1,066,465. Fuel cells; primary cells. MONSANTO CO. Oct. 22, 1963 [Oct. 22, 1962]. No. 41596/63. Heading H1B. The separator (10, 11) of a fuel cell is moved continuously past electrodes 12, 13 fuel and anolyte being applied at 14 and oxidant and catholyte at 15. The tapes can be wound on a spindle 18 by clockwork. In many modifications the separator may be a single tape and may carry any or all of the components of the cell, having the stationary part merely to function as carrier collectors. Thus, fuel and oxidant may be supplied in liquid form by running the tapes through baths before they meet the current collectors, or by including encapsulated liquids in the tape. Gases may be pressed in a plastics foam applied to the tape (e.g. fluorine gas) and solid fuel and oxidant can be coated on the tape. A dissolving electrode (e.g. Mg,. Zn, Al) may be used on the tape to give a primary cell couple. The tape may be endless and cut to feed fuel &c. to the reactive sites and the current collectors (or electrodes) may be in the form of rollers or endless bands thus facilitating depolarization by a continual change of surface. Many fuels or anodic materials are disclosed, including urea, guanidine and glucose and many solid and liquid oxidants, including organic oxidants such as meta-dinitrobenzene. A copper, copper oxide couple can be used as oxidant and in this case an endless copper band forms the electrode and is re-oxidized by the atmosphere. The separator may be of ionexchange resin. |
