A membrane electrode assembly (MEA) for a fuel cell and an electrolyzer is provided. The MEA includes a first electrode layer, a second electrode layer disposed opposite the first electrode layer, a polymer electrolyte membrane extending between the first ...

The method involves assembling a proton-exchange membrane with a gas diffusion layer (104), and securing a surface of the gas diffusion layer with a surface of the proton-exchange membrane. Anodic electro catalytic ink is deposited (106) on another surface...

A membrane-electrode assembly for use in a reversible fuel cell comprises an ion conductive membrane having first and second surface; a first electrocatalyst layer in contact with the first surface of the membrane said first electrocatalyst layer comprisin...

An ion-exchange membrane may be continuously coated by depositing a catalyst composition on a release surface, drying the catalyst at an elevated temperature and then transferring the dried catalyst layer onto an ion-exchange membrane by applying pressure ...

The membrane electrode assembly 1 has an anode 10, a cathode 20, and an electrolyte membrane 30 disposed between the anode and cathode; the anode and cathode are gas diffusion electrodes; the electrolyte membrane contains a solid electrolyte in which a plu...

The invention relates to a method for producing an electrode-membrane-electrode assembly on a cylindrical substrate (1), characterized in that the electrode-membrane-electrode assembly is produced by successive deposition of an electrode layer (2,3), a mem...

In a process to make a membrane- electrode unit, separate first and second gas distributor layers incorporate hydrophobic carbon- based substrates. The substrates have selected inks containing a catalyst, dissolved ionomer and solvent. The first gas distri...
