Fuel cell
 

Hi guys, I'm trying to perform a project using PEM Fuel Cells, but I still don't know what approach I can give on this. I need an electrical approach. First I was thinking of using a fuel cell as a DG acting together with a three-phase inverter to provide active power to the grid. Simultaneously, this inverter will act as a APF(active power filter). But my professor said this is too basic, as it is very well known. It is necessary to give a deep electrical theoretical approach.
Any of you have any idea?
