UNMANNED AERIAL VEHICLE WITH FUEL CELL BATTERY COOLING SYSTEM Russian patent published in 2020 - IPC B64C39/02 H01M8/00 

FIELD: aviation.

SUBSTANCE: invention relates to the aviation equipment. Unmanned aerial vehicle with fuel cell battery cooling system including housing (1), fuel cell battery (2) installed inside housing (1), control subsystem connected to air distribution subsystem and thermal sensors (8). Air distribution subsystem comprises air intake openings (6), flow channel (5) formed by inner walls (3) of the housing and outer side walls (4) of fuel elements (2) battery, as well as outlet hole for hot exhaust air emission outside the housing. UAV is equipped with box (10) with air duct (9) installed between battery of fuel elements (2) and outlet hole, so that box walls with air duct divide inner space of housing in area of battery of fuel elements (2) into two adjacent chambers, wherein walls of air duct (9) have holes (13) equipped with bypass valves (14). Thermal sensors (8) are installed at the inlet of air in fuel cells (2) battery.

EFFECT: invention improves design, provides best operation in optimal mode, increases protection against accidents.
