Abstract: A MAT OF POLYFLUOROCARBON FIBERS HAVING CONTROLLED PORE SIZE AND HYDROPHOBICITY IS IMPREGNATED WITH A CATALYTIC SUBSTANCE TO FORM A LIGHT-WEIGHT CATALYTIC MASS HAVING A LOW, UNIFORM LOADING OF THE CATALYTIC SUBSTANCE. THIS CATALYTIC MASS, PARTICULARLY WHEN COMBINED WITH AN ELECTRICALLY-CONDUCTING ELEMENT, AND/OR A CONTINUOUS HYDROPHOBIC POLYMER MEMBRANES IS SUITABLE FOR USE AS AN ELECTRODE IN AN ELECTROCHEMICAL CELL, E.G. AS A FUEL OR OXIDANT ELECTRODE IN A FUEL CELL OR AS THE CATHODE IN A METAL-AIR BATTERY, WHEREIN IT PROVIDES HIGH CURRENT DENSITIES AT RELATIVELY CONSTANT VOLTAGES OVER A LONG PERIOD OF TIME.
