Abstract

864,457. Electrolysers; fuel cells. E.R.A. PATENTS Ltd. Sept. 19, 1957 [Aug. 23, 1956], No. 25802/56. Classes 41 and 53. An electrolyser for water, which can be operated in reverse as a gas battery or fuel cell has porous nickel electrodes in which the pores in the faces in contact with the electrolyte are smaller than the pores on the opposite faces so that the generated gases force the electrolyte out of the pores but are prevented from bubbling into the electrolyte. The electrode at which oxygen is evolved is provided with a porous non-conducting coating on the face in contact with the electrolyte whereby the oxygen is prevented from being liberated directly into the electrolyte. The apparatus shown is similar to that described in Specification 864,456 and comprises a stack of bipolar electrodes 1, each of which consists of a central nickel plate having a recess on each side containing porous nickel which is spaced a short distance from the plate. The spaces between the electrodes are filled with a solution of potassium hydroxide. The outer faces of the oxygen electrodes are coated with porous non-conducting green nickel oxide, or magnesium oxide, and the inner faces are prevented from corrosion by a layer of black nickel oxide containing lithium, as described in Specification 864,456. Current is supplied to the electrodes 1 and hydrogen and oxygen are evolved from the rear faces of the nickel fillings and are led away through passages 51, 52. Specifications 667,298 and 725,661 also are referred to.
