The flight range of multi-copter drones is limited due to their relatively short battery life. Hydrogen fuel cell drones feature an extended flight time can change this equation.
For aviation, fuel cells must be light and maintain stable high power during flight. Hydrogen fuel cells have high energy density, which can significantly increase the operating time and distance of urban air mobility (UAM), an ecosystem involving flying passenger vehicles in urban areas.
The South Korean Institute of Energy Technology Evaluation and Planning has selected Hanwha Aerospace to lead a national task – the development of a fuel cell system for urban air mobility – in a four-year project that would cost some 21 billion won ($17 million), according to ajudaily.com.
The company will establish a consortium with domestic companies and research institutes in order to secure core technologies by improving performance and reducing system weight by 2025.
