A gas generating galvanic cell for the transport of fluid media is composed of an anode, a cathode and a housing containing an aqueous electrolyte. By closing an outer circuit, a current is made to flow within the cell, generating an amount of gas proportional to the current flow. A cell is used that in its initial state contains a) only a substance capable of being electrochemically oxidised, a hydrogen generating electrode and aqueous electrolytes or b) only a substance capable of being electrochemically reduced, an oxygen generating electrode and an aqueous electrolyte. When subjected to a current flow applied from the outside, the cell generates hydrogen or oxygen that are formed in the pores of a gas diffusing electrode and escape through the pores of a hydrophobic diffusing membrane, the electrolyte being held inside the cell container by the high capillary depression of this membrane.
