The invention relates to a method for manufacturing a portable electronic-chip-comprising object including a body and a metal-air battery that is integrated into the body, the battery comprising an electrolyte layer and a protective air-porous membrane covering the electrolyte. The method includes a step of forming at least one air-supply duct extending from the protective membrane to an air source. An air-porous material is contained in the duct and completely blocks the duct at least in one place on its course. The invention also relates to the object corresponding to this method.

A printed fuel cell having integrated gas channels, and having an anode layer, where a first gas diffusion electrode layer is periodically fixed to the anode layer, wherein the periodically fixed first gas diffusion electrode layer defines hydrogen flow field channels. A first catalyst material is coated or infused to the first gas diffusion electrode layer. An electrolyte membrane covers portions of the anode layer and first gas diffusion electrode layer with the first catalyst material. A second catalyst material is coated or infused to the electrolyte membrane. A second gas diffusion electrode layer is in operative association with the electrolyte membrane and second catalyst material, on a surface of the electrolyte membrane different from a surface of the electrolyte membrane which is in contact with the first gas diffusion electrode layer, and a perforated cathode is in contact with the second gas diffusion electrode layer.
