Abstract
A method of manufacturing a cell unit of a fuel cell, including: a) forming an assembly including an electrolyte membrane, an anode catalyst layer coated with a gas diffusion electrode on the side of a surface of the membrane, a cathode catalyst layer coated with a second gas diffusion electrode on the side of the other surface of the membrane, a first reinforcement frame at least partly extending between the membrane and the first electrode, and a second reinforcement frame at least partly extending between the membrane and the second electrode; b) fastening the first and second frames on either side of the membrane; and c) performing a local welding of at least one of the first and second frames to the membrane.
