The methods of this project consist in the construction and programming of the UAV. Fort this research project The implementation of a Hydrogen fuel cell in the electric system of an UAV, is a procedure that consist in the design,creation and operation of a Blimp. For the design of the blimp we took the project Silent_runner that consist in the construction of a racing blimp. The Silent_runner is a UAV and being this project sourceful for us in terms of the viability of the creation of an UAV blimp we variate the design to be able to fit to our own concerns like the implementation of the Hydrogen fuel cell system to it.
Construction: Hull
Airships have, other than planes or helicopter, about the same weight as the surrounding air. This is achieved by the use of a lifting gas like helium or hydrogen inside a large envelope. The principle of being “lighter than air” opens up several advantages, but on the other side has some drawbacks. Airships use very low energy, as they don´t need to waste power for floating. On the other hand, airships are, due to their large size and low density, sensitive to wind. In the past and nowadays, endless efforts were put into the design of efficient airships. The results of these efforts are collected in the simple and straight forward design of our blimp, featuring easy assembly and standard components.

Electronics
The Electronic System Controller (ESC) runs out of 10 Amperage, controlling the motors rpm and voltage that pass through them. Motors and ESC are connected by three wires. The circuit board used for the operation of the UAV is an Arduino UNO (figure 1). This will control and regulate the …(list all systems). The 6.4 GHz receiver will be connected to the Arduino board and will regulate the output and input of current passing through the circuit. Soldering is also needed to prepare the Arduino and to fit all the cables to the correct length. All solder joints would be isolated to avoid any short circuit between them.
Balance
The airship´s balance is an important part, and before flight, the ship should be balanced to a perfect horizontal level. This allows a straightforward flight. For a good balance the parts of the airship must, regarding to their weight, be placed in a way the weight is spread over the whole ship with the center of gravity below the center of buoyancy.
Code
For processing control inputs and output to engines and control surfaces, an Arduino is implemented. This microcontroller is programmed with a specific code that translates the inputs by formulas to the desired outputs. Code development is done in the Arduino environment. The code consists of very basic parts, which are essential to control the ship, but can be expanded easily
