ABSTRACT:
A fuel cell battery of the filter press-type which uses a liquid electrolyte and at least one gaseous reactant, with the individual fuel cells which make up the battery having gas and electrolyte chambers separated from each other by asbestos diaphragms with the asbestos diaphragms having electrolyte-impermeable, gas-tight outer zones of increased thickness which are pressed together or against separator sheets and contain supply ducts formed therein, in which the width of the outer zone of increased thickness on the electrolyte side is made smaller than the width of the same part on the gas side and where the means such as a support frame or electrode causing separation in the electrolyte chamber are sized to extend beyond the inner edge of the outer zone on the gas side.
