The aim of the invention is to solve the problem of the humidification of a PEM or an MEA. The invention relates to an electrode plate for a PEM fuel cell, comprising at least one region which is integrated into the same and is used to humidify a reactant flow. The invention also relates to a PEM fuel cell comprising said electrode plate, and to a PEM fuel cell stack containing said PEM fuel cells. The invention further relates to a method for humidifying reactant flows for PEM fuel cells, whereby reactants are humidified in a humidification region after entering the fuel cell and before entering a distribution region. Disclosed is also a method for humidifying a PEM or a PEM fuel cell, and a method for operating PEM fuel cells. The invention especially enables humidification to be carried out in a PEM fuel cell in a simple and effective manner, reducing, for example, volume and weight. |
