There is a class of galvanic cells in which the negative elementis protected from polarization by means of metallic oxides. Ofthese the best known is the Leclanche cell (Fig. 364). In this cellthe carbon plate C is contained in a porous cup P, and packedround with fragments of gas-retort coke and manganese manganese compound has a strong aflBnity for the hydrogen
