Abstract
In this invention, according to a first embodiment, the collector part of the electrode is formed by a full plate on which are deposited longitudinal strips of polytetrafluorethylene before the depositing of the electrochemically active part. In a second embodiment, the collector part is formed by a grid which is coated, before the depositing of the electrochemically active part, with a zinc oxide paste and polytetrafluorethylene In this way, one or more spaces are provided between the collector part and the electrochemically active part, the result thus being that the gases given off by the reactional process may escape easily by following the space(s), thus avoiding any deformation of the electrode.
