1. A method of preparing an electrocatalytic gas diffusion electrode with an open pore carbon cloth, comprising the steps of depositing a first uniform mixture of noble-metal-catalyzed carbon and a hydrophobic binder on one side of said cloth and adhering said first mixture within the cloth pores and to the yarns of the cloth to a depth less than the thickness of the cloth, and similarly depositing a second uniform mixture of non-catalytic carbon and a hydrophobic binder to the remaining open pore portion on the other side of said cloth and adhering said second mixture within the cloth pores and to the yarns of the cloth to a depth less than the thickness of the cloth.
