Title: Metal oxygen cell has biporous electrolyte filled diaphragm - and specified capillary pressure ratios in electrodes and diaphragm
Inventor: KLOSS WOLFGANG
IPC: H01M50/489
Filed: 1975-06-13
Abstract: A fuel cell with a negative metal electrode and a positive air (O2) electrode, separated by an electrolyte-soaked porous diaphragm, is so designed that the capillary pressure of the electrolyte in the porous diaphragm is greater than that of it in the porous air electrode and smaller than in the porous metal electrode. The diaphragm communicates with an electrolyte-filled storage system with a smaller capillary pressure of the electrolyte. This absorbs the volumetric changes of the electrolyte during storage and operation. The porous metal electrode remains entirely filled with electrolyte and the contact between air electrode and electrolyte carrier in maintained. Differential concentrations of the electrolyte in the cell are eliminated.

Title: Supervisory circuit for standby battery power supply - monitors battery current as circuit continuity check by use of bipolar relay
Inventor: RABE DIETER
IPC: H02J9/06
Filed: 1975-07-31
Abstract: In a non-break power supply, a battery (11) is employed as a back up source to the main rectifier (2) providing power to the load (3). The presence of a circuit through the battery is continuously monitored by measuring the current in its circuit (1). A shunt (12) provides the input to a bipolar relay (12'). When only minimal current is flowing, that is with the battery charged, the relay drops off. Relay signals go through a time delay (13) to a control element (21) which reduces the main source voltage output slightly, and also to an AND-gate. A drop in voltage causes the battery to provide some of the load current and the relay picks up again, resetting both the controller and AND-gate. The cycle then recommences.
