A galvanic cell or battery is powered by a centrally disposed anode and an outwardly, edgewise-spaced and disposed group of outwardly disposed cathodes of dissimilar electrolytically reactive metal, and has lever-operated lifting means or spring means for automatically adjusting the relation between the cathodes and the anode as the anode is destructively worn away during power generating utilization of the battery. The adjusting means is adapted to exert lateral, radial or axial pressure on the group of cathodes to urge them against insulating means which defines a desired operative spacing between the anode and the group of cathodes. Wire screen material is folded or wound about and is secured on a centrally positioned metal backing member to provide cathode elements.
