PURPOSE:To prevent leakage of gas certainly by placing heat resistant/ electrolyte resistant mixed/kneaded substance and fluororesin tape provided with a holed portion is sealing materials between an electrode end having ribs and a gas separating board. CONSTITUTION:Mixed/kneaded substance 5 formed by mixing together and kneading 30-60wt.% of heat resistant/electrolyte resistant scaly graphite powder, and 70-40wt.% of fluorine oil, and porous fluororesin tape 6b provided with a holed portion 7 are placed as sealing materials between the end of an electrode 2 having ribs and fluororesin film 4 bonded thereto and a gas separating board 3. Accordingly, the end of each electrode 2 having ribs and fluororesin film 4 bonded thereto and a gas separating board 3 adjacent thereto can be enhanced in their resiliency and adhesiveness, so that any gas leakage from gaps between these components can be prevented certainly. |
