[ 22. An anode apparatus for cathodically protecting a metal section in an ionically conductive material, the anode apparatus comprising:
a sacrificial anode of a material which is less noble than the metal section;
an impressed current anode with a DC power supply connected thereto;
the DC power supply is a battery and is included with the sacrificial anode and the impressed current anode comprising common components of a common preassembled unit forming the anode apparatus;
the impressed current anode and the sacrificial anode being electrically separated to prevent electrical communication therebetween;
an electrical connection to the sacrificial anode;
and an electrical connection to the impressed current anode. ]
