Abstract
A double layered oxygen electrode impregnated with an active catalyst material and method of making. The design of the oxygen electrode promotes oxygen dissociation and absorption within the oxygen electrode. The oxygen electrode has differing layers of hydrophobicity which allow chemical impregnation of the active catalyst material into the oxygen electrode where the active catalyst material is needed most.
