A porous electrode for an electric cell, said electrode including a support layer and an active or catalytic layer, the thickness of the electrode (1a, 1b, 1c, 1d) lying between about 50 and 600 microns and preferably between 100 and 250 microns, the active or catalytic layer (2) and the support layer (3) each including 60 to 99% by weight of a hydrophobic polymer or binder and 40 to 1% by weight of a carbon-based divided conductive compound the two layers being, in the aggregate, hydrophobic and intimately joined, current being drawn off at points or lines which are spaced apart by a distance of about one millimeter from one another by an electronically conductive collector (4) in contact at the points or lines with the support layer (3). |
