Drones Design

a very difficult problem since the canister that holds hydrogen needs a thick wall and is very heavy !!

there are literally thousands in the open market that are sized to the motor electrical parameters. figure out your aeronautical requirements, then motors, then props, then batteries, and finally power to weight ratio. the 'art' is finding the perfect (subjective) balance based upon what is important to you or your project. - - no two projects are the same !!

I have concept of how to generate electricity using the hydrogen as a fuel. but is bigger size and not developed till date just a concept. working or not depending upon research.

Eh, the composite ones aren't crazy.

uh, Yes they are ! Look again !! They lightest and smallest one here is 26 Kg = 58 lbs

Now design me a drone that doesn't look like some single engine airplane !

How big is your Hydrogen drone going to be and how much weight can it lift, since the canister to hold hydrogen is heavy and the combustion chamber to burn hydrogen is heavy too.

Hydrogen may be good for ground based vehicles, but not for small drones. So unless you want to design a hydrogen airplane; not happening !

Airplane - yes ; Small drone - no.

我公司设计了四轴固定翼无人机并已成功测试，搭载2KW烟囱，使用9升气瓶，烟囱和气瓶总重量约7KG。现在的问题是如何设计出更适合携带气瓶和烟囱的机架设计

so with your 9KW engine and 9 liter of hydrogen how far do you expect to go ?

also the 7 Kg of TOTAL weight seems amazingly good.

provide the link to your company website so i can see it for myself.

我公司（江苏燃料电池氢能科技有限公司）是一家成立于2020年的氢能公司，主要是一家开发氢燃料电池电堆的公司。无人机是我们公司的一个项目，关于9升气瓶和2KW堆栈的无人机，到目前为止我们只测试了它的续航能力，还没有测试它全功率能飞多远

它可以飞行近2.5小时

Congratulations,for new creation Well i have different design and concept of to produce electricity from hydrogen gase.
