Hydrogen Fuel Cell Aircraft Model

[Olga Currás Vallejos]

Hello! 

I am trying to model a hybrid battery - hydrogen fuel cell aircraft. I have seen that there are some already implemented features, but they are very incomplete and outdated.

I wanted to ask if someone knows if there are any new updates regarding the battery and fuel cell models, or any person that has more knowledge in this area that could help me.

Thanks in advance!
