A method for producing a porous carbon electrode includes preparing a slurry by mixing a porous, particulate, conductive carbon powder with a solution of a polymer binding agent for the particulate carbon powder in a solvent for the polymer binding agent, forming a precursor electrode by casting the slurry as a layer and subjecting the cast layer to a wet phase inversion to realize porosity in the cast layer, subjecting the thus obtained precursor electrode to a thermal treatment to cause oxidative stabilization, carbonization, dehydrogenation or cyclisation of the polymer binding agent or a combination of two or more of the afore mentioned phenomena by heating the precursor electrode and converting the polymer binding agent into a conductive binding agent binding the particles of the conductive carbon powder together.

Process for producing a porous carbon electrode

A process for producing a gas diffusion electrode comprising the steps of: casting a porous electrically conductive web with a suspension of particles of an electrically conductive material in a solution of a first binder to provide a first layer which is an electrochemically active layer (AL); casting a suspension of particles of a hydrophobic material in a solution of a second binder on said first layer to provide a second layer; and subjecting said first and second layer to phase inversion thereby realizing porosity in both said first layer and said second layer, wherein said subjection of said second layer to phase inversion thereby realizes a water repellent layer; a gas diffusion electrode obtained therewith; the use of a gas diffusion electrode in an membrane electrode assembly; a membrane electrode assembly comprising the gas diffusion electrode; and a method of producing a membrane electrode assembly is realized, said membrane electrode assembly comprising a membrane sandwiched between two electrodes at least one of which is a gas diffusion electrode, wherein said method comprises the step of casting said membrane electrode assembly in a single pass.
