Abstract
The invention relates to a process for the production of a layer of an electrode for a cell, particularly for a fuel cell, starting from an electrically conductive fine-grained powder and a powdery binder, according to which the powder and the binder are mixed in dry condition and the mixture is rolled to form a layer, characterized in that the dry mixture is subjected to an agglomeration step, the agglomerates obtained are broken and pressed together to form a whole and the pressed whole is rolled, in various steps, to form a layer. The process also relates to the production of an electrode containing such a layer.
