    摘要: In a gas fuel cell there are provided bipolar low-pressure electrodes each formed of a flexible graphite foam foil carrying active electrode layers on opposite faces. The gas-side face of each active electrode layer is provided with raised portions which, together with the adjoining foil face, define a channel system forming a closed gas chamber. The raised portions are so arranged that the gas which enters and leaves the gas chamber through an inlet opening and an outlet opening provided in the active electrode layer is substantially evenly distributed over the entire area of the gas-side face of the active electrode layer.
