THIN CARBON-CLOTH-BASED ELECTROCATALYTIC GAS DIFFUSION ELECTRODES, PROCESSES, AND ELECTROCHEMICAL CELLS COMPRISING THE SAME

摘要

Thin gas diffusion electrodes comprising an open pore carbon cloth substrate [1] provided with a uniform mixture of catalytic carbon particles and preferably Teflon particles [2, 3] adhered within the cloth pores and to the yarns of the cloth; processes for making and using the same; and assemblies comprising said electrodes and closely spaced preferably noble metal current collecting contacts [4] for use in electrochemical cells operating at high current densities.
