Abstract

1,216,290. Fuel cells. SIEMENS A.G. 21 Feb., 1968 [23 Feb., 1967], No. 33233/70. Divided out of 1,215,630. Heading H1B. A method of operating a fuel cell with a porous, gas-diffusion electrode and a liquid electrolyte comprises temporarily establishing communication between the electrolyte and a gas at a higher pressure than that of the electrolyte when it is not in communication with the gas, at a location remote from the electrode so raising the hydrostatic pressure of the electrolyte and flushing the pores of the electrode therewith. Preferably the gas is the reaction gas and the communication of the gas with the electrolyte is controlled by an electromagnetic valve which is automatically operated when the electrode potential falls to a preselected value.
