Claim Text:
1. A method of manufacturing a gaseous diffusion electrode, comprising the steps of: a) providing a stack successively comprising a gas diffusion layer, a catalytic layer, and an electrolyte diffusion layer; b) forming a first layer of thermoplastic polymer material on the gas diffusion layer and a second layer of thermoplastic polymer material on the electrolyte diffusion layer, the first and second layers of thermoplastic polymer material each having a shape of a frame of the associated diffusion layer; c) folding the stack to arrange a first portion and a second portion of the gas diffusion layer in front of each other; d) folding the stack to arrange a first portion and a second portion of the electrolyte diffusion layer in front of each other; and e) bonding the first and second portions of the gas diffusion layer by means of the thermoplastic polymer material of the first layer, f) bonding the first and second portions of the electrolyte diffusion layer by means of the thermoplastic polymer material of the second layer.
