Abstract

The invention relates to a fuel cell assembly (4) comprising catalytic electrodes consisting of: (i) a relatively thick layer (8) of porous carbon, said layer being formed by the incorporation of a thermolabile binder which is subsequently decomposed by heating; and (ii) a finely-divided active carbon layer (9) comprising the catalyst. The thick layer (8) ensures that the gases and water formed are well diffused while maintaining a good mechanical strength. The active layer (9) provides a large catalysis surface and a smooth surface that can be used to deposit the ion-conducting membrane (6) under good conditions. Said layers (8, 9) are chemically inert and adhere well to the layers close to the cell.
