ELECTROCHEMICAL GENERATOR Russian patent published in 1995 - IPC

FIELD: small-sized transportable electrochemical generators. SUBSTANCE: generator has fuel-cell battery 1, unit 2 for preparing and feeding fuel, heat-insulating case 3, radiation housing 4, profiled screen 5, the first and the second burners 6 and 7, gas conduit 8, unit 9 for igniting gas, accessories and pipe-lines 10, screw insertion 11, through coaxial channel 12. Fuel-cell battery 1 together with unit 2, which is made in form of converter, are disposed inside radiation housing 4. Screen 5, which has to be the bottom of radiation housing, and heater are mounted inside heat-insulating case 3. The heater is made of two burners 6 and 7, which are disposed axially one above the other and directed with their output nozzles opposite. Heat from the burners is accumulated by screen 5 and walls of radiation housing 4. Screen and walls have to be secondary heat supply, which provides uniform high efficient heating of all fuel cells of the battery. In order to provide more uniform heating of fuel cells, heated gases are advanced up by means of gas conduit 8, which is formed by screw insertion, for example, with variable pitch, which gas conduit is installed from outside the radiation housing 4. Anode gas is used as fuel in the second burner, which gas is formed inside the battery. EFFECT: improved efficiency of operation. 5 cl, 1 dwg
