Abstract: 1,214,359. Fuel cell gas supply. ALLMANNA SVENSKA ELEKTRISKA A.B. 24 April, 1968 [25 April, 1967], No. 19288/68. Heading H1B. A fuel cell electrode forming at least part of a wall of a gas chamber through which an electrode active gas can pass from an inlet to an outlet is characterized by a porous wall situated across the chamber in the path of the gas, the wall covering no more than 25% of the electrode surface and effecting a gas pressure drop at least equal to half of the total gas pressure drop from inlet to outlet. The wall may be a sheet of fibres or sintered particles, situated midway between the inlet and outlet perpendicular to the direct flow of gas from one to the other. It may be made from a metal or thermoplastic, e.g. P.T.F.E. or poly(ethylene glycol terephthalate). If of metal, it may constitute an electrical connection. A fuel battery may comprise a plurality of such electrodes having a common inlet channel and a common outlet channel. The gas may be oxygen, air, ammonia or a mixture of nitrogen and hydrogen produced by cracking ammonia. In a particular embodiment (Figs. 1-3, not shown) a fuel cell battery comprises a stack of electrodes having circular frames which are thicker than the electrodes themselves so as to space them and provide alternate reactant and electrolyte chambers. The electrodes are of nickel activated with platinum and have a finer pored layer on the electrolyte side. The electrolyte is aq. KOH. The stack is held together by bolts, the joins between the frames being sealed by washers or by sticking them together. Eight bores for the supply and removal of fuel, oxident and electrolyte and for electrical connection pass through peripheral frames, all being open at the same end of the battery, the other end being closed by an end-plate which has no holes in it.

Abstract: IN A FUEL CELL BATTERY WHICH COMPRISES ELECTRODES AND SPACES THEREBETWEEN AND ALSO OUTER SPACES OUTSIDE THE ELECTRODES FOR A COMBUSTIBLE SUBSTANCE OR OXIDANT RESPECTIVELY, THERE ARE TWO CHANNELS, ONE INLET AND ONE OUTLET CHANNEL. AT LEAST THE OUTLET CHANNEL IS ARRANGED AT AN ANGLE TO THE HORIZONTAL PLANE AND WITH ITS UPPERMOST PART CONNECTED TO A DEVICE FOR FEEDING BACK ELECTROLYTE TO THE INLET CHANNEL.

Abstract: 1,200,930. Fuel cells. ALLM€NNA SVENSKA ELEKTRISKA A.B. 18 Dec., 1967 [19 Dec., 1966], No. 57323/67. Heading H1B. A fuel battery has an electrode stack having channels for gaseous fuel, gaseous oxidant and electrolyte formed at least in part by holes in the electrode frames and connecting respectively fuel, oxidant and electrolyte spaces adjacent the electrodes in which there are barrier spaces between frame parts forming the fuel channel and adjacent frame parts forming oxidant spaces and between frame parts forming the oxidant channel and adjacent frame parts forming the fuel spaces, the barrier spaces containing a material which prevents leakage of oxidant and/or fuel into the barrier space or prevents oxidant and fuel which have leaked into the barrier space from reacting, and the barrier spaces being sealed from the respective channels and fuel and oxidant spaces. The material may be water, electrolyte, CO 2 , N 2 or a cured body of epoxy resin; the fluid materials may be passed through the battery to remove gases leaking into the barrier spaces. As shown in Fig. 2, which is a fragmentary cross-section through the fuel channel 13 of an H 2 -O 2 fuel cell, the fuel channel 13 communicates with the fuel spaces 33 adjacent the anodes 26 but is sealed from the electrolyte spaces 35 between the electrodes, and from the barrier spaces 35e which encircle the fuel channel 13, are connected to the electrolyte spaces 35 by the gaps 54 between the thermoplastic resin frames 27, 29 and are filled with electrolyte. Between the oxygen spaces 34, adjacent the cathodes 28, and the fuel channel 13 or the fuel spaces 33 there is thus a space 35e or 35 filled with electrolyte. Welds 50h surround the fuel channel, 51 surround the periphery of the cell and 52g surround the circular apertures 53g in the oxygen frames. The oxygen channel 15 is similarly constructed to be separated from the fuel spaces 33 by electrolyte spaces 35e (Fig. 3, not shown). In another embodiment (Fig. 6, not shown) coolant spaces 57 fed from channel 58 are disposed on either side of the middle pair of cells. In a third embodiment a stack of cells is fed with fuel, oxidant and electrolyte through external, integral conduits in which fuel conduits are isolated from oxidant spaces and vice versa by barrier spaces which are filled with a cured epoxy resin or through which N 2 , CO 2 , H 2 O or other inert fluid is passed.
