Intelligent Energy has developed hydrogen powered drone using two hydrogen fuel cells. Inventors say solves two of the biggest problems associated with drones: flight time and re-fuelling. The global commercial drone market is expected to sky-rocket in the coming years, reaching close to 5 billion euros by 2020 but it’s being held back by the short range and long re-charging times of conventional batteries. With fuel cell technology the flight times significantly increase, up to between an hour and two hours and no need to recharge the battery, all you need to do is change the fuel source and that takes around a minute. Intelligent Energy says it hopes to have its fuel cells on commercial drones within the next year. The company is also working with a smartphone manufacturer to create a phone that lasts up to a week on hydrogen fuel cells.
