Gas diffused electrode and manufacture thereof

PURPOSE: To provide the gas diffusion electrode having the excellent gas diffus ing performance to be used for solid polyelectrolyte fuel cell. CONSTITUTION: A sheet-like reaction layer made of hydrophilic carbon black and polytetrafluoroethylene is pressed on a gas diffused layer made of porous carbon base material having water repellency by hot-pressing, or the gas diffused layer is coated with the slurry made of hydrophilic carbon black and polytetrafluoroethylene, and after the carrying, the slurry coated gas diffused layer is dried and burned to obtain a gas diffusion electrode for solid polyelectrolyte fuel cell.
