DM15 is a hydrogen fuel-cell power system that converts hydrogen and oxygen into electrical power. Published mass is 8 kg. It supplies an electric propulsion or onboard power installation and requires integration with hydrogen storage and balance-of-plant equipment.
The DM15 is an air-cooled hydrogen fuel-cell power system from Doosan Mobility Innovation, designed as a power pack for unmanned aircraft and other mobile platforms. The module converts hydrogen into electrical energy and delivers it as a regulated DC supply, giving multirotor and VTOL drones a power source with a longer endurance than a battery of equal mass.
The rated output is 1250 W, equal to 1.25 kW of continuous power, at an output voltage of 50 V with a tolerance of plus or minus 2 V, within the 48 to 52 V range. A full DC-DC converter inside the module limits voltage swings caused by changing load. When the load exceeds what the stack can deliver, a regulator board draws on the battery to hold the output steady and protects the aircraft from a high-voltage condition, so the system is intended to run in a hybrid arrangement with a buffer battery on the bus.
Physical figures are given for the complete unit: mass is 8.0 kg including the hydrogen tank, and the dimensions are 275 x 260 x 170 mm (W x L x H). Hydrogen consumption at rated output is 14 NLPM, and the fuel specified is hydrogen of 99.99% purity. The tank is a replaceable item and is not part of the powerpack purchase, so the integrator must plan the tank selection and the filling procedure separately.
Thermal management is by forced air. A 140 mm fan provides cooling, an internal heater supports cold starts, and a control algorithm for low and high temperatures manages fuel supply and cooling together. The module is specified for operation from 0 to 40 °C at 30 to 95% relative humidity, and the same ranges apply to storage. A warranty of 1000 hours or one year applies within the operating temperature and humidity range. Because the cooling is air-based, the installation needs unobstructed intake and exhaust paths for the fan.
Typical applications are VTOL and multirotor drones, robots and motorcycles, with a VTOL drone named by the maker as an example platform. For an integrator, the DM15 fits missions where endurance matters more than peak power, such as inspection, mapping and surveillance, while the battery covers take-off and manoeuvre peaks above the continuous rating.
