1338131 Fuel cell batteries SOC GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES (ALSTHOM) 19 April 1971 [2 March 1970] 22890/71 Heading H1B In a fuel cell battery of the type comprising components such as electrodes and separators stacked in a repeating sequence between end plates, opposing peripheral sides of each component have apertures such that when stacked, channels are formed, only some of which communicate with the cell interior and each end plate has within the thickness thereof chambers connecting the communicating passages with passages that do not communicate. The communicating passages are arranged to supply the electrodes with electrolyte having dissolved or emulsified therein the appropriate reagent. The non-communicating passages provide a return path so that both inlet and outlet of a particular reagent may be located on the same side of the cell by making connections to the non-communicating passages and the chambers of the end plate. The connection to a chamber is preferably nearer to the associated non- communicating passage than the communicating passage. The end plates may be made by "lost wax" casting about fusible or soluble cores using hot or cold resins reinforced by metal plates. Alternatively the plates may be assembled from separately tooled parts. |
