1,196,926. Fuel batteries. GAZ DE FRANCE. 29 Sept., 1967 [3 Oct., 1966], No. 44577/67. Heading H1B. In a battery of fuel cells each cell is a flat disc (1) comprising a porous matrix containing fuseable electrolyte (4) and separating a porous anode (5) and cathode (6) and is held by its edge(s) in a hole in a plate (3) having a thickness equal to that of the disc, each plate retaining several discs. In examples matrix (4) is of MgO or LiAlO 2 , the electrolyte is an eutectic mixture of Na 2 CO 3 and Li 2 CO 3 , the anode is sintered nickel and the cathode sintered silver or a sintered mixture of silver and copper oxide. The plate (3) may be made from a refractory material or made from metal, e.g. stainless steel and coated with refractory material, e.g. zirconia, except at the edges (7). All the cells in each plate may be joined in parallel by conductive films (9) and (10) of nickel and silver respectively and these coatings joined by wires (29) and (30) to connector bars (31) (32). The plates are stacked to form a battery, each pair being separated by a frame 11 of steel or ceramic material providing a reactant reservoir between the plates. Fuel and oxidant reservoirs alternate up the stack of plates. Borings in the frames and plates provide bolt holes (22, 23) for assembly of the battery and conduits for the supply and removal of fuel and oxidant (14, 15, 24, 25). Each conduit communicates with appropriate reservoirs by slits (18, 20) in the frames (11). The plates of the battery may be joined in any desired arrangement. For example in an 8 plate battery 4 paralleljoined pairs of plates may be joined in series, 2 parallel-joined quartets of plates may be joined in series or all 8 plates may be joined in parallel. The illustrated embodiment may be modified by making the discs, plates and frames triangular, square or hexagonal. The battery may operate at 500-900‹ C. |
