Electrode signs in a fuel cell

Hello!

I was confused by the electrode signs in an alkaline hydrogen fuel cell. I know that in a galvanic cell the cathode is positive, but in an electrolytic cell, it's negative.

Isn't a fuel cell a galvanic one? Why is the cathode negative? And how do the electrons move after the redox processes?

Thanks a lot,
