating the cell and the heat exchanger with a common bolt. CONSTITUTION:A heat exchanger 12, a gaseous oxygen cooler 13 and a gaseous hydrogen cooler 14 on the opposite side are put side by side on one side of a multiple electrolytic cell 11 provided with a high molecular electrolyte membrane, clamped by plural through bolts and integrated as a composite 10. A DC voltage is impressed between the anode and cathode of the cell 11 from a DC power source 40 to electrolyze the water in the cell 11 into oxygen and hydrogen. The oxygen generated on the anode and the unreacted water are separated by a separator 30 into oxygen and water, and the high-temp. oxygen is supplied to the cooler 13, cooled by water and discharged outside the system through a valve 70. The hydrogen generated on the cathode and the entrained water are cooled with the cooler 14, and the hydrogen is discharged outside the system through a valve 80. The cell 11, the exchanger 12, the gaseous oxygen cooler and the gaseous hydrogen cooler 14 are clamped together by the common bolt at a specified pressure in this way, and consequently the whole device is miniaturized. |
