Abstract
An improved porous electrode for use in electrochemical cells, particularly for use in fuel cells. The electrode is of the kind comprising a porous layer containing carbon and a non-polar resin such as polytetrafluoroethylene, and an electrically conducting screen acting as a collector. To prevent early collector deterioration the collector material is covered with an electrically conductive protective layer, which consists either of an electrically conductive resin or of a non-conductive resin in which conductive particles, such as graphite particles, have been incorporated.
