    Abstract: A cathode for an electrolyser comprises porous conductive material which includes sintered nickel impregnated with, as catalyst, a molbydate of nickel or iron or mixtures thereof. The invention is used for manufacturing hydrogen by electrolysing an aqueous alkaline solution. The cathode may be prepared by impregnating a sintered nickel support with ammonium molybdate solution, then a solution of nickel and/or iron salt (e.g. nitrate), and heating at 450 DEG C in hydrogen.

    Abstract: 1500852 Forced electrolyte flow battery COMPAGNIE GENERALE D'ELECTRICITE SA 13 Jan 1976 [14 Jan 1975] 01228/76 Heading H1B An electrochemical battery comprising elementary cells adapted to be supplied with an electrolyte solution comprising an active material in suspension conveyed by forced flow in said elementary cells, the elementary cells being grouped together into modules, electrically and hydraulically connected together in series within each of the said modules, at least two of the modules being substantially identical and arranged in a stack one above the other and electrically interconnected in parallel, the battery being arranged so that the solution enters the upper module 1a, Fig. 2, at the input of its upper elementary cell, flows through the upper module and into the input of the upper elementary cell of the lower module 1b, Fig. 2, of the stack and flows from the lower module through the output of its lower elementary cell. The constituent elementary cells may comprise a negative collector grid a, Fig. 1, a porous separator b, a porous active catalytic layer c, a positive collector grid d coated with a waterrepellant layer e and the electrolyte may comprise Zn suspended in KOH. Pumps 10 and 12 or 22, Fig. 2, may be used to circulate the electrolyte and various configurations utilizing a plurality of modules, electrolyte reservoir tubes, pumps, electrical and hydraulic connections are described and shown in Figs. 3, 4, 5 and 6.
