PURPOSE:To make the joint of a composite substrate possible to have constantly high adhesion strength and uniform and low electric resistance even if the size is large, carry out the application process within an extremely short time as a continuous process, and improve the mass production property. CONSTITUTION:In the case that an electrode plate made of a porous carbon material, a separator plate made of a dense carbon material, and side seals are integrally joined into a prescribed cell shape using an adhesive, the adhesive is screen-printed to the parts to be joined through a mesh sheet. The adhesive is preferably a composition containing graphite powders which have different average particle sizes and are kneaded in phenolic resin liquid and having 500-5000 poise viscosity. |
