FUEL CELL POWER PACK FOR MULTICOPTER
First Claim
1. A fuel cell power pack used as a power source in a multicopter having a plurality of arms and rotating blades symmetric about an aircraft body in a horizontal direction, the fuel cell comprising:
- a fuel tank mounted on the aircraft body to store hydrogen fuel of a gaseous or liquid state;
a battery mounted on the aircraft body together with the fuel tank to store electrical energy generated as the hydrogen fuel reacts with air and supply the electrical energy to a driving motor which drives the rotating blade; and
a fuel cell stack for producing the electrical energy by reacting the hydrogen fuel supplied from the fuel tank with oxygen in air flowing in from outside and supplying the produced electrical energy to the battery,wherein the fuel cell stack is mounted on an arm within an area affected by a thrust of the rotating blade.

Abstract
A fuel cell power pack used as a power source in a multicopter includes a fuel tank and a fuel cell stack for producing electrical energy using hydrogen supplied from the fuel tank and supplying the electrical energy to a battery, and since the fuel cell stack is disposed at a certain point of an arm extended from the aircraft body in the radius direction (a point affected by a descending air current generated by each rotating blade), the electrical energy can be produced using the descending air current generated by the rotating blade without configuring a separate blowing apparatus.
