Gas diffusion electrode comprises a gas diffusion layer and a catalyst layer a porous electrolyte and microporous catalyst-electrolyte aggregate

摘要

Gas diffusion electrode comprises a catalyst layer and a gas diffusion layer. The catalyst layer contains a porous electrolyte A having pores joined three dimensionally to each other, and a microporous catalyst-electrolyte aggregate containing a catalyst and an electrolyte B. An independent claim is also included for a process for the production of a gas diffusion electrode comprising arranging a microporous catalyst-electrolyte aggregate containing a catalyst and an electrolyte B in the pores of a porous electrolyte A.
