Abstract 1,198,319. Electricity supply plant comprising generator; electrolyser and fuel cell. VARTA A.G. and SIEMENS A.G. 24 Nov., 1967 [25 Nov., 1966], No. 53690/67. Heading H1B. An electricity supply plant comprises a direct current generator, driven, e.g. by a windmill or by water power, a pressure electrolysis battery operated by the generator to produce hydrogen and oxygen, reservoirs connected to receive and store these gases separately, a hydrogen/oxygen fuel cell battery using the same electrolyte as the electrolysis battery and receiving its input gases from the reservoirs, and a pump which circulates the electrolyte between the two batteries when the plant is in operation.
