1,144,322. Fuel cells. ELECTRIC STORAGE BATTERY CO. 22 March, 1966 [22 March. 1965], No. 12534/66. Heading H1B. In a fuel cell the electrodes are arranged in the upper part of a reservoir of electrolyte containing or in a space communicating therewith and not below the level thereof and the fuel reacts to form a product which further reacts with electrolyte to form a product which is denser than the electrolyte; the downward diffusion of the denser reaction product under gravity serves to displace electrolyte rich in fuel upwards towards the electrolyte. As shown in Fig. 1, the fuel cell 11 has a navigation light 10 mounted thereon and powered thereby via a converter. The reservoir 13 contains a fuel (methanol) dissolved in a KOH solution and in its upper part the fuel cell comprising hollow nickel/silver cathodes and silver/palladium sheet anodes separated by polythene netting. CO 2 produced by oxidation of the methanol reacts with KOH to form K 2 C0 3 which gravitates to the bottom of the reservoir displacing fuel rich electrolyte to the top. External carbonation of the electrolyte is prevented by a layer of mineral oil 23. Control 18 periodically vents the cathodes through vent 22. |
