ELECTROCHEMICAL GENERATOR BUILT AROUND HYDROGEN-OXYGEN (AIR) FUEL CELLS Russian patent published in 2008 - IPC H01M8/04 H01M8/08 

FIELD: electrochemical generators built around alkali electrolyte filled fuel cells and their manufacture.

SUBSTANCE: proposed electrochemical generator built around hydrogen-oxygen (air) fuel cells has fuel cell battery, oxygen and hydrogen (air) supply and blowdown system, and electrolyte circulation circuit; fuel cell battery is assembled of two units, each assembled of set of fuel cell modules of filter-press design with internal hydrogen, oxygen (air) and electrolyte headers. Hydrogen and oxygen (air) circuits of fuel cells are connected within modules in parallel-series manner; hydrogen supply system affording reversible feed has two hydrogen valves of which one valve is connected to one battery unit and other valve, to other battery unit; hydrogen is supplied to bottom hydrogen header in battery units and dispensed within each unit over -shaped circuit.

EFFECT: enhanced operating reliability.
