Abstract
1318974 Fuel cell elements SIEMENS AG 17 July 1970 [26 July 1969] 34911/70 Heading H1B A component for building up fuel cell batteries comprises a pack of flat elements which are in sequence: an electrically conductive, liquid-impermeable separating sheet 30, a spacer 32, an electrode 34, and a liquid-permeable diaphragm 36, whose edge is secured to the separating sheet, the elements being sealed into an electrically insulating frame 37, which contains at least one enclosed channel 38, through which electrolyte can flow. The embodiment shown in Fig. 2a also comprises a second electrode 33 and a spacer 40 to provide an electrolyte space. The separating sheet may be of nickel, the spacers of metallic gauze, the liquidpermeable diaphragm of asbestos paper, the frame of epoxy-resin and the channels closed with metal or plastics foil 39. In a second embodiment-Fig. 1a-the fuel, e.g. hydrazine, is supplied in the electrolyte, e.g. KOH, and so several of the components can be omitted. In this embodiment, the electrodes may be of Raney silver and Raney nickel.
