Abstract: A connecting device for a fuel cell including a cell carrier strip wound into a spiral, the device includes a tube provided with an electrically conductive outer surface and an axial electric connection terminal, as well as with a connection terminal for a first gas and radial ports for the passage of the first gas. The tube forms a channel for the distribution of the first gas between the connection terminal for the first gas and the radial ports. In addition, the device includes an electrically insulating sleeve for receiving the tube, the sleeve being provided with an open longitudinal window opposite the ports on one side of the sleeve.
