1. A galvanic cell for treating an aqueous composition, the galvanic cell comprising:
a planar anode comprising Al;
a first and second cathode having the anode therebetween, the first and second cathode having a different composition than the anode and comprising Cu, wherein the first and second cathode comprises a porous cathode material, wherein the galvanic cell is free of an external electrical potential applied across the anode and first cathode and across the anode and the second cathode;
an electrically insulating connector that physically connects the anode, the first cathode, and the second cathode and maintains a gap between the anode and the first cathode and between the anode and the second cathode, wherein the anode, the first cathode, and the second cathode are free of direct contact with one another; and
an electrically conductive connector that electrically connects the first and second cathode to one another.
