The invention relates to electrodes and galvanic cells which each have a shaped body which is composed of porous carbon foam and in the pores of which layers of active material and electrolyte, in particular solid-state electrolytes, are formed. The layer comprising electrochemical active material is in this case in electrically conductive contact with the shaped body, and the layer comprising solid-state electrolyte material is in contact with the active material. The electrodes or galvanic cells are particularly suitable for use in electrical energy stores for vehicles, such as in batteriesfor example, for delivering electrical energy to traction motors of motor vehicles with an electric or hybrid drive and are distinguished in that particularly high energy and power densities of corresponding galvanic cells and batteries manufactured therefrom are possible with them. 本发明涉及分别具有由多孔碳泡沫制成的成形体的电极和原电池，在成形体的孔隙中构造有活性材料层和电解质层、尤其是固体电解质层。电化学活性材料层在此与成形体导电接触，并且固体电解质层与活性材料接触。该电极或原电池尤其适合应用于车辆的电能蓄能器、如电池中，以用于为具有电动或混合动力驱动装置
