<P>PROBLEM TO BE SOLVED: To manufacture a multilayer oxygen-consuming cathode having a thin thickness and obtaining required hydrophobicity, so that high impermeability against a liquid and gas through flow can be achieved and electric contact from a gas side is possible. <P>SOLUTION: The multilayer oxygen-consuming electrode has a side facing oxygen-containing gas and a side facing an alkaline electrolyte, and includes: at least one support; and at least two layers containing a catalyst and a hydrophobic substance, wherein a proportion of the catalyst in the outermost layer facing the gas side is lower than that in the outermost layer facing the electrolyte side, and a proportion of the hydrophobic substance does not exceed 8 wt.% based on the total amount of the catalyst and the hydrophobic substance. <P>COPYRIGHT: (C)2012,JPO&INPIT |
