994,083. Fuel cells. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. Nov. 17, 1961 [Nov. 24, 1960], No. 41309/61. Heading H1B. A fuel cell wherein a combustible substance is combined with oxygen in the presence of at least one catalyst is characterized in that hydrazine is included in its electrolyte as a combustible substance. The electrolyte may comprise an aqueous solution of potassium hydroxide, preferably 40% concentration, and 1 to 5%, preferably 2%, of hydrazine. The anode may comprise 80% of finely ground active carbon, 19À5% of silver oxide catalyst and 0À5% of platinum black catalyst, the whole being agglomerated by compression and sintering. The cathode may comprise 48% "Raney" nickel, catalyst (" Raney is a Registered Trade Mark), 48% of nickel in the state of a fine powder conductor and 4% of palladium sponge catalyst, the whole being agglomerated by compression and sintering. Electrodes so constituted act as catalysts and permit combustion of hydrazine at temperatures from 0‹ C. to the boiling-point of the electrolyte, the preferred range being 15-100‹ C. In Fig. 1, the cathode 1 and anode 4 are in the form of circular discs enclosed in a gas-tight insulating casing 7. A perforated silver plate 5 is attached to the anode and is connected to a lead 6. Electrolyte is passed through the space between the two electrodes, and air or oxygen is supplied through tube 11 to the anode, which is sufficiently porous to allow the gas to pass through it to the electrolyte. |
