Fuel cell battery
Abstract
Abstract A FUEL CELL BATTERY IS DIVIDED INTO SEVERAL ELECTRICALLY SERIES CONNECTED BLOCKS OF THE FUEL CELLS. THESE BLOCKS AND THE INDIVIDUAL FUEL CELLS WITHIN EACH BLOCK ARE CONNECTED WITH LINES FOR AN ELECTROLYTE-HYDRAZINE FUEL MIXTURE AND THE GASEOUS OXIDATION AGENT WHEREBY DURING THE OPERATION OF THE FUEL BATTERY, THE FUEL CELL ELEMENTS WITHIN EACH BLOCK AND TRAVVERSED IN PARALLEL BY THE GASEOUS OXIDATION AGENT, WHILE THE INDIVIDUAL BLOCKS ARE TRAVERSED IN SERIES. ALL THE FUEL CELLS OF THE FUEL BATTERY ARE PASSED IN PARALLEL BY THE MIXTURE OF ELECTROLYTE-HYDRAZINE. THE NUMBER OF THE FURL CELLS DECREASES PER BLOCK, IN FLOW DIRECTION OF THE GASES OXIDATION AGENT AND THE FLOW RATE OF THE GAS IN THE OXIDATION AENT SUPPLY LINE MAY BE REGULATED BY A VALVE SITUATED AT THE GAS, OUTLET OF THE FUEL CELL BATTERY, SAID VALVE BEING CONTROLLABLE BY ELECTRICAL SIGNALS OBTAINED FROM A VOLTAGE COMPARISON BETWEEN VARIOUS BLOCKS.
