1,111,589. Fuel cells. COMPAGNIE GENERALE D'ELECTRICITE. 1 Dec., 1965 [2 Dec., 1964], No. 51071/65. Heading H1B. A fuel cell whose electrolyte concentration increases on operation has its electrolyte compartmont connected to the electrolyte compartment of a fuel cell whose electrolyte concentration decreases on operation, the electrolytes being the same, so that when the cells operate jointly any tendencies for a decrease in concentration in one cell is compensated by electrolyte from the other cell. In one embodiment a diluent is supplied to the cell whose electrolyte becomes more concentrated on operation and an electrolyte exhaust is provided for the other cell. In another arrangement the electrolyte flows in a closed circuit from one cell to the other and back again. Cells whose concentration decreases on operation comprise: aluminium-alkali hydroxide, e.g. potassium or sodium hydroxide, -oxygen; zinc-hydroxideoxygen; borohydride-hydroxide-oxygen; hydrogen-hydroxide-oxygen ; hydrazine-hydroxide-oxygen and hydrocarbon-hydroxide-oxygen. Cells whose concentration increases comprise sodium-hydroxide-oxygen cells. In a further modification two fuels are supplied to a single fuel cell, one of the fuels tending to increase the electrolyte concentration and the other tending to decrease electrolyte concentration. |
