Abstract

1,114,489. Pumping electrolyte into a fuel cell electrode gas space. SIEMENS-SCHUCKERTWERKE A.G. and VARTA A.G. 19 Dec., 1966 [23 Dec., 1965], No. 56800/66. Heading H1B. Electrolyte is driven into the gas space of a fuel cell gas-diffusion electrode by means of the energy released upon expansion of either (a) the compressed fuel and/or oxidant gas from its storage pressure to a lower pressure not below that of the gas at the electrode inlet, or (b) the exhaust gases leaving the electrode. The expanding gas may drive a piston rigidly connected to another piston which pumps the electrolyte into the gas space of the electrode; preferably the piston is double-acting and is rigidly connected to two electrolyte pump pistons with complementary cycles. Suitable single- and double-acting pumps are described, together with valves for reversing the direction of travel of the double-acting piston and pneumatic, hydraulic or electric switches for operating the valves when the piston is at the extreme positions. In the general system shown in Fig. 1, gas from the tank 1 is led via the reducing valve 3 to the expansion engine/electrolyte pump 7 or to the reducing valve 5 and from these via pipe 9 to the fuel cell battery 10.
